​@@ianmangham4570 unfortunately Shimano doesn't pay much attention to square taper anymore, up until not long ago they used their special sealed cartridge bottom bracket design, like the BB-UN26 on the video. Bearing wise, they were more like the traditional cups & axle design, except integrated in a sealed cartridge. Nowadays they've moved away from this great design, and if you look at their current offerings such as BB-UN101 or UN300, it's just two cartridge bearings and a tube, like any other bottom bracket cartridge out there. In fact the bearings shimano uses appear to be much narrower than what other brands use, can't imagine that can be good with the forces they have to withstand.

I know the most outdated component on my bike is ME! I also know, in the beginning, some Freewheels could be completely dis-assembled with a couple of cog wrenches. You could actually select the number of teeth you wanted on each cog (sprocket) of the set of five. I believe the most outdated set of cogs on bicycles is a 10,12, 15, 18, 21, or 24 speed cluster that ends with a 14 tooth High Gear Cog or Sprocket. Cycling is based on the old Weight to Power ratio. The lighter the better! 11, 12, or 13 tooth cogs are lighter in weight than 14 or 15 tooth cogs. If the size and weight can be reduced at the rear wheel it can also be reduced at the Chain Ring. Better ground clearance would be a big advantage for off-road cycles (BMX and Mountain Bikes). One thing BMX did for Cycling is to bring longer crank arms into the picture. 180 cm crank arms instead of 160, 165, or 170s. That, of course, puts more stress on the bottom bracket. That stress is concentrated right where the aluminum crank arms meet the square tapered steel shaft. Most of the bearings used in sealed bottom brackets are off the shelf items from electric motor industrial applications. They do have an angular contact specification and a much better riveted ball retainer built right into them. They are made to run at revolutions no man will ever achieve at the cranks (1700 RPM or better). The same rules apply to the bearings used in sealed bearing hubs for bicycles. In the early days of BMX SR made a tubular one piece chrome-molly crank. Hollow from pedal threads to pedal threads. It was made for the American Bottom Bracket. I had a Schwinn Continental with an SR Tubular installed. It made it a little lighter. I rode it in the 85 Lake Hefner Streak. That was the indestructible crank. I had a Bike with a Shimano 8-Spline BB shaft. Stripped in no time! No Thanks! Hollow BB shafts are available for square tapered types. I think it's funny that for the first 15 years of Mountain Bike production there was not a Kevlar belted tire, in sight, anywhere. There were Kevlar belted IRCs for Road Bikes and Touring models the whole 15 years and still today! You have no ride without Kevlar! 72 in June!

You can remove the individual sprockets from a freewheel. If you did not notice the smallest sprocket is what holding the others in place. If you unscrew it then you can remove any sprocket and replace it if you find one.

I agree. That said, the freewheels and square taper cranks on my old bikes still work well and are easy to maintain. The cartridge bearing system on my newer Cannondale bike works well, but I need to buy expensive tools to maintain it, and the removal / install process is more complicated.

None of the reasons mentioned for Cassette vs. Freewheel are remotely sensible. The primary reason for a cassette is it allows the bearings in the rear hub to be roughly equally spaced, reducing hub wear and torsional load.

But it's out of date so their is not a lot of options . You can not get single gears . But at 8 bucks for a whole set . Not a big deal . It's also not hard to take off if you use the "chain whip" tool .. if I where bored and wanted to spend money I might change the newer freehub . Cause there is more gearing options .

Exactly! All my bikes have square tapered bottom bracket. One touring bike I have had since 1985 still has the original BB with separate bearings, cups and spindle. It's very tough if you maintain it once every few years. I don't race so the stiffness or a few grams of weight mean nothing to me. The newer inventions came and went quickly. The Octalink BB was called revolutionary, then was obsolete in about 5 years.

You didn't mention the biggest disadvantage with freewheel. The hub axle is unsupported within the freewheel which results in broken axles and bent quick release

There's a reason some things are still around. It's because they were well designed to begin with. It's all well and good to go down the path of having the latest and greatest but for those of us who enjoy lugged frames and the classic (ever-serviceable) tech and who like to remember where things came from, the older stuff will still have appeal to riders and collectors alike. My daily rider is a 1985 Fuji Professional with a Suntour Superbe Pro groupset (friction shifting) and my newer ride is a Scott CR1 SL with SRAM Red 11. From a performance standpoint the Scott certainly leaves nothing to be desired and it's what I use for my long distance and high elevation gain rides but there's an undeniable silkiness with which the Fuji goes about its business, not to mention the more forgiving nature of its lugged steel frame, that makes it just so much fun to ride. I also don't feel weird about locking it up when I'm running errands. It also helps that it was the exact model I wanted when I was a kid but could never dream of affording. Surely, technological progress is important and will continue to make our lives "easier" but I'm one of those people that likes to look forward while also looking back, not forgetting where we came from and not losing my connection to the old ways.

I totally disagree with square tapered bottom bracket. For racing - sure, the 2-piece cranksets lower weight and A BIT better stiffness (not a huge difference actually!) will benefit. But for touring and commuting, where longevity is the thing, the square tapered bottom bracket beats the shit out of external bearings in 2-piece cranksets. Especially while frequently used in bad weather conditions. My personal experience on my touring bike - after riding down 3 sets of bearings for 2 piece cranksets, each one lasting approximately 1500km i sold the crankset and switched to square tapered one. After 8000km it's still in pristine condition. You did not mention the crappiest relic that is still commonly used in some tourers and commuters, especially dutch bikes - the threaded headset!

That said, extreme Touring requires a rider to be able to fix things on the road, where ever and whenever in order to survive the trip. This means, unlike road cycling where you come home every trip, touring exists in a world of pragmatic ludditism, in that it's not so much the risk of failure, because after 1000 miles in a few weeks a failure becomes inevitable, but the risk of your broken bike being unfixable. It is likely that when things go wrong, it'll be far from a minor city and farther still from an LBS which has the newest parts in stock. Which means that while a 2 piece crank might be superior technologically in every way; that fact is little comfort if those parts fail (for whatever reason), you can't fix them, and then you're stuck walking 200 miles in the middle of sister-fuck nowhere. At least thanks to square taper's extreme cheap ubiquity and age you can sleep easy knowing that almost any town with even a cheap Kmart bicycle shaped object will probably have the parts and the tools to fix a broken square crankset and BB. Failing that the tools used to service square tapers can be easily approximated and parts could be kludged together in a friendly machine shop or tractor supply, hell it beats walking.

Are you sure that you can find an external BB wrench deep within pennsyltucky, the South American jungles, the desert, or central Africa? And forget about adjustments, how certain are you that you can find the newest replacement parts within the distant forgotten regions of the world? Bikes are everywhere, but external BB are not, because they aren't cheap. QED, square BB have THREE advantages, they're cheap, they're easy to source because they're everywhere, and, in a pinch, they don't require special tools.

BBs are not hard wearing at all- not if you are riding outdoors. even in perfect weather, your bb will get contaminated and you will have to repack, but before you do your bearings will get pitted. 17 years is not proof you speak with any authority- in 17 years you should have have plenty of learning experience gained from necessary work on your own bike, including mistakes, but you speak as though everything was perfect from day one as proof your square BB is better. Square BBs have been snapped clean in final sprints. Everyone not living in florida or saskatchewan who rode "back then" will remember the large chainring rubbing on a good climb if you forgot or failed to downshift in time. Or a bit of play caused by loosening of the cups, breaking-down/wash out of grease, or perhaps an italian thread, binding caused by over-tightening etc. But nope, you dont.

If it ain't broken, don't fix it. My 2 cent.

I like the part about spreading the bearings out. This is another reason why freewheels are not good. They force the axle bearings inward on drive side, which leads to a lot more broken axles. With bearings closer in, they give the axle a longer lever arm. This produces a larger moment about drive side bearings than would occur with most cassette hubs of the 10mm axle type.

There's no maintenance issues with a freewheel as you simply replace it when it wears out. Also it means you have a simpler hub which is a good thing. The main downside of a freewheel hub is weakness. The design was pre mountain bike and the exposed axel will break easily on rough terrain. The way to remove it easily is by placing the remover tool in a vice/vise and turning the wheel.

I have broken rear axles in road bikes. So freewheel type hub is a slightly less durable design for axles.

Just bought a yukon fat tire Ebike it has Free wheel how would i change to the good caset ?

My first long distance tour was on a hollowtech 2. It was also my last. In 2010 I ate through two hollowtech BBs. I had had the frame faced and the BBs were installed in different countries/workshops. When touring I often carry quite a bit of weight (including my guitar) as well as putting out quite some power. The bike often gets very wet (Norway was pretty wet in the summer of 2010. I've since gone back to square taper. The weight with decent components is pretty comparable but I do notice some flex when pushing a lot of watts. That said I've never had a un55 fail on me and have a square taper that has done at least 40 000km.

You missed the main advantage of the cassette which is that it allows us to put the bearings of the cassette out near the hub axle-nuts or QR nuts, so the axle is supported at the ends and is under much less stress and breaks/bends far less often. That's essential for 135mm MTB hubs and good for 130mm hubs. When were multi-cog freewheels invented? Maybe 1930's? 1940's?

I just got rid of my Octalink BB and cranks just this past weekend and replaced with the Deore. The Octalink shells needed a impact gun to remove

I've been using my GXP bottom bracket for the last 6 years and I only regreased it once and it is still in perfect condition and no lateral play.

If your square taper cranks are moving around, it's because someone tried to install them by just tightening the nuts/bolts on the arms. A square taper joint MUST be hammered on, and no I don't mean taking a claw hammer and beating your arms to a pulp. A deadblow hammer with repeated blow/tighten, blow/tighten, will set the wedge in the taper without damaging anything in the BB.

My bike cost 600 AUD, it has a cassette not a free hub and a sealed bottom bracket with tapered roller bearings but has a tapered square crank spindle. Is it worth upgrading my commuter bike with a two piece crank and bracket?

Question. My bike has a square tapered bottom bracket. Is it possible to install the newer system on it? Like, is it compatible or are the measurements different?

Octalink vs square taper- stiffer, but smaller bearings wear out quicker. That said, I use an old Deore octalink on my single speed mountain bike because for high- torque low rpm as you said the hollowtech 2 pich bolt system couldn't handle the lateral forces and the LH crank would invariably fail. SRAM GXP doesn't have this problem however and I generally use this on my road bikes. External bearings wear out quicker than internal ones due to road/ off-road grit exposure. I don't really notice much flex on the inexpensive but decent Sugino 110BCD square taper crank on one of my road bikes. Cartridge bearings- tough enough, never noticed an issue with lateral loads in wheels, but this could contribute to rapid wear in cranks. Cheap and easy to set up. Freewheels- biggest issue is that the rear wheel isn't supported at either end, stressing the axle. They are however MUCH cheaper than cassettes and freehubs. Never had an issue with removal and I'm a strong 90KG who rides quite aggressively- you just need a long lever.

Bottom brackets have become a serious pain in the last few years. And failure can lead to an unusable frame. The external bearings are lighter and stiffer in all applications. 45 years of wrenching has shown me that most riders do not maintain their bikes to the level they should. I would much rather deal with the old adjustable cone and bearings than the BS and problems I have found with the newer pressed bearings and the carnage that some people impose on their bikes. Square taper is fine in many stetting's, like road, city and touring were forces are linier and steady. But, they are not as stiff where serious torque application is necessary. And, if you fail to keep specified torque on the left bolt there is a risk of the arm getting wallowed out. If that happens it's toast. If BB threads become rusted, corroded or packed with grit, especially around beaches and coastal areas, they are a bear to remove or impossible. A hundred times I've found them cross threaded. With press fit I have seen damage to the frame from badly installed or removed bearings.

Hi Torchedini, you're probably right in some countries, but a 7sp cassette is hard to find nowadays. I've had Shimano freehubs fail and had to replace them along with the cassette, which is quite expensive, but never (as far as I recall) had a freewheel fail, they'll wear out before then and are quite cheap. Biggest problem is the lack of support for the axle at the right-hand end with a screw-on hub, I have seen plenty of solid axles bend with a heavy rider and have broken a couple of QR axles myself, back in the day. Freehubs are better in every way bar price IMHO.

@yonseimatt

Bryan, agreed. I've lost a few decent cromoly frames to seized in bottom brackets. Most folks don't maintain their bikes anywhere near as well as they should.

these things come down to cost. Square taper cranks are cheap... hollowtech, GXP cost more The biggest problem with the freewheel btw is bearing positioning along your rear axle. I have snapped 3 rear axles (QR) the last year due to the drive side bearings being so central to the hub. Also I use square taper, octalink and hollow tech II bottom brackets on my fleet (depending which bike). Nothing wrong with any of these systems but they all do something different. My favourite for ease and longevity is the hollowtech II which is on both my hardtail and full sus MTB. Square taper would literally fall apart if i tried using it for riding trails. I ride road every day on the square taper, doing about 1500-2000 miles a year in all weathers and I'm sorry, but I can't believe anyone who says they've been riding the same square taper BB almost 10 years without the bearings giving up on them. Mine go about every 6-12m. The only way they are lasting nearly a decade, is if you barely ride.

Hi, small question, My casette has a slight "rotational" play on the freehub. Is that normal? Or is no play allowed? The bike is 5 years old Greetings Serdar

Square tapered bottom brackets are great as long as you make sure that the bolts holding your cranks on them are kept tight.As any movement would warp the soft alloy of your cranks,rendering them useless.Ideally you should use thread lock on the bolts. But grease the pin to stop creaking sounds. I used them for years with very few problems. They are also more durable in my experience than the splined or octolink ones. One problem I did find with the square ones,was that they could end up welding themselves to the crank,if not serviced pretty regularly. I certainly don't think they should be made obsolete. I remember the old serviceable cotter-less bottom brackets well also,as long as you installed them properly they were great,and with good regular servicing they lasted years,they also had the square taper.

Misses the point about durability and cost.

I like both options for different reasons. i love my classic bicycles with cup and cone, however, the cartridge bearings are super easy to quickly service. i did notice that both of my experiences with cartridge came not adequately greased from the bicycle shop / factory. i had to service them very soon after purchased, but since have been great. i do like the simplicity of the press fit cranks, but have had little problems with my classic square taper too. also, i suspect the old stuff will outlast everything as i have seen in the comments too. in the end, i like having the options for different purposes. more importantly, bicycles are awesome. :)

The biggest problem with the is the bearing placement on the axel. Because the drive side bearing is about an inch further inboard than the bearing in the freehub heavy vertical forces like those in routine mountain bike use causes the axel to bend. Then that happens it puts causes contact, friction and wear in the bearings. As well as increasing the already bad wobble of the sprockets and chain line. It leads to eventual failure of the freewheel. The HG system that has become the basic standard was designed specifically to address this problem for mountain bikes and has been carried over to basically all bike disciplines.

John here from the Philippines. We still have unsealed Bottom Bracket. It is the kind where you change the 2 bearings and add grease every 3 months. Bearings are like $0.30 a piece. We also use unsealed bearings for our axles, we open it up once in 2 months to add grease and change the bearing if busted. We also have bikes the still use the quill stem. The freewheel is great! It sometimes last the same lifespan as the frame, rust and wear and tear-wise with our imperfect roads. A lot of use still have sections of commute where the concrete is 50 years old hence bumpy or gravel and mud, e.g. the rice and sugarcane plantations. Here our BMX, MTB's and road bikes we use for commuting, average 5 kilometers one way or more. We can only swallow at most $2 of maintenance per week. Our daily minimum wage is about $8. A brand new Chinese- made mountain bike is $190. We are happy enough to buy Japanese surplus commuter bikes and maybe mountain bikes, the few that they are at $230. The cheapest of the local used BMX bike here could be both for $30 but that amount is like food for a family of 3 in 1 week. We survive on $2 interior and $6 tires which last us a year. It might be outdated where you are but we might be forced to walk the distance without them.

Iv had a campag chorus square taper bottom bracket in my bike for 20 years and done thousands of miles on it. Its still runs slick and as good as the day it was fitted.

How much money does Shimano give you for this? Or are you just hoping for free stuff?

Not every bike is for racing. When they start making components for the largest segment of bicycle production (under $300), only then will you start seeing the "outdated" stuff going away. The stuff just isn't cheap enough to set the bar for the lowest common denominator.

To be fair he's not really talking about commuter bikes and touring. I do hate freewheels though.

I have two square taper BB bikes, one octalink, one Hollowtech and a BB30 cartridge bike. The square tapers are fine, a little heavy. The octalink is an obvious improvement at the crank/axle interface. The Hollowtech is perfect. The BB30 constantly creaks and cracks.

Good Clip. I noticed a big improvement going to HollowTech II Cranks. And am a big fan of Compact 50-34 Teeth for the older riders. With Ultegra 32-11 11speed cassette for steep hill climbs. Thanks.

Free wheels are replaceable without scrapping the wheel

+Chris Witek: same bike, I assume? More expensive frames are also usually much stiffer. My external cup BB in my steel track frame is much less stiff than the octalink in my an aluminium racing frame. And, the only modern carbon frame, I've tried felt no more stiff than the (almost 20-years old, back then pro-level) aluminium frame (and, that is why I still drive with it).

I have about 8000 miles on a sealed bearing square/tapered bottom bracket. Works great, no movement of the crank arms, and I carry said tool with me. Then again I am a trained bicycle mechanic. The more complicated you make a bike, the more its apt to break down when you need it.. I have rebuilt wheels, bottom brackets and headsets using "Loose" round ball bearings. I've never seen a Angular ball bearing in my life. My Cousin used to work for a Japanese company that makes sealed/Cartridge bearings. I will soon replace the front wheel of my recumbent bike, with a wheel using sealed bearings. Sir, you really need to rethink this video. Talk to a Bicycle mechanic, show him this video and see what they think. Last thing, the spindle on a square/taper bottom bracket is made of Chrome Moly Steel, the crank arms are made of aluminum, and its the square holes in the crank arms that round out, unless you keep them tight.

Man i have been searching on youtube for like 24hr watch time, but ur video was finaly the one which told what are benefits of different types of BB n why one is better than the other. i was in dire need to know why should, n to what type of BB should i Upgrade to. THANX A LOT!

i would go with the up grade on my bike with a complete set brakes included. love this alot, good information for me and the problems i have had in front and rear.

I have a two piece crank that uses the octalink connection on one side, the only special tool I seem to need is a really big crank Allen key, it works well because you can get the tension up on the crank shaft much easier.

About bearings: you just don't think for yourself! For the bottom bracket: even with a load slightly out of alignment, the balls are still resting on the races and not touching the space between the two rings. Changing to angular contact would require tightening from the sides, which would cause more friction and a loss of efficiency. Angular contact are useful in the headset, where you have forces coming from two directions: vertical from bumps, and horizontal simply because the head tube is at a 73° angle which pulls the steerer forward at the bottom and pushes it back on the top end.

If you turn off the volume on this video and simply watch, it looks like a 1970s/1980s "Fingerbobs" episode #beingold

I prefer cup and cone bearings. I put custom cup and cone bearings on my midschool Haro Mirra BMX, and it felt a lot better than the typical BB bearings

fantastic video! I would just mention another of the main disadvantages of the freewheel: the bearings are less wide in distance -->less torsional stability of the wheel

When you "upgrade" these parts and they feel stiffer, smoother, more efficient it's just your subconscious tricking you so you don't feel bad about spunking your hard earned on something you already had!

Not sure about everything you said, but it's normal I guess.... I think cassette and derailleurs and chains are obsolete. Make a gearbox already!

IMHO square taper will NEVER BE OUTDATED! Why? Because for one they are stronger than any other type of crankset I've ever used - and I beat the crap out of my bikes, having been a messenger. Plus most square taper cranksets use SEALED BOTTOM BRACKETS where your supposed 2 piece (really a 3 piece as you have to include the bottom bracket along with the two other pieces) use an external bottom bracket which is NOT SEALED, therefore letting things like water and dirt get inside, making the life of the BB less than that of a sealed one. (currently on year #9 with the same exact square tapered crankset and bb and it still works the same as the day I bought it.) So no, I don't think square taper is outdated. Sorry.

I like square taper, but not sealed cartridge square taper. I find the seals more than adequate on the modern external threaded cups, and I love the easy maintenance of old cup-and-cone systems, but I can't stand the disposable cartridges - they're heavy, expensive and unreliable, and you can't fix them when they start to wear. I have two shimano 105 chainsets - a 1056 with cartridge BB, and a 5800 with ultegra external bb. I love the look of the old one, but it is noticeably less stiff, and though it is extremely light without a bb, the weight of the cartridge is significant.

The biggest difference between Square-tapered bearings and Hollowtech is. Lifetime of square-tapered is around 15-20 years and Hollowtech some 3-5 years.

I have heard so much nonsense in this video. Square tapered bottom brackets are strong and stiff. There heavy, but use larger ball bearings thus more durable. If you get chainrub on your front mech i think your frame is flexing. Maybe a stiffer frame or just use proper gearing? Most of the Olympic Track cyclists use Square tapered bottom brackets, and those guy's can push big gears. Don't believe everything the manufacturers tell you. They once said that bb30 was the best option for bracket mounting. But after a decade i know my next bike will have BSA threading for my MTB and Road bike.

From personal experience, I can make my chainrings flex if I really push in the hardest gear on a 52 front, 11 rear setup. Even with a brand new BB there is enough flex to make the chain rub the front mec. I can't make this happen with a hollowtech crankset/BB. It is stiffer for sure.

I had an old Swiss made cup and cone square taper set up once and so long as it got serviced properly worked faultlessly. Not got the bike anymore so it's gone now but since then I've had real trouble finding another bottom bracket system as good. The new systems you showed us in your video look nice and they obviously have their advantages but if I could just get my hands on a good quality vintage type again I'll be happy.

He missed the primary weakness I see in bikes with freewheels vs freehub hubs. My customers regularly break the axle on the 7 speed freewheel bikes. This is due to the placement of the bearing on the drive side. The freewheel bike has that right side bearing located closer to the center of the bike than the freehub bikes. This is where the axle breaks. The freehub style hubs have the bearings located more outboard on the drive side. The other things noted are somewhat true, but there are a lot a caveats that go with that statement that I will not enter on a forum like this.

You should never hit a fixed axle you will shorten the life of the bearings, put some heavy grease on the axles before assembly to allow the arms to settle correctly, i have never had a loose crank arm.

Yeah, the old freewheel is getting old hat now along with cup n cone bottom brackets but everything here is all still totally usable on our good old everyday rides as long as you look after them and keep up with maintainance! Essentially not everyone is bothered about saving a few ounces/grammes unless they're serious racers when weight limits come into play.

I'm on the original Shimano square taper on my MTB after 17 years; no extra flex apparent from the frame itself, and the bearings spin smoother than any external cup system I've yet found. Heavier, but the flex issues are grossly exaggerated except for pro peloton sprinters. The inherent alignment of the left and right bearings allows tighter tolerances, seals, and minimal play versus external cups that inevitably are out of plane, get water and grit nearly as fast as the original open cups before the sealed canister became the norm. External cups allowed large tubular spindles for weight and stiffness, but at a high cost of reliability and well, cost. Ironically now that bottom bracket openings are large enough, Shimano and others may revert to a single sealed unit which would press or thread into one side and contain both bearing sets, coming full circle and providing the proper alignment the bottom bracket part of the frames themselves have failed to provide.

There has never been a freewheel made in which it's impossible to swap out any of the original sprockets. Do some homework. Thumbs down, no subscribing.

I've put a BMX-style bottom bracket and crank on my 26" dirt jumper. It's basically a mix of that octalink system and the non-drive side clamp of that crank set u showed. The teeth on the axle are much longer and taller tho, and it's a CroMo axle so I'm sure it's gonna last longer than I live. And the bearings in the BB cups are accessible from the outside so they should be very easy to replace. I'd prefer that same crank system on my other bike which has an octalink BB and crank set and a 1x9 shifting group on it but I'd need a 32T chain ring in the front to be able to reach proper speeds and I'm not sure 32T chain rings exist for the BMX-style cranks.

The only issue with square taper axles is that getting the right axle length for new cranks was sometimes difficult, but that was due to lack of specific information because they date from before you could look it up on the internet. Even if you have to test fit one and swap it out you still spend less time overall because the bearings don't shit themselves in less than a year.

The lighter weight of Hollowtech compared to squared tapered is the biggest lie ever! Separate the Spindle from the crankarm and put it together with the bearings on a scale. My square tapered "Tune" bottom bracket weighs about 180 gram. Now you!

I am surprised that you didn't attack solid wheel hub axles as being outdated. Personally, I swap out QD hollow axles for solid ones which you can still buy new. QDs are fine for racing, but if you are going to lock up your bike to a sidewalk rack, or tow a trailer, solid is the way to go. I just carry a 14-15mm wrench which also fits pedals and crank bolts. Consider this a pre-emptive strike for keeping those 'outdated' solid axles that also resist bending and breaking. I am also a big fan of 5-speed freewheels, cup and cones, square taper, quill stems, etc. Call me a retro-grouch.

not sure about the square taper ... think about the ROI .... mine is fine after 8 years .... im looking to up grade my crankset as the chainrings are slowly wearing out .. square taper with replaceable rings is the way forward for me

You are forgetting the last piece on the most modern systems: - Cassette: the freewheel needs to be somewhere, if it's not in the cassette it is mounted directly to the wheel. - Cranks: the bottom bracket is still there, now it is mounted on the frame directly and the bearings are easier to replace. - Bearings: bearings are sealed, meaning you can't add grease to the inside of the bearing without disassembling a dust cover, the reason grease grease is applied to the bearings is to act as a seal for water and dust which could find it's way inside the bearing and wearing out faster. About the forces you mentioned, I have my question mark there, before I should do some math and see how much are the actual forces compared to a high speed machine...

Good video! BMX cranks have had hollow chromoly and titanium cranks for years. Other companies like Bullseye, Hutch, Redline and Profile have had their 2 piece axle/crank combo as well.For over 30 years. With 48 spline axles and larger bearings. Profile has a line that fits into euro bottom bracket with outboard (larger) bearings housing (ceramic bearings sold aftermarket). The setup with hollow chromoly cranks, Titanium gun drilled hollow axle, and ceramic bearings. Is lighter than Shimanos standard crank setup and 5X times stiffer and 2.5X stronger. So yes, It was outdated over 30 years ago but the J.I.S. axle is still a classic for some applications. The other hollow axle stuff Shimano inadvertently copied over the years..., skip it and go for the real Profile stuff... you wont regret it! Great video to discuss bike tech!

Nothing wrong with the square taper design . Simple. effective. I bet the square taper is stiffer than the hollow one.

I switched to Chris king headset on my trek 6300, Chris king bsa BB 30 will be installed too, with Race Face turbine cranks. I can't use the cheap outdated stuff because I destroy them by riding them, I'm about 75 kg with all gear on.

Square taper is good when not over tightened. When I switched to 105 Octalink crank from 600 square taper crank It definitely felt stiffer but that could the crank. I think maintenance is easier with the newer cranks. You can mushroom square taper cranks if you don't use torque wrench.

1:41 this video is starting to remind me of my Doctors appointment.

I believe, that motorcycles usually have cartridge bearings for their hubs.. Don't know if they are radial or something else though.

Cartridge/cup cone - less mainintence and more durable, slightly more friction than high end cup cone but whatever. Depends what you are after, my vote is cartridge all the way since I need less things to think about. Cassette>freewheel cassette - this one is eaey Hollowtech cranks - not so fast, yes it has the performance and lightweight but bearings are extremly sensitive to water and some ht2 systems on mtbs are prone to loosing the tightness of non drive side crank. Generally not as durable as newer type octalink (DH bikes almost never use ht2 cranks). Depends on the user....

I disagree with the square tapper bottom bracket being 'out dated'. My touring bike has this with (over three tours now) completed done 94,000 km without a problem (using two Shimano bottom brackets). If I was racing / gram-pinching then yes a lighter method would prove beneficial, it's all a matter of application.
