Sir, I have vintage folding bike, I would like to replace to cup type BB with a sealed one, found out the bike's bottom bracket shell is 73mm, in our country the available in the market is 68mm(there's also 80mm). I have a sealed BB 68mmx115mm, obviously it's undersized. What if I get 68mm x 127.5mm and put some spacers?

@@haldyordan2316 Um... if your shell is 73mm, or 5mm wider, adding spacers is the opposite of what you want to do. And spacers have nothing to do with spindle length. Spindle length adjusts how for the cranks stick out. You need to look a the specs of the cranks for what spindle length to use. Different cranks require different spindle lengths. www.sheldonbrown.com/cribsheet-bottombrackets.html

I just found out that 73mm bottom bracket shell, the inner treads a bit larger, so cups from the 68mm a bit loose, my idea buying a longer spindle set a lost cause 😅

@RJTheBikeGuy

@@haldyordan2316 The spindle length comes from the crankset specs. The other measurement, (68/73) comes from the bottom bracket shell width. So if your frame shell is 73mm, you need a 73mm BB.

Although worth investing in a BB Cup tool. The Adjustable Crescent Wrench... Rounding nuts since 1905. Hateful implement.

Great video. One tip for anybody still learning: whenever you have the bottom bracket out of a bike, before you clean out the bb shell, that's the perfect time to pull the seatpost and clean out any rust, corrosion, or gunk in the seat tube and hit it with some Boeshield. Then you can just clean up everything down below before reassembling. Thanks for the great content, RJ!

These are the best bike videos, with outstanding close-up camera work, and thorough commentary. For people like me who often learn the hard way: be sure to screw the crank remover tool all the way in to the crank, as far as it will go, before tightening down the plunger part--this to avoid ruining the soft aluminum threads in the crank arm. Also, I was at first unable to slide the sealed bearing assembly all the way through the bottom bracket on my older Nishiki mountain bike, because it ran into a screw protruding through the bottom of the bottom bracket, a screw that attaches a plastic cable guide under the bottom bracket. I had to Dremel down the screw to accommodate the sleeve containing the sealed bearing assembly.

Top tip when mounting a BB; screw in the non drive side a lil first, that way its supported on that side preventing the driveside from cross threading! Is usefull with slightly worn off threads on old frames!

Your videos are indispensable for fledgling bike mechanics like myself. Thank you so much for all that you do.

I want to make a confession. I use your videos as white noise while i work because i find your voice very calming if that makes sense at all. Of course i do pick up some bike maintenance tips along the way. :)

I find my voice annoying. LOL!

I have been watching a bunch of your how to fix bike vids lately, just got back into cycling after a thirty plus year hiatus. I picked up a couple old Treks, an 800 mountain track, and a 730 road bike. I am working my way through them and riding them and thanks to you I will be able to get all the wearable parts back to pristine working order for short money once I Aquire a few more tools. I can't thank you enough for all the good work you have put into these excellent how to vids. The savings in labor will cover the cost of my tools, and I can have the satisfaction of doing my own work.

*Some missed parts.. red reflector. No kick leg, the one in picture I got it separately. **Latest.Bike** Was easy to assembly. Instructions are clear. Very good idea to take it to a bike shop for tune up. If you have tools, knowledge and time easy to make it ready for a ride.*

Following a series of seven botched jobs across three new bikes from a bike shop, I decided to do my own work. Among the first things I did was to replace the cup and cone BB with a sealed bearing BB. Fortunately I'm mechanically savvy so the job went perfectly after watching such a video. I buy tools as I see a need for them and have built up a collection. I love working on bikes and it's great to have help from the videos.

RJ, thank you so much for this video. It was perfect for what I needed to repair a vintage to a sealed BB cartridge. Despite the terminology differences, you work in metric and show critical tips about clockwise and anti-clockwise, what to measure for the size of the replacement etc., that I just could not find on other "so called" tutorials. You have made me look like an expert to my kids. That was even better than fixing the bicycle :-) You will be my first channel to check for any future repairs that I am not familiar with.

Cool!

this is the only part of the bike i was afraid to work on. now i feel i am ready to install a new bottom bracket. clear and simple explanation as always, thanks Bike Guy!

I used to love working on bikes, I miss it! spent 5 years working in a shop making no money but I would say that life was simple and I enjoyed it :)

I was so confused about the size of bottom bracket I would need and I always took my bikes in the past to my local bike shop. The bike shop is closed now and I don't know how to message for a new one but now I know. Thank you so much, you are awesome. I know it is a square taper and I know everything else, I just didn't know what to measure and I was confused about the new bottom bracket sizes.

I just found how to size the length of the shaft or spindle of my bicycle. I always find your video so clear and easy to understand. Thank You, RJ the Bike Guy.

Your videos give me the confidence to do my own repairs and upgrades on my ‘79 Nishiki road bike - I’ve changed all my cables and put on new bar tape so far… next up is bottom bracket and crankset. Thank you!

RJ, Thanks for all the "how to" videos concerning bicycle maintenance, in my opinion you are the best on youtube! Thank you very much! Rick

His videos are an excellent template for presenting instructional videos. I've seen far too many videos on KZread where the presenters waffle about everything under the sun and forget the actual purpose of the video. RJ's videos have taught me loads about bike maintenance and saved me quite a lot of money as well.

I replaced the old-style bearing races with a sealed cartridge on my 30-year old bike. This video was very informative and helpful. Thanks!

Thanks for this great video. I'm building from the frame up for the first time, very helpful.

Once again, you and your videos come to the rescue of this fledgling bike mechanic! Thanks so much!!

I dont know much about bikes and going through ur helpful videos makes me confident in repairing my bike ... thanx ..

Definitely a good tutorial on how to switch a spindle to a bottom bracket! Tks a lot!

When I see your videos, I wonder how other tutorial videos manage to do it so badly, great video :)

Super efficient teacher. Excellent editing and great video. Not a second wasted. Fabulous. Thanks.

Thank you for the information! Just what I've been looking for.

I like your video man! You are smart, and all were explained perfect! You did this video two year ago, but it still helpful. Thank you!

I can’t stress how important it is not to cross thread . I learnt the hard way thankfully my patient bike shop got it sorted. Thanks for your videos. I’ve just finished restoring my 25 year old mountain bike. With your help.

Your detail is paramount to successful bicycle repairs. Not all work comes easy, but once learned it becomes more timely & easier.

Shimano UN55...the best BB. You can feel the stiffness under your feet. And last years, if install correctly. Great video RJ.

Fantastic! Thank you for this video. This was very, very helpful.

Excellent information! I couldn't shift the RHS retainer so I used an electric heat gun to warm it up and it came loose easily without the need of a hammer.

Excellent instructional vid. Very informative. Thanks.

Good demonstration and answered some questions I had about which measurements to take.

thx for the informative video. i have a '99 Stumpjumper FSR XC that had a tiny bit of crank/bb play last time out. had an ill fitting wheelset i was trying at the time which could have contributed. these old suspension bikes with the bushings/bearings are not maintenance free but other than cleaning chain/cassette, i have not had to remove cranks yet. but this vid can be my tutor when the time comes. meanwhile, on my commuter and fitness bikes, just 3 and 6 years old, i routinely remove and clean/regrease cranks and bb at minimum annually. my NOS 2010/'14 Trek has needed 3 chains, 3 cassettes and 3 gear cables. Incessant dropped chain under hard pedaling forced swapping the 3x10 for a 2x (without changing the shifters). And headsets on both the 21st century bikes needed bearings & regreasing. even the fat bike i built last winter snapped the plastic FD tab during cable install. but this 18 year old Stumpy shifts like new, and needed nothing but a cable and chain lube. still running the original cassette/chain. when the bb or crank finally do fail, i will upgrade as you have here, to a Hollotech or Race Face Turbine. thx again for inspiring confidence.

Very nicely done. You make it look so easy. Thanks.

Thank you so much for this. I haven't been able to find anywhere how to take a vintage bottom bracket out (didn't realize they don't use the same tool to remove)

Hey RJ thanks for all the nice videos. Learned a lot from it!

Nice job. Sealed cartridge is better today. I never knew this possible.

Thank you RJ. Your videos have helped me immensely. Much appreciated..

I don't mind the "go-aheads" because the video content is great. But now that I'm here..."go-ahead" is used when something you're about to say is obvious, like a surgeon telling his assistant, "go ahead and stitch him up," after an operation. When you're watching a video for something you don't know how to do, go-ahead is not really appropriate. Another pet peeve of mine out there is "actually", ha ha. RJ, thanks for taking the time to share your knowledge with everyone, I don't mind.

Very good. Now I know exactly what I need to order and do. Thanks 😊 .

OUTSTANDING!

Thanks for your video. I'm ready to open for the commute bike shop. But just experienced mountain bike. Good video.

Nicely and cleanly explained. you are amazing

I only use Shimano UN55 cause they are the bomb! You can feel the difference when you pedal than say a stock SR Suntour Crank that it used on most mid price bikes. Thanks for the video, you always make informative videos.

Clockwise, flipping BRILLIANT, THE WORDS I HAVE SAID TODAY!

useful tip! thank you.

Again, impressive.

Very interesting video!!!

Make sure to check for a washer behind each crank center bolt before attempting to use the puller! They must be removed or the puller will not work, and the crank arm threads and tool threads can be damaged. Also, there’s a chance the bike has an Italian threaded bottom bracket. If this is the case, the drive side bottom bracket shell won’t be reverse threaded. Knowing this is important to avoid frustration/damage by trying to remove it as a left hand threaded shell. Also, it will help to ensure buying the correct bottom bracket.

This certainly was helpful for upgrading the bottom bracket on my Mongoose Ledge 3.1. Seems like no matter how much I adjusted the bottom bracket with the old caged bearings, the slop would eventually return. So my chain ring had a wobble to it. Definitely feels better than it was brand new. It even shifts better. The chainring is slightly closer to the frame now, so the chain no longer rubs with the front derailleur in top gear.

@BrownJello

3 жыл бұрын

That rub can sometimes be adjusted / some shifters have a "trim" to move the derailleur slightly one way or the other; similarly some systems are not supposed to run certain gear combos (a 2x8 system running 1-8 will rub with the chain running so cockeyed). [General info for all] Looks like your situation is a bonus perc

@kcg795

Since then, I swapped the rear wheel that used a 7 speed freewheel to a wheel that now has an 8 speed cassette. Had to upgrade the rear derailleur and shifter in the process. I mainly did this upgrade so I can have hydraulic disc brakes in the rear. Now when my front derailleur is on the small ring, the chain won't start rubbing until I get to about 3rd or 4th on the rear derailleur. Once I'm on the 2nd chain ring, it's nice and quiet. It shifts insanely smooth now. Oh, and the sealed bottom bracket is holding up quite nicely.

Thank you! You saved me some money. I almost bought a 35mm bb and a special crank set because I thought the measurement was about the height of the bracket.

Thanks a ton here, great video. I didn't have that special spanner to remove the lock ring on the adjustable cup so I cut small 10mmx10mmx250mm red oak sticks as sacrificial blow to knock that ring loose after soaking in pb blaster over-night (didn't "bugger" up the chrome plated lock ring notches that way). So I'm rebuilding my brother-in-laws mid-80's chromoly Montagna Tange Sakae SR group oval-tech 26" MTN bike so it's certainly not the one-offs like Italian or French. My spindle is NOT symmetrical. On the drive side there's about 3 more mm from the bearing race (center of where the wear marks are to the end of the square taper is 36mm). On the non-driveside that same distance is 33mm. My over-all spindle width is 124.85mm and my shell width is 67.8mm. Do you know which sealed cartridge I should look to acquire? So far I have found 68 X 122.5 and 68 x 127mm only. Thank you.
