I am able to walk, and ride my bikes because of Titanium, I had a bad accident and my pelvis was broken into multiple pieces, on arrival at the hospital and after xrays ,i was told it was unlikely i would ever walk again. But a world renown pelvic specialist heard of my case and took it on(it was filmed and used for his North American lecture tour), the operation lasted 27 hrs and my pelvis is held together by several specially shaped plates and 20 plus screws(all Titanium), My Xrays looks like they are from Steve Austin the bionic man, they didn't stitch me up they stapled me, it was horrific at the time. Although I'm OK now I ride an Ebike because it can only take so much pressure. Obviously I love Titanium and when i can afford it I intend to get a titanium frame and build a super ebike around it. Titanium is my favourite metal for obvious reasons.

As the original owner and founder of Titus titanium Cycles I found your article to be pretty accurate. The the only other item you missed was the fatigue life of titanium is much higher than that of steel or aluminum. We warrantied our bicycles for life to the original owner when the aluminum frames were warrantied for one year and the steel frames for 3 years. We never had a failed titanium frame come back to us be due to fatigue. Now in a strange twist of fate, I find myself currently producing carbon fiber aircraft parts . Go figure . Good job on the article.

I bought a Merlin with lifetime warranty in 1990. I averaged 7000 miles per year through 2003 and had to replace the frame three times under warranty. Each of the first three frames developed cracks at or above the seat tube to bottom bracket weld after between 12000 and 35000 miles. I still have frame #4 but it only gets about 50 miles per week now.

I've had a Lynskey Ti bike for about 5 years and as Simon indicated it's extremely durable and immune to the effects of oxidation and the elements. I can't make any whacky fan-boy claims as to its ride comfort in comparison to other materials (that's really a function of your tires) but I do feel safer knowing that my frame won't crack due to stress as I've experienced on carbon bikes (and I'm not a big person). For me the bottom line on Ti is that the frame will outlast me, it's safe, it's seriously lighter than my steel bike, it always looks great in its raw, unfinished state and is totally repairable if it does get damaged. I'm not a missionary of titanium but if you decide to go this route there are no downsides and you can pass it along to the next cycling generation in your family.

Here’s an ironic fact: during the Cold War, the Soviet Union had the largest stock of titanium so the United States secretly purchased its titanium for the SR-71 from the USSR... they unknowingly helped America build the planes that spied on them!

titanium.The Queen of bumpy roads or cobblestones. Nothing to compare with,always stays in the same stiffness and doesn’t rust or oxydize and has that special shiny glance to it

Has to be one of the best deliveries I have encountered. Wish you had presented MOST of my mechanical engineering courses, I would have learned, not have left college wondering if I actually learned something! VERY GOOD!

After a few years of racing on a carbon bike, I made the switch this year to a custom titanium bike and I can safely say I am delighted! The feel on the road is pretty similar to what I had with my carbon bike with maybe a boost in stiffness and a clear boost in comfort. And yes indeed, beauty is subjective, but I just love the look of my new bike, the artisan managed to make seemingly seamless welds and the magnificent paint job just make it look so slick!

The bike in the background was stunning😊

I've been making heading (forging) dies for titanium fasteners for over 30 years and never knew so much about 6AL4V as I learned watching this video. Very concise. Thanks for making this vid.

1:45 The video states: "Both [3/2.5 and 6/4] have very high Young's Modulus." As a general rule, modulus is unchanged from minor alloying, so pure ti, 3/2.5, and 6/4 will all have about equal modulus. Ti has a modulus a bit over half of steel, so I wouldn't say it's "very high." It's definitely stiffer than aluminum, wood, plastics, etc., but it is far less stiff than steel or carbon.

I have a ti Kona King Kahuna (2000). The parts have changed numerous times, but the frame is still going strong. It's been ridden all over the western US (mostly the pnw) and on many DH courses and has never failed me. It's by far my favorite bike. It has a snappy ride quality, but is not harsh at all. If I had to pick just one bike to keep, that would be it.

Finally something about the frame that really last: Titanium. Please cover more information about it.

Very nicely done, sir! Great pacing and cadence, great data presentation and relating it to practical matters, and a very positive overall demeanor. Bravo, mate!

My profile pic is my Litespeed T1 and I absolutely love it. It has a 6Al top tube, but all the rest is 3Al and feels buttery smooth, especially with the Campagnolo Chorus groupset, and Bullet 50s (steel bearings). I bought the groupset off Wiggle, then assembled it myself. The frame weighed in at 980g before anything was put on it. I had a Specialized Tarmac which was a really nice carbon bike, but there is just something I cant pin down with titanium. Maybe it is because I dont have to worry about corrosion. Maybe it is because titanium virtually eliminates road buzz. Maybe it is because not many people have titanium bikes near me. Maybe it is because I dont have to worry about pretty paint. I accidentally leaned my bike against the sharp corner of a cement pillar and it slid along it a little and I could hear the grinding. At first I was worried, but then I just laughed because I can take a green Brillo pad and make it shiny in a few minutes. Go on. Give titanium a try. You'll thank me later, I promise.

I bought a Litespeed Catylst back in 1994 tricked out with 8 speed Dura Ace and a set of Mavic GEL 280 32 spoke tubular wheels! Very lite bike in that era about 18lbs./8.064k I turned it into a gravel bike, the Dura Ace brakes back then are wider they accept up to 30mm tyres!

I have a moots too, it truly feels alive when I ride it. I rented a carbon bike for an out of town ride once and it felt dead to me. The Aluminum frame I had felt to jittery, for lack of a better term.

Just as all carbon bikes are not the same, Ti bikes depend on the proper alloy in the right place, and expert manipulation of the tubes. I test-rode several Ti bikes in the early 2000's, and all felt dead until I tried a Litespeed Ultimate, with a mix of 6/4 and 3/2.5. 17 years later, and it's as lively as ever. Maybe the basic straight-gauge tubes have improved since then, but definitely try before you jump on a 'budget' Ti bike. Two years ago I rebuilt it with all new Super Record components, and built a twin carbon Litespeed (C1R) with the same components, wheels and geometry, so I'm able to compare apples to apples between the best carbon and the best Ti. While they feel quite different, I can't decide which I like better... but if I had to choose just one bike to keep it would be Ti. I view the carbon one as race-only, and only for TT and hilly road races at that, because it's lighter and more aero. For crits I'll grab the Ti bike 10 out of 10 times for its toughness. One crit crash and the carbon bike could be destroyed by a Ti bike. What's not mentioned in the GCN video is the fatigue life of Ti alloys. They make far superior springs than spring-steel due to lower hysteresis and much longer fatigue life. This flexing and returning nearly all of the spring energy is what gives Ti its life-long lively feel, similar to a good brand new steel bike, without getting whipped out in a couple years (or decades!) as steel does.

Love it when I learn something! Thank you!

It rips on the road with some slightly narrow tires, but takes everything you can throw at it on gravel or with a couple fully loaded ortlieb packs on the back. A Ti gravel bike with couplers is the true do it all, take it anywhere bike.

Have you looked into moots? they make some lovely titanium gravel bikes. I have a routt rsl it's the bees knees.

All the hard core cyclists I've met eventually end up on Ti. I would love to buy Ti but I can't quite afford it yet. Thanks.

I can listen to Si explain anything! Please do more lectures, preferably bike related :-)

I have an Enigma bike and i love it,very informative vid,cheers

It's just weird how alloys, with only a small percentage of different metals are so radically different than pure metals.

No it's not, you just have a very limited knowledge of science. You see it across all materials not just metals.

Metals tend to be naturally ductile when pure. Metallic bonding encourages this (the electrons are freely shared). Impurity atoms get in the way of the edge and screw dislocations, making it harder for them to propagate (which is how plastic yielding no-fracturing flow occurs)..This raises the yield point. Work hardening does this too but tends to be ineffective without alloying elements. The alloying elements affect the grain (crystal) size and the number of dislocations. The goal is to create lots of "dislocation pileups" where crossing dislocations "pin" each other. I haven't discussed the rather starkly different mechanisms by which small additions make such a difference specifically. In the case of steel, it is carbon that does the heavy lifting. Steel is literally an iron-ceramic composite material, where the ceramic is iron carbide (Fe3C). Another form of alloy hardening is called "precipitation hardening: which means something (an alloy element or intermetalliic compound) precipitates out of the solid solution as the working temperature falls to ambient. The nucleation if these precipitates create impediments to dislocation movement. Solid solution strengthening is even simpler. The dissimilar lattic dimensions of the two metals in solution create a stress that makes it difficult for flow to occur.

I'm hoping you know what GPa and MPa stand for. Using terms like Young's Modulus suggests you do. I would prefer you used the actual terms rather than the units for them. I don't have a kg or cm.

Excellent video. I chose to watch this video because I’m in the process of purchasing a light speed titanium bike on craigslist. Your video was extremely informative. It gave me the basic knowledge to know that I’m making a sound purchase.

Thank you for sharing the video. Any chance of explaining the various tube butting and welding (or brazing methods) to allow for more informed future purchases?

Simon... why why why... My Litespeed Teramo has been under the stairs for 5 years with a cracked seatstay... time to fix my favourite bike back to roadworthy condition. Titanium FTW.

I bought a "new" Litespeed years ago from the former PreOwnedBikes (which was like American Bicycle Group's certified refurb bikes). Cracked mine at the BB shell. They refused to warranty. Also bought a Tomac Taos at the same time, which was a great hardtail. Do a Google search of ABG titanium frames from that era and later on Lynskey frames...cracking seems pretty common with titanium.

Pretty much everything white has been dyed with titanium oxide. Not just paper as mentioned but plastics, paint etc. The problem is that enormous amounts of energy are required to turn titanium oxide into titanium so it will never be cheap. Aluminium is similar in that it only occurs naturally as bauxite but it is cheaper, less energy intensive to process.

My Ti Merlin Magia was built in about 2000. I'm at least the 3rd owner (had it 10 years). It has Shimano TL 24s and a Sram Force / Red groups (when is it going to get some love on the Tech show - photos sent weeks ago :-). Despite owning an S Works Roubaix with DA DI2, the Merlin is still my best bike. If only I could retro-fit it with discs. Also, fun fact: Titanium has a melting point of 1670 degrees C, so if your house burns down (and so long as the roof doesn't fall on it), your frame will be fine.

Dave Hughes drive feel is probably the most important part. Plus, youre finding the middle ground on all the other main materials. Lighter than steel, more comfortable than aluminum, tougher than carbon, and coorosion resistant. Might not be worth it to everyone, but I'd consider it for my next bike.

Lance Armstrong used a Titanium aerodynamic bike made by litespeed to win a TT in the 90s. It was re-painted to look like a Trek but it was a Litespeed.

Yep, Ti does zing and, in the case of my CX based models, on all terrain too! Well worth considering if you are not big into racing.

As a mechanical engineer it is funny to listen to these guys describe this stuff. GPa is a unit not a spec. The way he described the "GPa" would be like describing someone's cm as 182 instead of describing the height as 182 cm. I guess you can figure it out when there is only one parameter being discussed. But if you just said the bikes cm is 47 then how would you know which measurement he is referring to.
