What's the benefit of using titanium skewer beside the fact that it's light? Is it strong enough to hold my weight?

I would say that the primary benefit is that it removes money from your pocket and puts it in the pocket of the manufacturer & retailer. –  Daniel R Hicks Feb 20 '12 at 12:24

Aside from weight, there is no real benefit. Titanium is an alloyed steel, and has no limitation on weight or riding style, generally, although there are likely ultra light versions which do have limits.

What do you mean Titanium is an alloyed steel? Are you saying that in the skewer it would be an alloy or are you saying the element Titanium is an alloy? –  Vincent Agnello Feb 22 '12 at 4:45

The material sold as titanium commercially is steel, alloyed with a small percentage of titanium, or the element titanium, alloyed with Aluminum and Vanadium to make it soft enough to work. In bicycles, it is actually the latter which is more common. –  zenbike Feb 22 '12 at 4:57

@VincentAgnello: "alloyed steel" is redundant -- steel is an alloy, it is not listed on the Periodic Table of Elements. Commercially available titanium is an alloy, the most common being Ti6-Al4V –  OMG Ponies Feb 22 '12 at 5:11

@OMGPonies: Exactly. Steel is always an alloy. Sometimes, the material sold as Titanium commercially is a steel alloy, which uses titanium as an alloying element. Does that make it more clear? –  zenbike Feb 22 '12 at 5:51

I have broken a

  • Ti stem that held my handlbars.
  • Ti seat rail
  • Ti frame (in 3 places now, alas)

So Ti is not magical, but this is on a 18 year old frame now, so not that surprising.

I have broken several axles, but steel ones have been sufficient for the last few years for me. I suspect weight is the only benefit, however when you care at the level of a few grams, it seems silly when a full water bottle weighs almost a kilo. (1 litre of water weighs 1 kilo)

so Ti is not that strong compared to steel one.. –  Rick Ant Feb 21 '12 at 1:22

@RickAnt: The density of titanium is nearly twice that of aluminum (though aluminum is the weaker of the two metals), but only 56% the density of steel. The stiffness of titanium is also about half that of steel. It therefore follows that the stiffness-to-weight ratio of the two metals is nearly the same. In English this means that titanium is nearly as strong as, but is lighter than steel. –  OMG Ponies Feb 21 '12 at 1:51

@RickAnt Nope, I was suggesting I am quite hard on bikes. :) I have broken steel frames, skewers, pedals, cranks, and more. Ti has worked MUCH better for me than steel. I just used to do a lot of mileage a year (8000K a year for about a decade) and am a big guy. –  geoffc Feb 21 '12 at 1:59

Geoffc: I would suggest this answer is more commentary than really an answer to the question asked. Not picking, but next time, maybe use the comment field. –  zenbike Feb 21 '12 at 6:57

The rear wheel (with a Ti skewer) on one of my road bikes would flex and rub against the frame when I stomped on the pedals or climbed a steep hill no matter how tight I made the skewer. I fixed the problem by switching to a steel skewer. No more flex and even the rear derailleur shifts better.

For skewers, weight. That's it. Ti skewers will make your bike and your wallet lighter.

Titanium alloys are typically made of Aluminum and Vanadium: e.g. on a 3AL/2.5V Ti bike Frames for instance there is 3% Aluminum, 2.5% Vanadium and the rest is Titanium.

Main benefits of Titanium is no corrosion, immense resistance to fatigue (material failure due to cyclic constraints), and weight indirectly (i.e. stronger material allows to use thinner tubing, for bike frames for instance).

Titanium parts are usually very very long lasting, mainly due to resistance to fatigue and corrosion.

Welcome to Bicycles SE. This site does not operate like a typical discussion board. It operates on a Q&A basis. Much of your post was commentary on other answers. Once you have asked and answered a few questions, you'll have earned enough reputation to comment everywhere on the site. In the meantime, I have cleaned up your answer to better fit our format. If I have removed anything crucial, feel free to edit it back in. –  jimirings Apr 20 at 12:06
    
@jimirings But this is a better answer than the accepted. The accepted answer incorrectly states weight only. This answer identifies corrosion and fatigue. –  Blam Apr 20 at 18:54
    
@Blam I didn't say it was a bad answer and didn't vote it up or down. I simply removed the portions of the answer that should have been comments on other posts so that it stands on its own. If you feel that I have removed something important, feel free to edit it back in. –  jimirings Apr 20 at 19:03
    
@jimirings Cool - good edit. Jacques is also commentary. –  Blam Apr 20 at 19:06
    
@Blam When you see posts like that, flag them. One of the mods will get it taken care of. –  jimirings Apr 20 at 19:19

Ti = really expensive = really light = usually racing parts = shortened lifespan due to the gram saving which actually weakens the parts for the long haul.

If you race and need every ounce shaved off and your sponser is paying then they're great.

If you don't race or are paying your own way then you'd be better off spending your cash on something meant for longer life and trying to skip that post ride beer to save on long term weight.

I don't agree that titanium has a shorter life span. It fatigues less than steel and does not rust. I commute on titanium bike. –  Blam Apr 20 at 10:10

It is light, and doesn't corrode. The skewer doesn't take weight at all - that is all held on the axle. The skewer just provides compressive force to stop the axle dropping out of the forks.

For skewers, other than weight and durability, one unmentioned advantage of titanium is its resistance to corrosion. Rusty steel skewers can get stuck inside your hub, forcing expensive replacement which is much less likely with titanium (you should still grease them though).
