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