Titanium

Has anyone tried them and what is ti like for wear?

Pure titanium is extremely brittle. What is used in the bike industry is actually titanium alloyed with some other metal. Most parts in the bike industry made out of alloyed titanium will out last those of lesser metals. The trick is calculating the reduced wear as it compares to the increased price. You don't buy titanium parts to save money in the long run, you buy them because they are cool (although we on occasion use the excuse of shaving weight)........ I know, I have titanium parts on my road bike, I am much more skilled (at telling large stories) because of them.

So your saying its a waist of time and cash if i get a ti sprocket?

It will save roughly half the weight of the steel equivalent and, as Tim mentioned, will make you cool.

Wether it's a waste of cash is down to just how much cash you have really ;)

I have BMX friends who bent their Profile Ti spindle (for cranks), and one of them bent his Profile Kevin Porter Ti sprocket.

But why don't you get Ti spokes instead? They really last. My friend has it for 4 years already, and he trues them like once a year. Oh, he's not riding pure trials, old school street-trials to be exact, so his moves aren't those huge gaps and drops.

Stainless steel spokes last decades if they're built into a good wheel and not knocked off anything, same with titanium and aluminium though, once the material is kept below its fatigue limit (For steel and Ti) or kept pretty low on the s-n curve for Al you're not really going to see failures. If you're not going to titanium for the pimp factor and your bike isn't already as light as it can possibly be with steel sprockets, there's very little point bothering. If you have loads of spare cash send it to me - I'll find a way of spending it (Blackjack and hookers :P)...

Or you could buy this: http://www.chainreactioncycles.com/Models.aspx?ModelID=5157 - I've only heard of one person who's used it for XCing and it wore out a lot quicker than steel chains (I'm guessing because they're only using a crappy grade of Ti or not giving it the right heat treatment). KMC apparently do a 10 speed steel chain that's both cheaper and lighter than the Ti one however...

The Ti jet engine blades I've seen (And the reject blade I attacked with a hacksaw - sawed for about a minute before I made a noticeable mark, I was mostly polishing it with the hacksaw rather than cutting) are extremely hard wearing, so Ti can potentially be excellent in wear type applications.
