I'm trying to shed some more weight off my xc bike and I have a few questions about Titanium bolts. First and foremost, are they really worth it? Secondly, I cannot seem to find the ones I am looking for, so I am wondering if they even exist? What I would like is 6 or 12 Ti bolts to replace the standard ones used to mount the rotor to the hub/s on my avid's. Also, if they don't come in a set of 6 what individual ones will I need? Thanks for any help on this!
