    Titanium rotor bolts?

    Has anyone replaced their disc rotor bolts with titanium one's?

    Ti yes, but removed them for fear of getting it out if it breaks. Im can think of other places to save weight

    Aluminum? No thank you. I like my bolt in one piece.

    Plastic? If you use plastic, then you are not smart enough to ride.

    Rotor bolts see way too much sheer stress to handle nylon bolts, and I don't think I'd trust aluminum either. Ti is done pretty often, but for me is way too expensive for the tiny weight savings for me to bother.

    A lot of high-end XC brakes have Ti bolts as standard.....Elixir XX, Hope mono mini, Formula R1 etc. I've run 3 Ti rotor bolts before, but no more. I've also run 6 alloy rotor bolts with no issues. My next trick will be 3 of each in alternating colours whilst juggling and singing the national anthem backwards

    I was tired of carrying around my uber-heavy house keys, so I sent away to Switzerland to have a new set machined out of titianium. It cost $300 dollars but it was worth it.... until I realized I could save another 2 grams by drilling teeny-tiny little holes all over them.

    Weight isn't everything though, I realized that the bulge in my pocket caused by my keys was slowing me down about 5 seconds over the course of a 3 hour ride. It's so hard to be aero these days! So I talked to the boys working down the street from me and payed em off to flatten my keys with their steam roller. The keys don't work as well anymore, but damn, I'm fast.

    ha ha, nice! Yeah for me light weight parts are probably more about perception than reality!

    To be fair, the weight saving really is minimal on these bolts, you could save the weight a number of cheaper and easier ways. However One major bonus particularly here in the UK is that the Titanium bolts stand up to the weather better so dont rust and seaze. Ally even alloy bolts tend to be one use wonders. You either strip the thread on the way in or damage the head on the way out.

    I thought I read somewhere that Ti fasteners in general require a specific prep or lube to keep from seizing? In the case of rotor bolts, is blue loctite adequate?

    Ti prep or anti seize can be used to prevent galling/seizing. But antisieze can give a false torque reading. Loctite would be okay as long as it prevents the Ti from contacting the aluminum in the hub.

    There are some weight weenies that run aluminum bolts.
