    Bolt Material Selection?

    I want to swap most of the bolts on my Scalpel with Ti and Aluminum.
    Since these two marerials have different strengths, where are the appropriate places to put the different material bolts?
    In other words, where do you use Aluminum, Ti, and Steel bolts?
    Hope this makes sense.

    I finally got around to figuring out what bolts I needed for my 2011 Scalpel.
    Just ordered $100 worth of Ti/Aluminum bolts from Toronto Cycles... ouch. : )

    The weight saving by swapping bolts is really that minimal that you should ask yourself the question if you've done all the other stuff that you could do that actually saves you more weight per buck.
    In case you have; I think it's simple: alu for all the non critical parts like cage bottle screws etc, titanium for parts that are important and depending on your riding style you might want to stick to steel for the really critical parts ;-)

    I hate to say it but the Ti stuff I got from china was pretty good end reasonable. I have'nt got the curage to try any of their "critical" stuff yet

    I just snapped-off an aluminum rotor bolt in the hub. (Expletive)
    I'm installing 3 Ti and 3 Alu. I was using my Ritchey 5nm key. What torque should the aluminum bolts be?

    A 5mm aluminium bolt would likely be under 3Nm max torque, but it will depend a lot of how the threads are cut, rolled threads will likely be a bit stronger than cut threads. Really alloy bolts shouldn't be used in any situation where they are being torqued. They are better suited to things like lever clamps and water bottle bolts where they just have to be snugged up tight,
