    Aluminum bolts

    Figured this may be the best section to ask in, since I know some people have replaced bolts with aluminum ones for weight savings. I am not really after the weight so much, I just want to pick up a few anodized bolts as highlights on my bike.

    I am trying to find out which ares are NOT suitable for aluminum bolts.

    So far, I have some aluminum ones for the water bottle cages, the brake levers, and the disc brake calipers to mount them to the frame/fork.

    I was looking at getting some for the stem (particularly the faceplate), and also for the sliding dropouts on my bike, but I wasn't sure if those areas would put them under too much force?

    Not the faceplate, if one of those breaks you could be in big trouble. Race Face warns against swapping out the high strength steel bolts to Titanium on their original Deus stems as they aren't up to the stress, so that should give you a head's up on the amount of stress that can be involved. Anything that doesn't involve high sheer loads or high tension loads can be OK for alloy bolts.

    Great, thanks for the info! Darn, even Ti isn't up to the job. That was my second choice (since I found some gold Ti bolts). Sounds like I should stick with the stock Thompson bolts.

    Will aluminum/alloy bolts be ok for mounting a disc brake caliper?

    Actually a lot of people do use Ti on their stems without issue. I wouldn't be too concerned about it.

    Most people use Ti, but you'd probably be OK with aluminum.

    I wouldn't use aluminum on a stress place like this.
    If you don't care that one day they can snap, go on, otherwise take titanium.
