    Normal for rack bolts to come loose?

    Just got back from a grocery run, and after unloading I went back to unstrap the U-lock and that's when I noticed that the rear rack was a bit loose. I'm thinking didn't it have a solid feel before? I then inspected the rack and nudged it here and there and soon found the problem. One of the bottom bolt that bolts the rack leg to the drop-outs fell off and the other one on the other leg was on the brink of falling off! I tightened that one back and for the missing bolt I got one of the two unused water bottle bolts.

    My question is this normal? I'm thinking the vibration must have done this. How can I keep them on snug and tight?

    Yup, it's just vibration. Things shake loose, it happens. Just tighten the bolts good and tight without bunging the heads and it should be fine. If it becomes a persistent problem, you could try some thread locking gunk like Loc-Tite but it probably won't be necessary.

    Yeah, I have trouble with them too. For some reason, they seem to me more vibration prone than any other bolts- no idea why. I now put Loc-tite on all of mine (brake bolts too) and use lock nuts on through-bolts. If you do that, just make sure you don`t use the super strength permanent stuff.

    It happens. I check my bolts fairly often, they're never loose, but I'm paranoid. If it becomes a problem, add just a drop of blue loc-tite.
