I have a 2009 Trek fuel ex 5.5 that I put a bash guard on. I didn't even ride it that much last summer because of my 29er but the Truvativ bolts I use seem to fall out? They loosen up and then there gone! I went to the LBS and figured I would give them another try but this time with lock-tight. I really don't want to get rid of the bash guard but I am not spending all this money all the time on these bolts. What other bolts are out there that may be stronger or made of a harder metal?
