I noticed after a long ride last weekend that the left crank was a little loose. I tightened it back up and rode again a few days later. Same thing after that ride. Loose. I took it off and tried blue loctite this time. I let it sit for a few days before riding the bike again.
Today while riding I noticed it was loose again, and when I looked down the crank was nearly off! When I stopped to inspect the crank it actually did come off then. I noticed some fine metal shavings on the crank bolt so I'm guessing the crank bolt threads have worn some or are damaged.
Am I down to replacing the spline and bolt? Would Teflon tape wrapped around the bolt help it stay in place? A friend suggested tapping the bolt threads with a hammer to flatten them and make it harder to turn, but I don't want to ruin parts that might still be good.
SRAM told me it was still under warranty as long as I had the receipt to show the bike shop. I don't think I have it so that option it probably out.
Crankset is a Truvativ Elita.
Any other ideas? Thanks!
