FSA Crankset keeps coming loose

stuke · 2010-01-19T09:59:41+00:00

Anybody else have problems with the MegaExo style FSA chainsets coming loose? I've got the SLK carbon on my best road bike and every 100 miles or so I have to tighten the crankbolt back up. I've tried threadlock which helps but it still comes loose over time. Any suggestions?

I had the same problem on a Truvativ GXP MTB crankset. I think the interface is a similar piece of engineering. I have a nasty feeling that once the interface splines get worn by pedalling it when it is loose, then it never goes back together properly. I feel your pain!

I fixed it by replacing the crankset with a Shimano one.
