I have a 2007 specialized roubaix with a sram gxp crankset, and the left side crank arm has started to become loose while riding. The research I’ve done on the internet suggests that the if the splines have worn down then that can cause the bolt to loosen. Has anyone encountered this and aside from using some loctite is it a fatal flaw?
It’s a fatal flaw even with Loctite. Chuck it.
