I bought a 2nd hand a SRAM gxp crankset that seems to be working itself loose. I’ve replaced the self extracting bolt as the threads were v badly damaged / largely stripped and it solved it for a time but then managed to get loose again, quick look inside shows some of the steel internal axle threads are a bit damaged too.
I’m thinking to check to see how deep the threads go, and if they extend far enough buy a longer screw for better thread engagement, and then use loctite instead of grease.
Should work.. or nah? Does anyone know the TPI of the screw? Looks like fine thread, think its diameter is m15
