## Description

Note: 1. If your crank arm is ovalized and keeps falling off. Replacing the bolt with keep the crank arm attached for a while but will eventually fall off. If this happens you will need a new crank arm. When the square taper is ovalized from wear, it will back out the bolt. 2. If your crank arm bolt is stripping, it is usually due to the bottom bracket axle threading and not the crank, in that case, you will need a new bottom bracket axle.
