In normal riding situations/ pedalling, the crank stopper bolt should not be tightned. The bolt is supposed to apply pressure on the bottom bracket sleeve, and NOT straight to the crank axle. Please check your BB sleeve regulary on damages. We are not liable for any damages on the cranks due to the crank stopper system.
