Extention BB24 crank bolt

Crank bolt for Extention BB24 crankset.

• Made from 6061-T6 aluminium.
• Weight: 8.2g

This bolt is intended for bearing preload only and should only be tightened so much as to remove play from the cranks while allowing the cranks to spin freely. In order to avoid the bolt coming loose while riding it can be tightened further only after the bearing preload has been set and the left crank arm has been securely clamped onto the axle.

Trialshop.pl pro tip:

If cranks do not spin freely once play has been removed, loosen the crank arm, counterrotate the bolt by a few degrees and re-tighten the cranks. 

Should the cranks either be tight or have play, consider the following remedies:

• Possible BB bearing issues
• The frame's BB tube requires facing
