BB24 crankset as found on the Extention Heimdall bikes.
Spec:
As with all cranks used in trials and street-trials, extra care should be taken to ensure pedals are always tight. Riding with loose pedals may cause irreversable damage to the crank pedal threads. It is recommended to install pedals through a washer. If you do not have pedal washers and would like them included, please let us know in the comment section.
