I’ve read some stuff lately that suggests shorter is better. But that author sells short cranks. As in 150. His theory is that longer cranks cause your hip to be impinged at the top of the stroke. Maybe. Most mountain bikers sit pretty upright anyway so I’m not sure it’s applicable. Many other small studies I’ve read suggest riders are most efficient at the crank length that they normally ride. I can’t find the link right now though. Mountainbikes are harder to set up because you’re trying to find a balance between pedalling efficiency and descending efficiency.
