Nimbus brand aluminium ISIS cranks. Lightweight and compatible with all ISIS hubs.
Cold forged aluminium cranks, as fitted to Nimbus Muni offroad unicycles.
Almost Zero Q-factor - This is the amount a crank bends outwards. Zero means it doesn't lean outwards at all. The straighter the crank the better for speed, the wider the better for ankle clearance and greater manoeuvrability. Crank length is measured from the centre of the axle hole to the centre of the pedal hole. Sold in pairs.
