Kris Holm Spirit Dual ISIS

R1,800.00

Strong. Light. Disk brake compatible. Spirit disk cranks are a result of a effort to develop the highest possible strength to weight ratio and pedalling performance in a unicycle crank.

Spirit disk cranks allow installation of a standard disk brake rotor (not included) to the right hand crank. This enables the rider to install a disk brake and maintain an efficient pedalling stance, minimal weight and the strongest possible wheel geometry. The rotor attachment is hardly noticeable for riders choosing not to use disk brakes. All cranks have double pedal holes for versatility.

OddWheel Info:

CRANK LENGTH:  To determine the crank size, measure the distance from the centre of the axle hole to the centre of the pedal hole. The smaller the ratio of the crank length to wheel size the faster the unicycle will travel, the larger the ratio the more control the unicycle will have.

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 maneuverability.
