product description

Boundary cranks are the latest development from Kris Holm to produce the highest possible strength to weight ratio and pedal performance in a unicycle crank.

Constructed from tough, stiff 7050 alloy for all types of riding, Boundary Cranks use the Q-Axle micro-spline standard for maximum strength and stiffness.  The Q-axle micro spine is parallel (not tapered) and secures with pinch-bolts on the crank. 

This makes it easy to install and remove, without the wear and tear of a tapered spline interface. Boundary cranks are angled outwards by 8mm (Q-factor), which maintains a slim profile with just enough clearance to avoid bruised ankle bones. 

For geared, KH/Schlumpf hub riders, the crank shape is configured to enable easy shifting and avoid accidental shifts. The Boundary crank comes with two pedal hole options to suit different riding conditions and rider preferences.

Compatible with Q-Axle hubs including the Kris Holm Boundary hub. 

Weight384 g/pair.
