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. Kris Holm double hole cranks for Q-Axle axles have, as the name reveals, two pedal-threads allowing to change the ratio on your unicycle without changing the cranks.
- pair for Q-Axle-axles for maximum strength and stiffness. This spline 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.
- angled 8 mm outwards (Q-factor), which maintains a slim profile with just enough clearance to avoid bruised ankle bones.
- constructed from tough, stiff 7050 aluminum for all types of riding
- high polished aluminum silver
- 117/137mm
