Impact Groovy ISIS Cranks - 130mm (Black)

£136.25

A massive jump forward in the world of Unicycle cranks...

 

The Impact Groovy cranks are made from a single piece of machined aluminium to get the perfect round profile, without any joins or sharp edges. The Groovy cranks are the first cranks to have an integrated Rolling disc, which is part of the cranks design not added on top of the crank. When doing crank related tricks this design helps massively as there is nothing to snag or trap your feet.

Pedal washers go between the pedal and the crank, helping to increase the life of your cranks. Plus, ensuring maximum contact between both (keeping your pedals tight). We recommend pedal washers for all aluminium cranks.

Features:
Length: 130mm
Material: 7075 Aluminium
Finish: Hard Anodizing (Black)
Weight: 435g (including Rolling Discs)

Supplied with long M12 bolts.
