The Impact Groovy cranks are made from a single piece of machined aluminum to get the perfect round profile, without any joints 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 as there is nothing to snag or trap your feet.
Weight is 435g (including Rolling Discs)
Material: 7075 Alloy
Color: Black hard anodising

Q-Factor: 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 maneuverability.
Note: Crank length is measured from the center of the axle hole to the center of the pedal hole. Sold in pairs.
