Nimbus VCX ISIS Plus crank arms are deep pocket forged and CNC machined to optimize stiffness, strength and versatility covering the most popular crank sizes available. These are quite possibly the most versatile crankset you will ever own.
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.
Material: 6066 T-6 Aluminum.
Weight (pair): 454g
Pedal size: 9/16"
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.
