Turbine is the most concave flat pedal designed for climbing, mobbing descents and tackling the most demanding terrain where riders are all-in on grip. Covered by a Lifetime Warranty inclusive of crashes and available in seven colors. The most locked-in feel you can get on traditional flat pedals, for when good grip just isn't good enough.A concave pedal gives riders a locked-in feel by cradling your foot in a "pocket" created by the platform. Turbine is designed with concavity in all ways front to back, inboard to outboard. With the added grip from the pins, riders can pedal and descend with a more locked-in feel than everAsymmetric pedal platform follows the anatomical shape of a foot wider at the front than the back giving maximum support, pin contact and grip. This platform shape also offers slightly better clearance and a better chance of deflecting off ground objectsSimple, well-proven internal architecture (with a bushing on the inboard side and bearing on the outboard side) means Turbine eliminates the bearing bump usually found next to the crank threads. Riders get a larger effective platform and can place their feet closer to cranks for better pedaling ergonomics6061 aluminum body with 6mm steel pins and chromoly steel axle115 x 110mm platform with 11 height-adjustable pins per sidePlatform thickness of 20mm at the edge with 3mm of concavity at the centerIncludes 4 spare pins and 44 pin washers for height adjustmentItem SpecificationsColorBlackDefined ColorBlackPedal Body MaterialAluminumPedal Spindle9/16"Pedal TypePlatformSpindle MaterialChromolyWeight419 RaceFace Turbine Pedals Pedals UPC: 821973491721
