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 andavailable 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 bushingon 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
