MK0 DEL Gravel Race Clipless Pedals are the lightest full-featured SPD-compatible pedals with a total weight of 174g. Extensive CNC machining is used to achieve the lowest possible weight while still maintaining excellent strength. They use a one-sided design for peak speed and consistent performance in gravel races. They feature a large platform for maximum power transfer and a connected feel that approaches that of a road pedal. The one-sided design features an open center between the binding cages for mud shedding. It has all the advantages of a road pedal, but with a shoe and cleat system that works in all conditions. The MK0 DEL Gravel Race Clipless Pedals have an adjustable Q factor of 4 mm increments. Inside the pedal is a stainless steel axle, three bearings, and two spacer. The spacers and bearings can be rearranged for Q factors of 51, 55, or 59 mm. This is simple enough for anyone to do at home. A spacer kit including four 2 mm spacers is available for purchase to further fine tune Q Factor adjustment.
