Wolf Tooth DEL Gravel Race Clipless Pedals feature a one-sided design for peak speed and consistent performance in gravel races. These pedals are exceptionally lightweight at only 216g, while still featuring 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 DEL Gravel Race Clipless Pedals have an adjustable Q factor of 4mm 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 59mm. This is simple enough for anyone to do at home.
