An incredible value in an off-road clipless pedal from Shimano! The M520 pedal features adjustable in/out release tension and includes a set of SH51 SPD cleats with 4 degrees of float. While they only weigh slightly more than the higher-end XT and XTR pedals from Shimano, they boast all of the same features and the same high-grade performance at a fraction of the price. These pedals will serve you well and wont break the bank. Dual sided mechanism lets you easily clip in with a simple step, without looking down at your shoes.
