MK0 ALT XC Clipless Pedals feature an extra large platform area that maximizes pedal to shoe contact, creating unprecedented power transfer when compared to other XC pedals. Most SPD-compatible XC pedals only contact the shoe at the cleat and cage interface, which can feel like pedaling on a golf ball. MK0 ALT XC Clipless Pedals are lighter, feature more platform area, and have a thinner pedal body than the competition for maximum control, power transfer, and ground clearance. For MK0, Wolf Tooth doubled down on the ALT pedal design, leveraging even more aerospace materials, each optimized for weight savings, durability, and speed. Titanium axles and hardware, stainless steel bindings, and finely machined 6061 aluminum pedal bodies converge in a special blend of high performance witchcraft. Built with the finest components available for strength, durability, and weight reduction. Inside you&';ll find DLC-coated machined titanium axles, three low-friction cartridge bearings, and an igus bushing with a custom radial seal that protects internal components from trail debris Thin profile means a reduced chance of pedal strikes when cornering or riding over rocks and roots, and the open center quickly sheds mud that can interfere with clipping in and out to ensure that your clips and unclips are quick and reliable 6061-T6 aluminum CNC machined body and titanium axle with diamond-like carbon (DLC) coating Adjustable Q factor options of 51, 55, and 59 mm.
