Look’s new S-Track mountain bike pedals replace the Quartz with an entirely new design.
They use an “S” shaped spring, hence the name, that acts as a torsion bar and claims to provide instant entry and release regardless of conditions.
They come in three models, the base with a composite body and deflectors (142g), the S-Track Race with alloy deflectors and an injected carbon body (145g) and the S-Track Carbon Ti with the injected carbon body and titanium axle.
The deflector sits at the rear of the pedal and guides the cleat over as you slide your foot forward to clip in. Without it, the cleat would try to catch the rear spring.
Inside the oversized body there are two cartridge bearings near the threads and a needle bearing at the outer edge.
The cleats rest on a metal platform with 460 square millimeters of surface area. The sides are recessed a bit to provide clean ace for treads. They come with spacers for increasing the effective cleat height.
An optional cage doubles the surface area but will still let you clip in. It’s available in composite or alloy.
