Technologies

S.L.W.3 – The SLW3 system developed by X-Dial offers fast, micrometre-precise adjustment. The compact mechanism is easy to use: press the button to release the shoe step by step, or lift it to open the shoe completely at once.

MORPH carbon composite sole – An anatomically shaped sole with a stiffness index of 13, designed to balance comfort and performance.

SPEEDPLAY ADAPTER (optional) – Developed and patented by Northwave in collaboration with Speedplay, this adapter reduces the distance between the foot and pedal. It is 0.5 mm thick, compared with 3 mm for traditional Speedplay adapters. The adapter helps provide power transfer to the pedals. The nylon adapter with a thin aluminium plate is 8.5 g lighter. It adapts to the shape of the sole, keeping the distance between foot and pedal minimal in different positions, without the additional space and weight required by systems that do not use adapters.
