Carbon Light Sole

Carbon fibre and nylon: an effective solution for demanding cyclists who require high performance with very low weight. Speedplay pedals compatibility using the specific adaptor.

NW Speedplay Adapter

The shortest distance between foot and pedal on the market. Northwave developed and patented in collaboration with Speedplay an exclusive adaptor that provides maximum power transmission on pedals thanks to the reduced thickness of just 05 mm rather the 3 mm of the traditional Speedplay adaptors. Made of nylon with a thin aluminium plate (it saves 85 gr) it respects the natural anatomy of the sole keeping a minimal distance between the foot and the pedal in any position.
Without adding bulk or weight that you find in systems without the adaptor.

S.L.W 2

Maximum precision and usability. The side button offers dual functionality: press the button for micrometric release or lift the button to instantly undo the shoe completely.
The ergonomic shape of the ratchet base matches the shape of the foot for added comfort while the size and minimized weight plus the outer soft-touch covering make it easier and better to grip. It features wires that harness the best technologies used in sailing and can be easily replaced using the spare parts kit.

Integrated Heel System

The new unibody construction of the uppers allowed to integrate an efficient hell retention system inside the structurewithout the need of external elements. Same efficiency reduced weight.
