Description of Northwave Sonic 2 Carbon Road Shoe - 51 white/black
Sizzling performance for hot weather. An ultra-vented upper combined with a thermowelded multilayer construction, Carbon Light
sole and SLW2 dial closure is perfect for riders who need super breathability as well as stellar performance. The Sonic 2 Carbon road shoe is compatible with the Speedplay adaptor.
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.
It’s the Northwave ventilation system with large vents that lets your feet breathe: the lower vent channels air inside the sole, while the side vents guarantee a supply of fresh air.
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.
Multilayer Thermowelded construction:
New Multilayer construction: a light microfiber is coupled with somo large thermowelded mesh vent inserts at the same thickness of a traditional monolayer. The result: better comfort and reduced weight.
Speedplay Adaptor (not included in the delivery):
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 0,5mm rather the 3mm of the traditional Speedplay adaptors. Made of nylon with a thin aluminum plate (it saves 8,5gr) it allows to respect the natural anatomy of the sole keeping minimized the distance between the foot and the pedal in any position. Without adding bulk and weight as it occurs in systems without the adaptor.
Integrated Heel System:
The new unibody construction of the uppers allowed to integrate an efficient heel retention system inside the structure, without the need of external elements. Same efficiency, reduced weight.
