Pulse® WCS v2 Hubset

Hubs that equip the wheels of the same name, the Pulse® WCS v2 hubs are extraordinary hubs.

Third version, this one is further optimized in terms of quality and performance. This latest version changes its alloy from 7075 to 7050 for a small improvement in fatigue resistance.

The rear driver is now cold-forged before machining to improve the mechanical properties of the block. The groove of the labyrinth seal has been reworked to be more resistant and provide better sealing.

The rear axle has been completely revised and now offers ultra-simple bearing preload adjustment and does not require any tools for disassembly.

A new sprocket tightening nut, compatible with BSA bottom bracket wrenches.

Safe, reliable hubs requiring little maintenance and without the risk of stalling or loss of power transmission.
