Rear mech
K-Force WE’s rear derailleur is a highlight of innovation. Unlike anything else on the market as it’s not a traditional parallelogram design, but a unique electronic-driven gearbox moving the cage across the cassette with immense precision.

Adopting this direction has enabled us to produce a more compact design where the motor works in perfect synchronicity with the lightweight mechanical arm, transferring motion with minimised opportunity for loss of accuracy.

A miniature yet tough gearbox is powered by the motor based on signals transferred from the shifters. Three gears mesh to produce lateral movement and ensure that the sides of the cage stay parallel. Carbon fiber is used where possible to reduce weight and maintain strength.
