Based on KS's experience with the LEV Circuit, RAGE Circuit offers reliable performance at a price that makes wireless technology more accessible than ever.
RAGE Circuit is designed for riders who want the simplicity of wireless without sacrificing reliability and performance, all at an unprecedented price.

Total freedom from cables
Forget about wires and internal routing. RAGE Circuit is completely wireless, for a clean and minimal look on your bike.

Wireless, simple, and immediate
With RAGE Circuit, adjusting the saddle height is just a simple touch away. The proprietary KS 2.4 GHz wireless system ensures stable and responsive communication between the remote and the seatpost.
