Proven Performance

The thumb lever delivers superior modulation and feel compared to foot actuation through an MX boot, especially on braking bumps where the bike shifts under you—maintain weight on the right peg for better stability. In right-hand corners with foot out for balance, riders gain full rear brake access where stock setups provide none. This added control builds rider confidence across rough tracks, jumps, and technical sections without fatigue or position compromise.

Proven Feedback:
Early track testing and rider trials show consistent positive results—riders report it as a valuable “”tool in the toolbox”” for demanding conditions, with noticeable improvements in control and composure.

Installation:
Simple and user-friendly—bolt-on design with clear bleed access. Standard bleeding procedures apply; no special tools beyond basics required.
