Cam Mechanism

A new cam designed to decrease the free lever stroke while maintaining the feel and modulation in the braking zone — a key feature of the Tech 4 brakes.

The result is a slightly firmer feel at the bite point, followed by a gentle rise in power through the braking zone, further enhancing brake modulation.

Piston Movement

Roller bearing main pivot is carried over from Tech 4 along with sliding guide bush on the main piston. 

Additional secondary guide bush keeps the piston running perfectly straight to maintain super smooth piston movement throughout the full lever travel. 

Bleeding

A bleed port has been added to the master cylinder body to allow bleeding without removing the lid, simplifying and streamlining the process. The classic "open" bleed option is retained for the ultimate bleed.

The internal port design has been reworked to eliminate air pockets during bleeding and to support a more consistent bleed process.
