Built for the most demanding rides, this four-piston gravity brake delivers uncompromising stopping power. The super-smooth lever action and premium construction ensure precise, natural control, making it the benchmark choice for gravity and e-bike use.
The Lever Blade
There are 3 different lever blade options.
- Brakes are supplied with standard (STD) lever blades, this blade will be the right choice for the majority of users and applications. POWER and CONTROL options are available separately.
- All EVO blades feature an increased lever hook for greater control and security during aggressive riding and a new dimple design in the finger contact area to improve comfort during hard braking, while still retaining grip in all weather conditions.
- All blades also allow reach and bite point adjustments.
STANDARD
A good balance of lever feel, power and adjustment range.
POWER
A profile tailored for users that position the lever further away from the bars, allows for 5mm more outward adjustment than STD. Increased length generates more mechanical leverage and compensates for lever position further away from pivot point.
CONTROL
Optimised for running closer to the handlebars, allows the blade to be adjusted 5mm further inwards than STD. Slightly shorter length helps to maintain lever feel with the change in biomechanics.
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.
