Hope EVO Trial Zone No.9 Disc Brake

New cam mechanism designed to decrease the free lever stroke while maintaining feel and modulation in the braking zone
Piston movement – Additional secondary guide bush to keep the piston running perfectly straight to maintain super smooth piston movement.
Bleeding – A bleed port has been added to the master cylinder body to allow bleeding without removing the lid.

Two huge 25mm aluminium pistons offer great power and stiffness
Rigid CNC'd one piece caliper
Designed to work with our Trial Zone rotors for optimum performance
Complete brake available in Black, Purple, Red, Orange, Blue, Silver and Smoke
Postmount options available
Choose either standard or braided hose (braided hose is an extra cost)
30% pressure increase compared with the Tech 3 brake
Hydraulic ratio improved by using a small diameter master cylinder bore
Mechanical ratio increase for the best balance of increased power and modulation, resulting in usable lever feel throughout the full range of reach and bite point adjustment. The mechanical ratio has been fine-tuned using real riding data to provide its best efficiency at lever forces typically used during riding.
Linear relationship between brake pressure and lever force making it easy and intuitive to control the braking power.
Hinged clamp design to reduce weight and reservoir area increased to lower overall stack height. Shifter integration has been improved and now offers 30° of angle adjustment as well as neater packaging and compatibility with the latest shifters. Lateral adjustment on both sides of the master cylinder is also possible to give a wide range of lever position options.
The Tech 4 retains the tool free bite point and reach adjustments from the Tech 3

Only available with standard black hose

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.

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.
