Hope Tech 4 EVO TR4 Disc Brake - black/red

Our strongest brake with more braking power, controllability and better ergonomics through improvements in the reservoir and the newly developed, even more powerful GR4 brake caliper for a brutal transfer of braking power.

EVO TR4: 
Four-piston trail brake for medium-duty use.

The ultimate trail brake – impressive power combined with a firm and consistent lever feel. The super-soft lever actuation provides excellent braking feedback for absolute control.

Cam mechanism:
A new cam that reduces free lever travel 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 pressure point, followed by a smooth increase in performance in the braking zone, further improving brake modulation.

Piston movement:
The main bearing with roller bearing is taken from Tech 4, as is the sliding guide bushing on the main piston.

An additional secondary guide bushing ensures that the piston runs absolutely straight, providing an extremely even piston movement throughout the entire lever travel.

Bleeding:
A bleeding port has been added to the main brake cylinder housing, allowing for bleeding without having to remove the cap. This simplifies and speeds up the process.

The classic “open” bleeding option remains for particularly thorough bleeding.

The internal port design has been revised to avoid air inclusions during bleeding and to ensure a more consistent bleeding process.

Features:

• Lever with larger hook for more control and safety
• 2 retrofit options for the grip (POWER and CONTROL grips) for extreme preferences in lever widths
• Cam mechanism in the lever for even better controllability
• Bleeding port on the reservoir for convenient bleeding
• Larger brake pad for more contact area and better lever feel
• Revised design of the hole covers for a slimmer shape
