Hope Tech 4 EVO TR4 – The ultimate 4-piston trail brake offering the perfect balance of power, consistency, and control.
The Hope EVO TR4 is a four-piston disc brake designed for riders seeking the perfect balance of power, consistency, and control on varied terrain. Ideal for trail, all-mountain, and light enduro riding, it delivers a firm, consistent lever feel combined with perfectly modulated braking power.
The master cylinder incorporates EVO series technology with an optimized cam mechanism for shorter stroke and a more direct response, while maintaining exceptional modulation. Lever action is smooth thanks to the main bearing pivot and guide bushings, ensuring precise feel and fluid performance, even under heavy use.
Like the GR4, the TR4 offers three lever options (Standard, Power, Control) for personalized ergonomics based on your riding style. Each lever features a textured surface for optimal grip and allows independent adjustment of reach and bite point.
The one-piece machined caliper houses four hybrid pistons for powerful and progressive braking, while ensuring excellent heat dissipation. Designed for performance and reliability, the TR4 features a new integrated bleed port for simplified maintenance, while retaining the option of a full open-system bleed for advanced users.
