Rear Brake HOPE TECH 4 EVO GR4 Silver/Silver

The HOPE TECH 4 EVO GR4 brake represents the pinnacle of British technology and craftsmanship. Engineered to provide perfect feel and total control, it represents the ultimate evolution of the renowned Tech 4 system. Fully CNC machined from a solid billet of 2014 T6 aluminium, it combines precision, power, and reliability to meet the demands of the most extreme riding disciplines, especially downhill and e-bikes.

The TECH 4 EVO master cylinder benefits from significant improvements: a new piston, floating head, optimized cam, second guide bushing, and three new levers. These developments deliver smooth, customisable control over braking power. The lever pivot runs on two sealed cartridge bearings, ensuring a smooth and consistent action, while the adjustment dials allow for fine-tuning reach and bite point to suit rider preferences.

The GR4 calliper, with a standard Post-Mount (74.2 mm), is one-piece CNC machined for increased stiffness and controlled weight. Its four hybrid pistons — two 17 mm and two 18 mm — ensure maximum power and optimal heat management. This model delivers 6% more power compared to the Tech 4 V4, while maintaining exemplary modulation. Ideal for gravity and electric bikes, it remains incompatible with vented rotors.

Supplied with three pad compounds (Racing, All-Conditions, and E-Bike), the HOPE TECH 4 EVO GR4 adapts to any riding style. With its 2 m hose, 14 colour combinations, and sophisticated design, it establishes itself as the ultimate benchmark in high-end braking for the most demanding riders.
