Description

The HOPE TECH 4 EVO GR4 brake embodies the pinnacle of British technology and craftsmanship. Designed to offer perfect feel and absolute control, it represents the ultimate evolution of the famous Tech 4 system. Entirely machined from a 2014 T6 aluminum block, it combines precision, power and reliability to meet the demands of the most extreme riding practices, including downhill and e-bike.

The TECH 4 EVO master cylinder benefits from significant improvements: new piston, floating head, optimized cam, second guide ring and three new levers. These evolutions offer fluid, customizable control of braking power. The lever pivot rests on two annular bearings, ensuring a smooth, constant action, while the adjustment knobs allow fine-tuning of guard and attack to the rider's preferences.

TheGR4 caliper, standard Post-Mount (74.2 mm), is machined in one piece for increased rigidity and controlled weight. Its four hybrid pistons - two 17 mm and two 18 mm - guarantee maximum power and optimum thermal management. This model offers 6% more power than the Tech 4 V4, while retaining exemplary progressiveness. Ideal for gravity and electric bikes, it is not compatible with ventilated discs.

Supplied with three types of pads (Racing, All-Conditions and E-Bike), the HOPE TECH 4 EVO GR4 adapts to all riding conditions. With its 2 m hose , 14 color combinations and highly advanced design, it is the absolute reference in high-end braking for the most demanding riders.
