Tech 4 Evo GR4 Disc Brake - Braided Hose

Hope Tech 4 Evo GR4 Disc Brake - Braided Hose delivers uncompromising braking power and precision for gravity, enduro, and e-bike riders who demand control on the steepest descents. Built around Hope’s proven four-piston GR4 caliper and the refined Tech 4 lever, this setup balances maximum stopping force with a smooth, predictable lever feel that inspires confidence when the trail gets rough. The braided hose provides a firmer lever response and improved durability under heavy loads, making it a favorite for riders who push their equipment as hard as they ride.

Every detail of the Tech 4 Evo GR4 system is engineered for performance and reliability. The lever uses a roller bearing main pivot and guide bushes for precise, friction-free actuation, while the increased lever hook and dimpled surface enhance grip and control in wet or muddy conditions. A redesigned bore cap and cam reduce free stroke and overall caliper width for better frame and hub compatibility, keeping the system compact and efficient.
