We love the Hope Tech 4 E4 Hydraulic disc brakes because they offer maximum stopping power in a lightweight and sleek package. The E4 has 30 percent more power over the Tech 3 model. It has a durable construction, with the caliper being made of a one-piece, CNC-machined aluminum alloy and an aluminum lever, too. The lever features a tool-free reach adjustment and a bite point adjustment, so we can get the perfect lever feel and pad contact for our riding style. The lever is compatible with shifter standards for seamless integration, and the improved shape is more ergonomic to help with braking. The Tech 4 E4 has a hybrid piston design for smoother and more reliable movement, and a phenolic insert helps to dissipate heat on long descents.
