HOPE Tech 4 E4 rear brake black / purple

The Ultimate Enduro Brake. The new Tech 4 E4 is based on designing and hydraulic brakes. The Tech 4 uses an all-new internal seal to reduce friction and the lever rotates on bearings, minimizing work on the spring, resulting in a lighter lever action that reduces rider fatigue and maintains our modulation and feel. legendary. The updated E4 caliper uses hybrid-style stainless steel pistons with a phenolic insert that allows for smoother movement and less maintenance, while also being able to handle high temperatures without heat transfer during extreme use. Features: - 30% increase in stopping power over a Tech 3. - Redesigned lever design with a more ergonomic shape geared towards achieving a linear relationship between brake pressure and lever force, making modulation more intuitive. - Articulated clamp that reduces weight and improves ergonomics. - Greater integration with the shifter for a better fit. - Adjustment of reach and tension without tools. - Hybrid piston design - Caliper CNC machined from one piece. - Clamps compatible with a greater number of current Sram and Shimano gears. - Post mount mounting options. - Mounting options with PVC or metal hose.
