Hope Tech 4 E4

The Tech 4 E4 builds on our 25+ years’ experience designing and manufacturing hydraulic brake systems. The Tech 4 uses all new internal sealing for reduced friction and the pivot spins on roller bearings, allowing the spring rate to be reduced. The lower spring rate in turn gives a lighter lever action, reducing rider fatigue and keeping our legendary feel and modulation.

The updated E4 caliper utilises hybrid style Stainless steel pistons with a phenolic insert allowing for smoother movement and less maintenance, while still able to manage high temperatures without heat transfer during extreme use. Increased power versus Tech 3. Lever shape updated to provide a more ergonomic shape orientated to provide the best mechanical advantage during braking. Hinged clamp reducing weight and ergonomics. Shifter integration improved for more adjustability. Tool free bite point and reach adjustments. Rigid CNC machining.
