The Tech 4 E4 builds on Hope's 25+ year's 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 Hope's 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. Specification 30% pressure increase compared with the Tech 3 brake. Hinged clamp design to reduce weight and reservoir area increased to lower overall stack height.. Shifter integration has been improved and now offers 30° of angle adjustment as well as neater packaging and compatibility with the latest shifters. Lateral adjustment on both sides of the master cylinder is also possible to give a wide range of lever position options.. Hybrid-style pistons that allow smoother movement and require less maintenance, and a phenolic insert to manage heat transfer during extreme use.. The Tech 4 retains the tool-free bite point and reach adjustments from the Tech 3. Features 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. Hybrid piston design. Rigid CNC'd one piece caliper. Compatible with a wider range of current shifter options. Supplied with 1600mm hose so these can be used on the front or rear.
