The Tech 4 E4 represents the culmination of over 25 years of expertise in crafting hydraulic brake systems. It introduces a host of innovations, including new internal seals that minimize friction and a pivot mechanism that employs roller bearings. These advancements enable a lower spring rate, resulting in a lighter lever feel that diminishes rider fatigue while maintaining our renowned precision and control. Additionally, the upgraded E4 caliper incorporates hybrid-style stainless steel pistons augmented with phenolic inserts. This design facilitates smoother piston movement and reduces maintenance requirements. Even under extreme conditions, the caliper effectively manages high temperatures without experiencing heat transfer issues, ensuring optimal performance. 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 to improve ergonomics.– 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.– Complete brake available in Black or Silver with colour accent options of; Black, silver, purple, red, blue, or orange.– Choose either standard or braided hose (braided hose is an extra cost).– 30% pressure increase compared with the Tech 3 brake.– Reservoir area increased to lower overall stack height.– Shifter integration has been improved and now offers 30deg 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.– All Tech 4 brakes are supplied with new racing compound pads. For more information on all our pad compounds see the new pad guide here.– Maximum Rotor thickness for E4 caliper 2.3mm.
