The all new
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.

Tech Specs :
- 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
