Hope Tech4 E4 rear brake Black / Grey Standard hose Hope

The all-new Tech 4 E4 builds on our 25+ years of experience in the design and manufacture of hydraulic braking systems. The Tech 4 uses an all-new internal seal to reduce friction, and the pivot rotates on roller bearings, reducing spring rate.the lower spring rate in turn gives a lighter lever action, reducing rider fatigue and retaining our legendary feel and modulation. The updated E4 caliper uses hybrid-style stainless steel pistons with a phenolic insert allowing smoother movement and less maintenance, while being able to handle high temperatures without heat transfer during extreme use.

Key features

• More power than Tech 3
• Lever shape updated to provide a more ergonomic shape oriented to provide the best mechanical advantage when braking.
• Articulated clamp reduces weight and ergonomics
• Improved shifter integration for greater adjustability
• Tool-free bite point and reach adjustments
• Hybrid piston design
• Rigid one-piece CNC caliper
• Compatible with a wider range of current shifter options
• New Smoke color (dark gray).
• Choose standard or braided hose (braided hose is an additional cost)

Technical specifications

• 30% pressure increase over Tech 3 brake
• Articulated clamp design to reduce weight and increased reservoir area to reduce overall stack height.
• Shift lever integration has been improved and now offers 30° angle adjustment as well as neater packaging and compatibility with the latest shift levers. Lateral adjustment on both sides of the master cylinder is also possible to offer a wide range of lever position options.
• Hybrid-style pistons for smoother movement and lower maintenance, and a phenolic insert to manage heat transfer during extreme use.
• The Tech 4 retains the tool-free bite point and reach settings of the Tech 3
• All Tech 4 brakes come with new compound racing pads
