Tech 4 V4 Disc Brake

The all-new Tech 4 V4 builds on Hope's 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 V4 caliper utilises hybrid-style Stainless steel pistons with a phenolic insert allowing for smoother movement and less maintenance, while still being able to manage high temperatures without heat transfer during extreme use.

• Key Features Increased power versus Tech 3 (30% pressure increase)
• 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
• Reservoir area increased to lower overall stack height.
• The Tech 4 retains the tool-free bite point and reach adjustments from the Tech 3.
• Hybrid-style pistons that allow smoother movement and require less maintenance, and a phenolic insert to manage heat transfer during extreme use.
• Rigid CNC'd one-piece caliper.
• 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.
• All Tech 4 brakes are supplied with new racing compound pads.

The V4 caliper is not compatible with all direct mount 180mm forks due to the large piston design and variation in mount positions. We recommend running the V4 caliper with the correct mount and a 200mm rotor in this application.
The V4 caliper is also not compatible with the 2021 Commencal Supreme DH frame 200mm Direct Postmount
