The all-new Tech 4 V4 builds onHopes' 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 keepingHopes' legendary feel and modulation. The updated V4 caliper utilizes 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
• 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

**Please Note**
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 the2021 Commencal Supreme DH frame 200mm Direct Postmount
