Hope Tech 4 Evo GR4 Disc Brake - Standard Hose

Discover the Power of Hope Tech 4 Evo GR4 Disc Brake

Building on the power of the incredible Hope E4 and V4 brake systems, Hope have honed and tweaked every millimetre of the new GR4 disc brakes to be even more power full, even more comfortable and even more rad!

With an all new lever design the smoothness of operation and power control is next level with a super light lever feel and power progression that gives ultimate control at the start of the lever throw and huge power at the end. The massive 4 piston calliper delivers all that power with ease whilst maintaining heat dissipation plus they looks cool as heck! The benchmark brake for Gravity and E-Bike use.

• New cam mechanism designed to decrease the free lever stroke while maintaining feel and modulation in the braking zone
• Piston movement – Additional secondary guide bush to keep the piston running perfectly straight to maintain super smooth piston movement. Bleeding –
• A bleed port has been added to the master cylinder body to allow bleeding without removing the lid.
• One piece machined caliper for reduced weight and increased stiffness
• Four hybrid pistons allow smooth movement and excellent heat management
• The largest pistons for the greatest power The larger pistons increase the ratio of the brake by 6% when compared to Tech 4 V4 brake system
• Improved caliper stiffness increases power and control
• Not compatible with vented rotors
• Revised bore cap design reduces width for more frame clearance
• Choose this caliper for ultimate power in the most demanding applications
