Four-piston gravity brake for the most demanding applications.

Delivers maximum power with no compromise. Super-smooth lever action and premium construction make controlling that power feel natural. 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
