Tech 4 EVO GR4 Brakes No Rotor

Four-piston gravity brake for the most demanding applications.Key Features:New cam mechanism designed to decrease the free lever stroke while maintaining feel and modulation in the braking zonePiston 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 stiffnessFour hybrid pistons allow smooth movement and excellent heat managementThe largest pistons for the greatest powerThe larger pistons increase the ratio of the brake by 6% when compared to Tech 4 V4 brake systemImproved caliper stiffness increases power and controlNot compatible with vented rotorsRevised bore cap design reduces width for more frame clearanceChoose this caliper for ultimate power in the most demanding applications
