Hope RX4+ Road Brake Caliper

Hope RX4+ Road Brake Caliper

The RX4+ caliper is based on 25 years of experience in the design and manufacture of hydraulic disc brakes, transferring the knowledge and skills acquired to the world of brakes from mtb to cyclocross and road. A precision CNC machined monobloc design results in a stiffer caliper for unmatched feel and modulation.
The RX4+ calipers come in different models: a Postmount caliper, Flat Mount Front Direct calipers and Flat Mount Rear Direct calipers with the addition of a new Flat Mount caliper.

Calipers designed to fit 140, 160 and 180mm rotors
Slim and light 4-piston design
Monobloc design creates a stiffer caliper that reduces fuzzy lever feel and brake pad rub
Available in black, silver, red, blue, purple and orange
CNC machined from 2014 T6 aluminum
