Description

The Hope RX4+ is a high-performance hydraulic disc brake caliper designed specifically for road and cyclocross bicycles with drop handlebars. Drawing from a quarter-century of Hope Technology's experience in the brake industry, the RX4+ caliper is precision CNC machined from a single block of 2014-T6 aluminum. This monobloc design significantly enhances the caliper's rigidity, providing a firm and precise feel at the brake lever, reducing the sensation of a spongy lever, and minimizing brake pad friction when not engaged.

The caliper's slimline 4-piston design not only contributes to its lightweight profile but also ensures dependable and formidable braking power, crucial for the demands of road and cyclocross riding. Despite its strength, the meticulous CNC machining process allows for weight savings without sacrificing durability.

Recognizing the importance of maintenance, Hope has designed the RX4+ to be fully serviceable, promoting a long-lasting lifespan of the brake caliper. The top entry pad fitting streamlines the process of replacing brake pads, making it quick and straightforward.

This model is compatible with mineral oil brake systems, indicated by the 'M' on the bore caps, and is designed to fit flat mount standards, which are commonly found on modern road and cyclocross bike frames. It is versatile enough to accommodate rotors of 140, 160, and 180mm diameters, enabling riders to tailor their braking setup to their specific needs and preferences.
