Description

The Hope RX4+ disc brake caliper is the culmination of over two decades of Hope Technology's expertise in hydraulic brake design, tailored for road and cyclocross bicycles with drop bars. This caliper is a monobloc construction, precision CNC machined from a single block of 2014-T6 aluminum, which enhances its stiffness and provides a solid, responsive feel at the lever.

The slimline 4-piston configuration is not just lightweight but also delivers a powerful and reliable braking force, ensuring superior modulation and control. Its CNC machining ensures not only high strength but also a reduction in weight, making it an efficient upgrade for performance-oriented riders.

This caliper is fully serviceable, designed with longevity in mind, and aims to ensure an extended lifecycle of the product. One of the user-friendly features includes top entry pad fitting, which simplifies the process of pad removal and installation, saving time during maintenance or mid-ride adjustments.

The RX4+ is designed to be compatible with DOT fluid systems, characterized by the 'D' on the bore caps, and fits post mount setups common on many modern frames and forks. It is versatile enough to accommodate rotor sizes of 140, 160, and 180mm, allowing cyclists to choose their preferred rotor size based on their specific performance needs and bike compatibility.

Overall, the Hope RX4+ post mount caliper is an excellent choice for cyclists seeking a high-quality, performance-oriented brake caliper that offers precise braking control and the benefits of a meticulously machined lightweight design.
