HOPE brake caliper RX4 + Flatmount FM Std for SRAM | DOT
For gravel bikes and racing bikes, HOPE has the right braking solution in its program, the tried and tested English milling art, paired with technical understanding led to the HOPE RX4 + brake caliper. The current version shines with larger pistons (2x 14 mm and 2x 16 mm to 2x 11 mm and 2x 14 mm), an improved angle of the brake line connection and new mounting options for the Flatmount standard.
Milled perfectly from solid, the RX4 + brake caliper in monoblock design not only leads to increased performance compared to two-part solutions, but also prevents unwanted chafing or "rubbing" with a better pressure point with the right pads and discs. Another advantage is the four-piston solution, with two smaller and two larger slave pistons. The two smaller ones lead to a quick application of the brake lining, the two larger ones maximize the braking force. This allows you to fine-tune the braking force even on difficult surfaces.
The HOPE RX4 + brake caliper fits all current hydraulic SRAM racing bike brake levers, the exchange is very easy, because you only have to swap your existing brake caliper for the HOPE RX4 + brake caliper. This means that you can update to the HOPE RX4 + brake caliper for all SRAM road bike groups (Red, Force, Rival and Apex).
Note: HOPE RX4 + brake calipers are only approved for the DOT 4 and DOT 5.1 brake fluid used by SRAM!
