ZRACE XG4 Hydraulic Disc Brake Performance and Design
Four independent pistons deliver balanced clamping force across the rotor, ensuring predictable modulation during steep descents and high-speed cornering on any terrain. The full CNC machining removes excess material without weakening critical stress points, resulting in a brake caliper that weighs significantly less than conventional designs while maintaining structural integrity. ICE-TECH cooling pads dissipate heat rapidly during prolonged braking sessions, preventing fade when you need stopping power most. Flat mount interface integrates cleanly with modern road, gravel and fixed gear frames, offering universal compatibility with existing Shimano and SRAM hydraulic hose systems. The lightweight construction makes the ZRACE XG4 an ideal choice for racers prioritizing every gram reduction in their drivetrain assembly.

Great stopping power, i’ve paired these with some zrace rotors on some road wheels for my gravel bike. Couldn’t be happier.

First of all, the brakes work well, but I don’t know how to bleed them… The pressure doesn’t hold well with the gravity method.

I received the calipers, the color is just wonderful, the pistons are ceramic, i’m generally satisfied with the quality. although i haven’t installed them yet, i think this is one of the best solutions for flat mounts;)
