Factory pre-bled front braking from the Shimano GRX ST-RX825

The Shimano GRX ST-RX825 Disc Brake Set Front is built for gravel and adventure bikes that need complete, factory-ready front braking, pairing the GRX Dual Control lever with the BR-RX820 flat mount caliper as a pre-bled J-Kit. The RX825 lever brings GRX ergonomics built for gravel: a textured hood and lever blade for secure control on rough terrain, plus the reach and power adapted for long days in the drops.

This is the front assembly, featuring a left lever, the BR-RX820 caliper set for a 160mm rotor, resin pads with cooling fin, and a 1000mm SM-BH90 hose with connector insert already installed. The pre-bled J-Kit design means clean, consistent braking with minimal setup time, ideal for shops and builders who want reliable GRX stopping power without bleeding the system from scratch.
