Shimano GRX ST-RX825 Disc Brake Set - Rear
Factory pre-bled rear braking from the Shimano GRX ST-RX825
The Shimano GRX ST-RX825 Disc Brake Set Rear is built for gravel and adventure bikes that need complete, factory-ready rear braking, pairing the GRX Dual Control lever with the BR-RX820 flat mount caliper as a pre-bled J-Kit. The RX825 lever delivers GRX ergonomics built for gravel: a textured hood and lever blade for secure control on rough terrain, with the reach and power dialed in for confident braking deep into a ride.
This is the rear assembly, featuring a right lever, the BR-RX820 caliper with a 25mm flat mount and no adapter, resin pads with cooling fin, and a longer 1700mm SM-BH90 hose with connector insert already installed to reach the rear caliper. 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.
