Hope RX4+ Disc Brake

The Hope RX4+ is designed to be compatible with specific Shimano and SRAM road shift/brake levers. It is important to verify that your specific lever model is supported before purchasing, as the caliper is engineered to match the hydraulic leverage ratios of those systems.

Yes, the RX4+ is optimized for road, cyclocross, and gravel applications. Its flat-mount design and 4-piston architecture provide the consistent stopping power needed for mixed-terrain riding.

This caliper is designed to run on mineral oil. Please ensure your current brake system and levers are also compatible with mineral oil to avoid damaging the seals.

The top-entry design allows you to swap out your brake pads without removing the wheel or the caliper from the frame. You simply remove the pad retaining pin from the top, slide the old pads out, and insert the new ones.

A 4-piston caliper offers superior modulation and heat management compared to standard 2-piston road brakes. This is particularly beneficial for long descents, heavier riders, or gravel setups where you need more consistent, reliable power.

The package includes the caliper and the necessary hose fittings. You will need to supply your own brake levers, hydraulic lines, and mounting hardware specific to your frame.
