Magura Gustav Pro Disc Brake Lever

While the Gustav Pro is specifically engineered to handle the higher speeds and heavier weights of modern eBikes, it can technically be installed on any bike that supports post-mount calipers. However, its performance characteristics are optimized for high-load, high-power scenarios, so it may feel like overkill for a lightweight, non-electric mountain bike.

Magura has designed the Gustav Pro with a simplified bleed valve to make maintenance more accessible. While you will need a standard Magura bleed kit and mineral oil, the process is straightforward and significantly less cumbersome than previous generations.

The larger expansion reservoir is primarily there to ensure consistent pressure and prevent brake fade during long, heavy descents. You will notice a more reliable, predictable lever feel that stays firm even when the system heats up under the stress of a heavy eBike.

The Gustav Pro is designed as a complete system. We strongly recommend using the matching four-piston caliper to ensure the hydraulic ratios and performance characteristics function as intended.

This system uses Magura Royal Blood mineral oil. Do not use DOT fluid, as it will damage the seals and internal components of the braking system.

The four-piston design provides a larger contact patch and more even pressure distribution across the brake pad. This results in superior modulation, allowing you to control your speed more precisely rather than just locking up the wheel.
