E-bike guidance

Enduro Pro Power is an e-bike-rated compound. Gorilla Brakes recommends its Enduro Pro and Factory Racing brake pad ranges for e-bike riding. Match the pad shape, rotor and complete brake setup to your bike and its total load.

Rotor compatibility

This compound is suitable for all bicycle disc brake rotor types, including rotors marked “resin pads only”.

Rotor diameter and thickness must meet your brake manufacturer’s specifications. Check rotor condition and minimum permitted thickness before fitting new pads.

Compound performance

Enduro Pro Power

Enduro Pro Power is a steel-backed compound in the Gorilla Brakes Enduro Pro range. In the approximate plot, braking power rises from about 1,150 W at 40°C to about 1,530 W at 310°C rotor temperature. These figures describe the plotted test setup, not a maximum power rating.

These are approximate readings from the supplied test images. Results describe the tested setup.

How to read these results

Power’s curves are excerpts from a longer run stopped when the measured caliper temperature reached 120°C, to protect the piston seals in that setup. The displayed curves end at the last supplied point, before that stop limit. The horizontal axis shows rotor temperature. Values are approximate readings reconstructed from the supplied images. Ultimate continued to produce braking power in its separate follow-up test.

These results describe the tested samples and setups. Compare the curves only where their plotted temperature ranges overlap.

Your questions

About these brake pads

Fitment, materials and performance explained.

Why is this compound called Enduro Pro Power?

The name reflects its strong, immediate bite from cold. As heat builds, the compound delivers a consistent, predictable braking response.

Which Shimano brakes use this L/K-Type Power pad?

This L/K-Type shape fits the GRX, 105, Ultegra, Dura-Ace and Tiagra calipers in the compatibility table, plus the specified XTR, XT/SLX flat-mount, road, CUES and Metrea models. Examples include GRX BR-RX400/600/810/820, 105 BR-R7070/7170 and Tiagra BR-4770. Check your exact model in the full table. This is a different shape from the Shimano four-piston Power pad.

What is included in each pack?

Each pack contains 2 Enduro Pro Power brake pads and 1 spring, enough for one compatible brake caliper. To replace the pads in two calipers, order two packs and check the correct fitment for each brake.

What backing plates do Power pads use?

Enduro Pro Power pads use steel backing plates. Choose the pad shape that matches your exact caliper model and check the full compatibility table before ordering.

How should I install and bed in the pads?

Check the exact caliper model and pad shape before fitting. Follow your brake manufacturer’s installation instructions, use the retaining hardware specified for your caliper, and follow the bedding-in guidance for your pad and rotor setup.

What do the Power test graphs show?

The graphs plot braking power, caliper temperature and coefficient of friction against rotor temperature using approximate readings from the supplied images. Power’s curves are excerpts from a longer run stopped when the measured caliper temperature reached 120°C, to protect the piston seals in that setup. The displayed curves end at the last supplied point, before that stop limit. Ultimate continued to produce braking power in its separate follow-up test.
