E-bike and everyday riding

Enduro Pro Resin is an e-bike-rated compound for everyday trail, road and gravel riding. Use this pad shape only with the compatible calipers listed here, and match the complete brake setup to your bike and 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 Resin

An Enduro Pro option for riders who value braking feel on everyday trail, road and gravel routes.

The ratings describe the compound. They do not promise silent braking or a fixed service life, and they are not separate scores for each pad shape or caliper.

Compound ratings out of 10

These scores describe the friction compound.

Braking performance: 8
Fade resistance: 8
Heat resistance: 9
Lifespan: 8
Quietness: 8

Ratings from the supplied Enduro Pro compound chart. Higher scores indicate stronger performance in that category; a higher quietness score means quieter braking.

All curves shown

About this test

The horizontal axis shows rotor temperature; the vertical axis shows caliper temperature. At the same rotor temperature, a lower curve means a cooler caliper in this test setup. Consider this alongside braking power, pad life and correct fitment when choosing pads for long descents or heavier loads.

Indicative test comparison. Results relate to the tested samples and setup.

Compare against other brands

Compare braking power across compounds

All eight curves use the Shimano XT RT86 rotor. Choose a compound to highlight its tested result.

Why some curves stop earlier

Each test run stopped when the measured caliper temperature reached 120°C, the stopping threshold used to protect the piston seals in this test setup. The horizontal axis shows rotor temperature. Sintered’s shorter curve means the caliper reached the limit at a lower rotor temperature.

About this test

This chart compares braking power for bedded-in pads, all tested with the Shimano XT RT86 rotor. The horizontal axis shows rotor temperature (°C); the vertical axis shows braking power (W). Each curve represents the compound and backing-plate configuration named in the selector. Compare curves within their plotted ranges; no result is shown beyond the end of a curve.

Follow Enduro Pro Resin Black for this compound. This chart compares braking power against rotor temperature.

Test context: All pads shown can be good choices for their intended use when correctly matched to the bike and rotor, installed and bedded in. A lower or shorter curve does not by itself make a pad a poor everyday choice. Real riding temperatures depend on the route, total load, braking technique and setup; this test does not establish a temperature limit for the average rider. Rotor choice can substantially affect braking power, but these results apply to the tested combinations. This comparison does not guarantee the same improvement on another bike or identify one best pad for every rider.

Your questions

About these brake pads

Fitment, materials and performance explained.

What do the performance ratings describe?

The ratings describe the Enduro Pro Resin friction compound. Individual pad shapes, backing plates and calipers have not been separately scored. Higher scores indicate stronger performance in that category; a higher quietness score means quieter braking.

How do I check that these pads fit my brakes?

Match the exact caliper model and existing pad shape to the compatibility table on this page. Do not rely on the brake lever name or series alone. Check the front and rear calipers separately, because some systems use different pad shapes at each end.

Which rotors can I use with this compound?

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 the rotor’s condition and minimum permitted thickness before fitting new pads.

Do new brake pads need bedding in?

Yes. Follow the installation guide and complete the recommended bedding-in procedure before demanding riding. Bedding in prepares the new friction material and establishes an even transfer layer on the rotor.

Can I use these pads on an e-bike?

Yes. Enduro Pro Resin is an e-bike-rated compound for everyday trail, road and gravel riding. Use this pad shape only with the compatible calipers listed on this page, and match the complete brake setup to your bike and total load.

What is included in one pack?

Each pack contains 2 brake pads and 1 pad spring for one compatible caliper. Check the front and rear calipers separately before ordering two packs.

5* Absolutely fantastic brake pads, tonnes of stopping power even in heavy rain, highly recommend.

Hi Luke, thank you for your fantastic review! We're thrilled to hear you're satisfied with the stopping power, even in heavy rain. Enjoy your rides!

Very easy process from start to finish

Hi, we're glad to hear the process was smooth for you! Thanks for choosing Gorilla Brakes.

Great stopping power and quiet in the dry. Not had chance to use them in wet conditions

Hi Steven, thank you for your fantastic review! We're glad you're happy with the stopping power and quiet performance. Hopefully, you'll enjoy them just as much in wet conditions when you get the chance. Cheers for choosing Gorilla Brakes!

I’ve been using Gorilla brakes for a while now, really good pads no nasty noises and work perfectly

Hi Paul, thank you for your kind words! We're thrilled to hear you're happy with the pads and their performance. Thanks for choosing Gorilla Brakes!

Used Gorilla brakes for a while now, always had great service, even contacted me on one occasion when I ordered different pads than I usually use by mistake, checked the order and advised me to switch pad type. Excellent delivery times and great pricing. Highly recommended.

Hi Sean, thank you so much for your kind words! We're thrilled to hear you're happy with our service and products. Feel free to reach out anytime. Happy riding!

Excellent pads. Delivered Quickly!

Hi there! Thanks for your kind words. We're glad you're happy with the pads and quick delivery. Enjoy your ride!

Excellent product

Hi Paul, we're thrilled to hear you're happy with the product! Thanks for your support and for sharing your feedback.

Not great so far. Started to ‘squeal’ after only 10 miles

I bought a set of these pads for my summer bike and they were so good I've bought another set for my winter bike! I had glazed my Shimano brake pads and no amount of sanding would bring them back to normal. They felt Woody and lacked any stopping power. Switching to these gorilla pads has returned the performance to the best it's ever been and the lever feel is amazing!

Hi Mark, we're thrilled to hear how much you love the Gorilla Brakes! Thanks for trusting us for both your summer and winter rides. Happy cycling!

They work quietly and effectively

Hi Duncan, we're thrilled to hear that you're satisfied with the quiet and effective performance of our Gorilla Brakes! Thanks for sharing your experience.

Good quality pads, arrived the day after I ordered them

Hi there! Thanks for your great feedback. We're glad you're happy with the quality and fast delivery. Enjoy your ride!

So far, so good. I ordered these be a use my existing Shimano pads had a terrible squeal that I couldn’t get rid of. The new brake pads stop well without the squeal.

Hi John, we're glad to hear the new brake pads are working well for you and eliminating that squeal! Thanks for sharing your experience with Gorilla Brakes.

Good value brakes as replacement to Shimano brand

Hi Charles, we're glad you found our brakes to be a good value! Thanks for choosing Gorilla Brakes for your replacement needs.

Great at not fading, but they’re absurdly loud, whether cold, warm, or hot. This is with new brake discs and I followed the break-in directions. I’ve used semi-metallic brake pads before that were not even nearly this loud. Maybe 25%, and only if the discs got hot. It was useful for the race to let people know where I am from 1 km away (seriously), but I have to take then off for regular riding because it’s obnoxious.

Hi David,

Thank you for taking the time to leave your review, and we’re pleased to hear the pads delivered the fade resistance you were looking for.

The noise, however, isn’t something we’d expect to be caused by the brake pads alone. Brake squeal is almost always the result of vibration resonance somewhere in the braking system. Even with brand new rotors and a correct bedding-in procedure, factors such as caliper alignment, piston movement, rotor design, brake fluid condition, or the interaction between a very hard metallic compound and certain brake systems can create significant noise.

Some brake and rotor combinations are much more sensitive than others. We’ve recently developed new compounds specifically because we found certain brake systems perform better with a slightly different friction material while still maintaining excellent power and heat management.

Please get in touch with us directly. We’d be more than happy to help diagnose the issue and, if your brake setup would benefit from a different compound, we’ll happily exchange the pads or arrange a refund, even if they’ve been used. We stand behind our products and want you to have brakes that are both powerful and quiet.

Very good pads super fast delivery

Thanks we try our best

Prompt delivery, good service, the pads work fine

Hi Ian, thanks for your kind words! We're glad the pads are working well for you. If you need anything else, just let us know!

Arrived next day as promised. Fitted immediately and working perfectly

Hi John, glad to hear the pads arrived quickly and are working perfectly! Thanks for your awesome review.

Now, whether I’m an idiot or not I can’t be sure; I ride a Cannondale Topstone Carbon with Shimano GRX400 brakes. Is it me but those pads are not compatible with those brakes (‘was sure they’re listed as such).

The pads are in contact with the rotor (pistons are fully retracted).

Hi James,

Sorry you’re having trouble with the fitment.

We have tried to give you a call so we could talk this through properly, but we haven’t been able to reach you yet.

You have purchased the Gorilla Brakes NRS ONE pads. On these pads, the spring is built in as one piece,

If the pads are sitting in contact with the rotor, the spring may need opening up slightly before fitting. This adds more tension and helps the pads sit back from the rotor correctly.

Please remove the pads and gently open the spring section out a little, then refit them and centre the caliper over the rotor.

GRX brakes can also suffer from corrosion or build-up around the pistons, so it is worth checking that both pistons are moving freely and returning evenly.

give our workshop a call on 0800 772 0937 and we’ll talk you through it.

Kind regards,
Lee
Gorilla Brakes

The standard ultegra brake pads were good, the new Gorilla pads are definitely an immediate upgrade. Still bedding in, been through a couple of really wet weeks and never felt like I didn't have brakes

Hi Bob, we're thrilled to hear you're enjoying the upgrade with our Gorilla brakes! Staying confident in wet conditions is exactly what we aim for. Thanks for sharing your experience!
