E-bike use

Factory Racing Organic is an e-bike-rated compound. 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

Factory Racing Organic

Quiet, responsive braking for dry XC, road and gravel. This ultra-soft organic compound prioritises braking feel. This compound can wear very quickly in wet and muddy conditions.

Scores are approximate readings from the Factory Racing Organic chart. They describe the tested compound; actual braking and wear depend on your brake setup and riding conditions.

Compound ratings out of 10

These scores describe the friction compound.

Dry braking: ≈8
Wet braking: ≈7
Lifespan: ≈6
Quietness: ≈9
Heat dissipation: ≈9

Approximate ratings out of 10 from the supplied Factory Racing compound chart. Higher ratings indicate stronger performance in that category; a higher quietness rating means quieter braking.

Compound testing

Factory Racing Organic: braking power

These pads use a steel backing plate. The ratings shown on this page describe the Factory Racing Organic friction compound.

The graph compares pad compounds and backing-plate configurations, all tested with the Shimano XT RT86 rotor.

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 the Factory Racing Organic curve. Its highest plotted output in the Shimano XT RT86 rotor comparison was approximately 1,200 W. Values are approximate reconstructions from the supplied graph. This result describes the tested pad and rotor setup, not a maximum power rating or a fitment test.

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?

Scores are approximate readings from the Factory Racing Organic chart. They describe the tested compound; actual braking and wear depend on your brake setup and riding conditions. These scores describe the friction compound. Individual pad shapes, backing plates and calipers have not been separately scored here. Approximate ratings out of 10 from the supplied Factory Racing compound chart. Higher ratings indicate stronger performance in that category; a higher quietness rating 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. Factory Racing Organic is an e-bike-rated compound. Use this pad shape only with the compatible calipers listed here, 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.

OK in the dry. In the wet still quite good to be fair. Will get some more.

Hi Clive, thanks for the great review! Brilliant to hear the pads are performing well in both dry and wet conditions. We really appreciate your support and look forward to helping you again.

Awesome stopping power, a noticeable improvement over standard.

Hi Mark, we're thrilled to hear you're enjoying the improved stopping power! Thanks for sharing your experience with the Shimano MT Series pads. Ride safe!

Really happy with the pads

Hi Jon, we're thrilled to hear you're happy with the pads! Thanks for your support and enjoy riding!

They were awesome. Noticeably better than stock and have held up well here in the descents of Utah.

Hi Miguel, we're thrilled to hear you're happy with the Shimano MT Series brake pads! Thanks for sharing your experience, and happy riding in Utah!

New pads are spot on for braking, only concern I have is when it’s wet brakes squeal like nails down a blackboard.
Not sure if it’s because they’re new, only Done 50 miles but still **** of a squeak in wet conditions.

Hi Dave,

Thanks for the feedback, and I’m glad to hear the braking performance is spot on.

With resin pads, a bit of noise in wet conditions can happen, especially when the pads are still quite new. At around 50 miles they may still be bedding into the rotor properly, and in the wet you can get a temporary squeal as water, grit and road film pass between the pad and rotor.

A few things to check:

Make sure the caliper is aligned correctly and the rotor is running clean through the pads.

Avoid using strong cleaners or bike wash directly on the braking surface, as this can interfere with the transfer layer on the rotor.

After washing or riding in heavy rain, do a few firm controlled stops to put some heat back into the pads and dry the system out.

The important part is that the pads are braking well, so it does not sound like a power issue. Wet-weather squeal is normally vibration rather than the pad itself being faulty, but keep an eye on it as they get a bit more use.

If it continues after a few more rides, send us a quick photo of the pads and rotor and we’ll take a look.

Kind regards,
Lee

Best brake pads i have ever used i had gorilla pads in the front and shimano in the rear i had massive brake fade 2 weeks ago in the rear wheel but the gorilla pads in the front held me all the way down those big hills for the rest of the day i have just fitted gorilla in the back brake plus they dont wear down half has much has most good brands they are worth the money

Thanks for a great reveiw

Racing stealth pads once bedded in they made a massive improvement over the standard pads very pleased highly recommend

Who would have thought that swapping out the OE pads would make such a massive difference?!

As soon as these weee bedded in (like, 5 mins tops) the braking was notably improved, I’d say 300% better! And on bog standard Shimano MT200 too. Really appreciated this next time out on the trails.

Lots of advice from the Gorilla Team beforehand and a huge amount of guidance and tips on the site too.

British firm too. Support our growing bike trade guys!

Definitely 5STAR,I ove it.

Hi there! We're thrilled to hear that you're loving our Shimano MT Series Enduro Pro Ultimate Disc Brake Pads. Thank you for taking the time to leave us a 5-star review, it means a lot to us. Happy riding! 🙂

Great quality pads.

The ceramic compound pads are very progressive and powerful, but they remain quiet in all conditions.

By comparison, under the same amount of lever's pressure, these pads stop you with the same power as Shimano sintered equivalent.

I found the pads reliable on trails, at the bike park and on XC courses.

Hi Emanuel,

Really appreciate you taking the time to leave this great to hear how well they’re working across different riding styles.

That progressive feel with strong, consistent power (without the noise) is exactly what we aim for with the Ceramic compound, so it’s spot on that you’re getting that both on trails and at the bike park.

Good comparison with the Shimano sintered too that’s a strong benchmark 👍

Thanks again for the support, and if you ever need anything just give us a shout!

Bought these to replace the expensive Shimano originals. They work better, are compatable with disc materials so no squealing and give you lots of power. Unless you weigh 100Kg plus and are going down Alpe d' Huez the heat dissipation seems just fine.
