Choosing Factory Racing Organic

Factory Racing Organic puts braking feel first for dry XC, road and gravel riding, with a quieter, responsive bite. This compound can wear very quickly in wet and muddy conditions.

All Enduro Pro and Factory Racing compounds are e-bike rated. For heavy cargo, loaded touring and demanding descents, we recommend Enduro Pro Ultimate Orange or Enduro Pro Semi Metallic Blue in the correct fitment.

HAYES Disc Brake Pads – Gorilla Brakes Factory Racing Organic FAQs

A little help with fitment, compounds and getting ready to ride.

How do I select the correct pad for Hayes?

Separate Dominion A2/T2, Dominion A4/T4 and the individual legacy Hayes fitments. Use the complete caliper name and compare the old pad outline. Check the selected product’s exact compatibility before ordering.

When should I consider Factory Racing Organic?

Factory Racing Organic puts braking feel first for dry XC, road and gravel riding, with a quieter, responsive bite. This compound can wear very quickly in wet and muddy conditions.

Can a compound guarantee silent braking?

No. A quieter braking character is a reason to compare compounds, but rotor condition, contamination, alignment and bedding in also affect noise. Choose the right fitment and follow the setup guidance.

How should I prepare the rotor and bed in new pads?

Check the rotor’s condition, wear limit and permitted pad material. Follow the installation instructions for your caliper and our bedding-in guide, including rotor preparation when changing compounds.
