The SRAM - Avid Brake Mounts are genuine hardware to allow you to fit various sizes or brake rotor on your frame or fork. Available in different options to suit both IS (International Standard) and the more common Post Mounts.

• Post Mounts bolt in towards your frame/fork.
• IS Mounts bolt in perpendicular to your frame/fork.

To work out what size you need:

• Check what size rotor your frame or fork is designed to natively accept (look up the specs)
• Check what size rotor you want to install.
• If you have 160mm mounts and want to run a 180mm rotor choose a 20mm increase.
• If you want to run a 200mm rotor choose and 40mm increase and so on.

Each option includes all the hardware you will need to install the mount.
