Buy a set for each wheel

The kit gives you a "standard" and "CPS" set of spacers. Throw away the spacers you don't need. You will need to buy two sets if you have two identical brakes.

Nothing fancy, but they work great!

  • Familiarity: I've put it through the wringer

Few things are standard anymore and that goes for frame and fork specs or rotor sizes across the various disc brake options that are available. Use these kits to adapt your rotor size to your frame's specs.

These kits work great and include two sets of hardware so that you'll be set whether or not your brake calipers require CPS washers (many Avid's do). I ordered a couple of kits so that I could run a 160 mm rear rotor on a 140 mm post mount frame and also a 180 mm front rotor on a 160 post mount fork. The included instructions confirmed the correct location of all of the required washers and spacers so that I didn't have to guess.

My 2012 Specialized Stumpjumper HT is 140mm...

My 2012 Specialized Stumpjumper HT is 140mm post-mount rear with the 20mm spacers on it to work with the 160mm rotor/Avid Elixir 7s that came stock on the bike. I'm swapping the brakes out for Shimano XTs with 160mm rotors. Can I just continue to use the Avid spacers that are already on the post mounts? Do I need to get the Shimano-specific post-mount adapter?
