While the XPLR rear derailleur was designed for use with the 12-speed 10-44T cassette, it will work with 12-speed 10-36T cassettes as well. The chain length and b-gap distance will be different between cassettes so be sure to check out the user manual for full installation instructions that are specific to your gearing choice. XPLR models are 1x only and are not compatible with a front derailleur.
