Can I use other SRAM 1x11 shifters with 12-speed Eagle™? September 26, 2017 16:07 Updated No, Eagle™ drivetrains are only compatible with Eagle™ shifters, derailleurs, cassettes, chains and chainrings. Related articles What Eagle™ parts are cross compatible with existing 11-speed SRAM components? Can I use other SRAM 1x11 derailleurs with 12-speed Eagle™ cassette? Since the cable pull ratio is the same (X-Actuation) I should be able to use 11-speed X01 or XX1 parts with 12-speed X01 and XX1 Eagle™ parts right? Is the throw (distance) per shift different? I bought a new bike with SRAM Eagle drivetrain, but the B-Adjust tool for Eagle is missing. How do I adjust my derailleur properly? I want to build a MTB with drop bars for bike packing. Will my road shifter work with my MTB rear derailleur, or vice versa?
