This upgrade kit allows you to pair 11 speed mechanical SRAM shifters with a 12-speed Eagle™ derailleur and cassette. This is the neatest solution on the market, giving you all the performance advantages of a wide-range 1×12 drivetrain on a gravel, road or touring bike without the expense of electronic shifting
Front - You can fit this kit if your chain stay/seat stay cable stop is over 70 mm from the dropout. If it is under 70 mm from the dropout you’ll need the Rear kit.
Rear - Compatible with all frame routing variations.
