SRAM EX1 Long-Cage Rear Derailleur
Couldn't load pickup availability
The SRAM EX1 rear derailleur is designed for e-MTBs, where an 11-48-tooth cassette and high torque at low cadence put the derailleur under strain. Its design is based on X-HORIZON, which the manufacturer says delivers precise, robust shifting. The aluminum cage and pulleys with steel bearings complete a build designed for this use.
The only available version is black. To choose, check the number of speeds in your drivetrain: this derailleur is 8-speed, with a maximum capacity of 48 teeth on the sprocket. The actuation ratio is 1:1, so check that your shifter is compatible with this ratio.
