SRAM EX1 Long Cage Rear Derailleur

The SRAM EX1 rear derailleur is designed for e-MTB, where a 11-48-tooth cassette and high torque at low cadence put the derailleur under stress. The design is based on X-HORIZON, which the manufacturer describes as providing precise, robust shifting. The aluminium cage and jockey wheels with steel bearings complete a construction designed for this use.

The colour is black. To choose, check the number of speeds in your drivetrain: this derailleur is 8-speed, with a maximum sprocket capacity of 48 teeth. The cable pull ratio is 1:1, so check that your shifter is compatible with this value.

Founded in Chicago in 1987 by Stan Day and a group of cycling enthusiasts, SRAM is still based in the US city today. It makes drivetrains and brakes for road, gravel and mountain bikes. Its story began with a single product: Grip Shift, the shifter that lets riders change gear by twisting the grip.
