The Details

The SRAM EX1 8 speed rear derailleur is a world first. The first ever e-MTB specific rear mech, engineering to withstand the extra torque generated when riding with the power-assisted drive of an electric mountain bike.

The EX1 rear derailleur benefits from the technologies also seen on SRAM's top end XX1 and X01 mechs. This means you'll have lightning fast and accurate shifting and highly efficient chain retention.

  • Cage lock - With Cage Lock technology, wheel removal and installation as well as chain installation becomes faster and simpler
  • Roller bearing clutch - SRAM's roller bearing clutch derailleurs deliver maximum drivetrain stability in the roughest train, elimination derailleur bounce and chain slap without sacrificing precision
  • X-Actuation - Keeps shifting sharp and consistent across the whole cassette
  • X-Sync - SRAM's X-Sync pulleys and chainrings feature tall square teeth edges which engage the chain sooner than tradtional triangular teeth
