  • Low profile reduces weight and increases the likelihood of passing though tight passages unscathed
  • Single tension design keeps derailleur from hitting chainstay on bumpy trails and results in a smooth, quiet ride
  • Eleven-tooth pulleys run quiet and wear long due to alternating tooth contact between inner and outer chain plate
  • Direct chain routing reduces chances of a snag
  • High-tension return spring increases sensation of crisp shifting


  • Save 10%! This item qualifies for our drivetrain bike part discount. See Details
