Shimano Deore M591 10 Speed Shifter Units

The Shimano Deore M591 10 Speed Shifter Units feature 2-way release for cost effective Dyna-Sys 10-speed shifting performance.


  • Pod design allows the use of these shifters with any brake lever
  • 2-way release allows shifting from various riding positions; the upper lever still performs the same shift function, but it can now swing in either direction allowing it to be released by the thumb or index finger / Low-friction design means that shifters have a light and responsive short-stroke action that reduces shifting effort
  • Dyna-Sys 10-speed compatible - for use with precision 10-speed MTB drivetrains
  • Barrel adjuster for fine gear tuning
  • Easy to read optical gear display / Complete with inner and SP41 outer cables / Easy access clamp band adjustment for quick set up
