The new SLX M7100 Series groupset delivers impressive value and great looks while promising dependability and an enhanced riding experience for a wide variety of MTB applications. SLX derailleurs come in two flavours, each to be paired with its corresponding front crank (1x or 2x).

  • HYPERGLIDE+ drivetrain system enables smooth, quick, quiet and shockless shifting in both directions - no more *thoonk* when dropping the chain to smaller sprockets.
  • SHIMANO SHADOW RD+ chain stabilizing system (clutch):
    • keeps chain taut, reducing both noise and damage to chainstay
    • is lighter and more efficient than roller chain-guide systems 
    • toggles on and off for easier maintenance.
  • Reduced chain tension in low gear chain position (on large sprocket) ensures a silent drivetrain in all gears.
  • Hidden away, low-profile design helps avoid derailleur damage.
  • Features a larger, 13T pulley with a new bumper to help further dampen any chain sound.
  • Bumper structure at rear derailleur pulley cage reduces impact shock by absorbing chain impact on aggressive terrain.


    1x12s (10T-51T)

    2x12s (10T-45T)
    Max. front difference: 10T
    Total capacity: 45T

    Our thoughts:
    SLX M7100 Series components are a great choice and these rear derailleurs are no exception. Shimano has been generous with the amount of innovations they've passed down from the higher tiers, making the SLX a smart choice, as long as you like the colour.

    Keep in mind
    Compatible cassettes employ a MICRO SPLINE rear hub mount (freehub body).
