For whatever environments you ride in, Deore XT continues to deliver race-proven, reliable performance. The latest M8100 series derailleurs are lightweight and come with the silkiest up and down shifting... ever.

  • HYPERGLIDE+ drivetrain system enables smooth, quick, quiet and shockless shifting in both directions - no more *thoonk* when dropping the chain to smaller sprockets.
    • Faster shifting -  gear change time reduced by ~33% vs. HG drivetrains.
    • Less shifting shock means smoother, more efficient pedaling when it's needed most.
  • 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.
  • Single screw clutch tension adjuster makes fine tuning quick and easy.
    • 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.

    Our thoughts:
    XT has long been a favourite choice among serious MTB riders. The M8100 derailleurs don't aim to change that, delivering all of Shimano's current features in the product category. 

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