The first dedicated MTB groupset just got better!

Shimano DEORE XT is the original mountain bike groupset trusted by generations of mountain bikers around the world. XT’s legendary status is founded on the continual development of new technologies, and it carries on that legacy with the latest group.

Whatever the trail, whatever you ride, XT is your solution for mountain biking today. Reliable shifting. Superior braking. Intuitive maintenance. XT is the high-performance workhorse you can count on.

Building on the experiences of the world’s best mountain bike racers, Shimano has brought its race-winning technology to competitive and enthusiastic mountain bike riders. The new DEORE XT M8100 series, the latest iteration of the original MTB groupset, continues its legacy with high-performance features for today’s demanding and adventurous mountain bikers.

DEORE XT 12-speed cassettes come with the MICRO SPLINE fitting system and in 10-51T for maximum range. This cassette also features HYPERGLIDE+, allowing for quick up and downshifts and an extremely quiet drivetrain. The cassettes have an aluminum spider to house ten steel sprockets and two aluminum sprockets for optimum durability and weight.


The new DEORE XT 12-speed HG chain has been redesigned with an extended inner plate to improve chain engagement and retention and comes with chromized roller link plates for enhanced durability, and smoother and faster shifting both up and down the cassette.


The DEORE XT rear derailleur enables precise and quick shifting over a huge gear range. Both derailleurs feature SHIMANO SHADOW RD+ positioning, bump stoppers and 13T pulley wheels to make rides quieter and more enjoyable.


With side adjustment and rotational adjustment options, the ISPEC-EV shifters, which bolt neatly to the brake lever, offer solutions for tailoring the riding feel. Rubber padding on the paddles and a two-way release enhances shifting even further. The right-hand shifter (SL-M8100-IR) uses a multi-release feature to quickly dump cassette gears.


The DEORE XT brake levers work with both the XC and Trail/Enduro calipers and come equipped with Shimano’s SERVO WAVE system for quicker engagement, improved power, and a shorter free stroke. The brake levers are now angled in two positions against the handlebar for a stiffer brake sensation. The levers also feature a reach adjust dial and a free stroke adjustment screw for simple brake tune-ups on the trail.

These brakes are the 4-piston version – a completely new design drawn from the XTR M9100 design, sharing the same N03A (resin) or N04C (metal) finned pads (compatible also with D03S or D02S pads).


The redesigned DEORE XT-level ICE TECHNOLOGIES FREEZA rotors (RT-MT800) are designed to maximise cooling, resulting in consistent brake performance and longer-lasting brake pads. A sandwiched aluminium core, fused in a durable steel outer layer, dissipates heat via the heat fins in the centre.
