Welcome to the wonderfully simple world of 1x11 drivetrains. The Shimano Deore XT M8000 single groupset brings simplicity to your mountain bike. An 1x11 drivetrain won't give you trouble like chainsuck or a rattling front derailleur. Removing any excess parts of the drivetrain will also reduce the overall weight of your bike slightly.

Ever since its inception, Shimano XT is synonymous with high quality at a relatively low price. The XT M8000 has been fully redesigned. Not only does the XT M8000 feature the latest 11-speed technologies, the looks of the XT M8000 have also been given an update over the previous XT M785.

The 1x11 design combines wide steel teeth with specially shaped teeth designed to prevent the chain from getting dropped from the ring, not even on the toughest terrains. These improvements have boosted drive train efficiency by 150%, meaning the chain will last for longer and dropped chains on shifts have become a thing of the past.

Detailed product description

• I Spec II
The XT M8000 groupset is, like the previous XTR groupset before it, fitted with the I-Spec II brake and shifter mounting system. I-Spec ensures your shifters are neatly integrated into the collar clamps used by your brakes. The mount isn’t compatible with the older I-Spec A/B type.

• Rhythm Step
Rhythm Step does what it says on the box really. Few things can be as annoying as coming out of your rhythm during your mountain bike ride. The special Rhythm Step cassette has a clever build-up of cogs with smaller jumps between gears. This clever design will save you both a lot of energy and irritation, allowing you to stay focused on the trails and climbs to come.

• Rider Tuned 11 speed
No two rides are alike, something they know all too well at Shimano. The cranks for the XT M8000 groupset is suitable for both single and double chain rings. Combine them with an 11-40 or 11-42 cassette, and you really can tackle any terrain.
