The combination of the 10-45 t cassette and 38/28 t crankset offers a massive spectrum of 612%. The new Micro Spline interface with the freewheel body allows 10 t as the smallest sprocket and also prevents the cassette from carving into the freewheel body. The large sprockets are mounted on a carrier, which optimizes weight and power transfer.Shimano XTR M9100 Built on 27 years of MTB innovations, the new XTR targets the highest demanding XC, Enduro and Marathon riders.

Looking to push boundaries, even on those insanely demanding courses nowadays? The new XTR is jam-packed with every advantage you’ll need to get the job done. Heck, it’ll even inspire you to turn yourself inside out while doing it. Shimano's engineers have been working very hard the last 27 years, since they came out with the first ever MTB groupset.

The new XTR is solid proof of this. Redesigned from the bottom up, it is by far the most advanced MTB groupset on the market. It’s lighter, smoother, more durable and versatile.

It’s also extremely efficient in transferring all pedal-pounding watts into ground speed.
