First the rumours, then the presentation, then you find pre-production parts on 2011 bikes. For a real test, however, only Shimano itself makes the really production-ready XTR groupsets available. At the beginning of August 2010 in Lermoos, we were able to ride the cross-country groupset with double and triple cranks and also the XTR for tougher use, known as AM or Trail. This is particularly interesting because it has stronger brakes (Ice Tech), servo wave brake levers, wider pedals and more stable wheels.
In practice, all XTR variants met the high expectations placed on them. The levers feel great in the hand, shifting is as smooth as butter and the brakes are powerful - our disc brake test will soon clarify how good they are compared to the competition. Unfortunately, the new XTR remains a luxury item.

Cassette, cranks and gear ratios
In view of the gear ratio variants, it will be interesting to see which combination the manufacturers choose for different bikes. Before buying, it is worth taking a closer look at the cranks, cassette and crank length to make the right individual choice.
Crank variants
four lengths: 165 mm, 170 mm, 175 mm, 180 mm 170 mm, 172.5 mm, 175 mm, 180 mm (only for 2-fold)
five translations: 42/32/24, 38/26, 40/28, 42/30, 44/30 teeth
Cassette gradations
Gradation 11-36: 11, 13, 15, 17, 19, 21, 24, 28, 32, 36 teeth
Graduation 11-34: 11, 13, 15, 17, 19, 21, 23, 26, 30, 34 teeth
