прим.:перенесено из новостей от 29.06.2010 | Встречаем объект любви многих веломаньяков- обновленная группа Shimano XTR - 2011! |
Начнем с систем.
Как и ожидалось, в след за СРАМом и другими, XTR переходит на 2*10.
Будет доступен и двойник и тройник спереди, причем звезды на к шатунам крепятся как-то по хитрому, есть мнение что для этих систем подойдут только "свои" звезды. Средняя звезда тройника карбон+титан будет очень дорогой в случае замены. Двойные системы будут доступны в трех вариантах в соответствии с условиями и силой ног: 40T-28T, 42T-30T, and 44T-30T. А вообще, системы красивы:
38T-24T
42T-32T-24T
На системах красуется лейбл Dyna-Sys.
Главным отличием является использование 10-скоростной кассеты (заднего блока звезд), а также переднего блоки и цепи, оптимизированной для работы в таком комплекте.
Dyna-sys дает следующие преимущества:
- меньший шаг между передачами, что позволяет переключать передачи более плавно
- оптимизированные для велосипедиста соотношения передач, повышающее эффективность их использования
- в результате получается более стабильная система переключения передач для любого из стилей езды.

Манетки поменяли дизайн:
SL-M980 RapidFire Plus Shift Lever for double and tripleFront shifter features mode converter for use on either double or triple front chainwheel (shown at bottom of post in the “on the bike” photos)
VIVID index creates tactile rider feedback while maintaining low, linear shifting effort across the entire cog range
Instant release for quick accurate shifting and multi-release for shifting several gears at a time
2-way release trigger allows thumb or finger actuation
I-Spec clamp options for lightest weight when combine with XTR brake levers (shown below)
Multi-bearing construction for greater durability and reduced effort
Estimated weight: 195g/pr (I-Spec), 207g/pr (traditional clamp)

Педали - просто произведение искусства, две версии - традиционная и с платформой, типа для Trail'а. Обычные педали стали легче на 15гр., при этом увеличилась площадь контактирующая с обувью для лучшей стабильности.
PD-M980 – SPD Clipless Pedal
The body has improved mud shedding capabilities due to an oval shaped axle body housing, a more slim profile to the axle body, and offset bindings to allow debris to better flow through the pedal
Power transfer efficiency is improved by increasing shoe and pedal body contact by 270% over PD-M970.
Wider bearing placement also provide great pedaling stability and bearing durability
The new axle body is also lighter, reducing weight by 15g vs. PD-M970
Continues to offer trademark SPD clipless pedal performance
Estimated weight: 310g/pr
PD-M985 – SPD / Platform Trail PedalA new platform designed specifically for trail use
158% more shoe/pedal contact vs. M980 with a 5.8mm wider platform
Wider bearing placement provides great pedaling stability
Integrated pedal cage allows for continuous pedaling even when not clipped in and better pedaling stability when cleats are engaged
The cage also provides binding protection from rocks on rough trails
Oval shaped axle body housing allows mud to more easily flow through
Estimated weight: 398g
