Ganze 18 Jahre sind seit der ersten Shimano XTR-Gruppe M900 vergangen und lange wurde auf die neue Auflage der XTR gewartet. Nach etlichen Spekulationen im Vorfeld und der Präsentation der XT und SLX Gruppen im Frühjahr ist es nun soweit: Shimano präsentiert sein neues Flagschiff der Öffentlichkeit – und wie erwartet mit einem zehnten Ritzel am Heck. Fokus Leichtbau: In Sachen Gewicht hat sich einiges getan. Weit über 200 Gramm wurde die M980er Gruppe in der leichtesten Konfiguration gegenüber dem Vorgänger M970 abgespeckt und vielen Ecken optisch aufgehübscht. Neu im Programm ist nun auch eine eigenständige 2fach Kurbelgarnitur – Shimanos erwartete Reaktion auf SRAMs 2×10 Politik.
Nicht nur an die XC-Racer unter den Mountainbike-Freaks wurde gedacht. Shimano möchte künftig mit der XTR ebenso verstärkt auf das All-Mountain Pferd setzen und bietet deshalb eine Modellerweiterung um Steckachssysteme, AM-Laufräder, angepasste Scheibenbremshebel BL-M988 und Plattformpedalen an.
Wie auch schon zur Veröffentlichung der aktuellen Dura Ace gibt es für die neue XTR eine eigene Webseite: ride XTR

New SHIMANO XTR developed for XC and AM category
Rider Tuned concept widens XTR user profile
NUNSPEET (The Netherlands) June 28, 2010 – In the development phase of the new XTR group, Shimano engineers and designers focused on a rider-tuned concept which means that the components have been engineered to perfectly match the needs and riding styles of individual mountain bikers. This broadens the scope of XTR and makes it the benchmark not only for Cross Country (XC) racers but for All Mountain (AM) riders too.
The new SHIMANO XTR offers a wide range of products in an attractive design that will raise the bar in mountain bike components and appeal to a wide variety of riders.
The XTR components for XC will set a new benchmark in terms of a super lightweight design while offering a further improved smooth and effortless handling. The dedicated All Mountain components have been developed with a hard core usage in mind, focusing on rigidity and extra brake power for example.
Highlight of the new group is the 10-speed Dyna-Sys drivetrain system with triple and double crankset options. Finally an efficient and functional 3 X 10 drivetrain will be available that will for sure be popular amongst a wide range of mountain bikers. Dyna-Sys, introduced earlier this year at DEORE XT and SLX level, creates real added benefits to the rider:
Dyna-Sys
Ø It’s not only an extra gear…
Ø It’s about closer gear ratios for a smoother shifting performance and improved power transfer
Ø It’s about riding optimized gear combinations that improve efficiency and durability
Ø It’s all about performance: Dyna-Sys offers a more stable drivetrain for any type of rider!
Ice-Tec
Shimano is introducing a completely new cooling technology for disc brakes named “Ice-Tecâ€. Ice-Tec brake pads and rotors significantly reduce heat build-up in the disc brake system. This in turn reduces fading, which assures consistently high braking performance even on long downhill stretches. It also results in longer pad life and substantially quieter braking.
Ice-Tec brake pads have been provided with an aluminum radiator fin with a stainless steel two layer back plate structure. Ice-Tec rotors have an aluminum core sandwiched in stainless steel for improved heat dissipation.
I-Spec
The new XTR offers an integrated mount system for the brake lever and shift lever, named “I-Specâ€. With I-Spec, only one clamp band is needed which looks good and saves space on the handlebar besides saving around 10g. Horizontal micro-adjustment is possible for a customized set-up.
Pedals and wheels
Following the “Rider Tuned†concept, XTR will include two types of SPD pedals. One model has been developed for Cross Country usage focusing on a super lightweight design. The other model is targeted to All Mountain riders, with a wider platform for an improved grip. Also many wheel choices will be available for any kind of riding style from XC Racing to All Mountain.
