Shimano XTR 2011

New SHIMANO XTR developed for XC and AM category
Rider Tuned concept widens XTR user profile

Peterborough (Ontario, CAN) 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. 

  XTR has become two distinct groups.  Here you see the XC version – interestingly with a conventional QR front hub.

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. 

    The AM version adds a 15mm front hub – but the 20mm XTR front has been eliminated.

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: 

  XTR cranks have always been a thing to behold – and the trend continues.

Dyna-Sys
It’s not only an extra gear…
It’s about closer gear ratios for a smoother shifting performance and improved power transfer
It’s about riding optimized gear combinations that improve efficiency and durability
It’s all about performance: Dyna-Sys offers a more stable drivetrain for any type of rider! 

  This is a shifter.

Ice-Tec
Shimano is introducing a completely new cooling technology for disc brakes named “Ice-Tec”. 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. 

   The new changers retain the Shadow factor but have changed significantly.

I-Spec
The new XTR offers an integrated mount system for the brake lever and shift lever, named “I-Spec”. 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. 

  I-Spec is a similar idea to SRAM’s Matchmaker.  One clamp holds both the brake and the shifter.  Something Shimano has done before as well.  Here we see the AM brake lever.

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.

  The XC wheelset weighs in at 1480 grams while the AM sets are 1650 and 1700.
