Shimano responds to SRAM with Dyna-sys drivetrain system with triple and double ring options

XTR 2011 goes ten speed

As predicted, Shimano XTR has gone ten-speed with two variations of the groupset suited to both cross-country and all mountain riding.

The new group is designed around the Dyna-Sys drivetrain system and will be available in triple and double crankset options.

The manufacturer has also introduced a new cooling technology for its disc brakes dubbed 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 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 ten grams. Horizontal micro-adjustment is possible for a customized set-up.

Following the ‘rider tuned’ concept, XTR will include two types of SPD pedals. One model has been developed for cross country use 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.
