t’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!
The ever popular and more versatile triple comes with a 42-32-24T chain ring combination with the proven composite enhanced middle ring for maximum shift smoothness and durability. Most notably, the 24T inner ring offers a significant improvement in efficiency compared with a 22T and still provides a very low gear for climbing when paired with a 36T rear sprocket.
Ice Technologies disc brakes
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.
Matching Ice-Tec SM-RT98 Centerlock and SM-RT86 6-bolt rotors in 160mm, 180mm and 203mm are available separately.
