Shimano XT M780 10 Speed Triple Groupset

SHIMANO DEORE XT, the world’s first mountain biking component group is completely revamped for its 30th birthday.

From the early days until today, “XT” has been the benchmark in mountain bike component technology, excelling in quality, innovation and performance combined with an extensive product range to suit a wide range of riding styles. The new group fits well in this tradition, once again boosting the value and relevance of the components.


  • 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!


The ever popular and more versatile triple comes with a 42-32-24T chainring 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:

The new XT SERVO-WAVE disc brakes with Ice-Tec technology provide huge leaps in braking, control and heat management. The new compact caliper with oversized 22mm ceramic pistons is combined with a lightweight lever for a brake that is lighter than the current version, yet provides more brake power.
