Overall DEORE XT T8000 has the durability for daily commuting and the reliability for long touring. Its versatile 3x10-speed drivetrain and precise, stable performance in both off road and on road riding means it can be your trusted group for all your trekking needs.

Shimano raises the bar for dedicated trekking components: The Shimano XT 10-speed rear derailleur RD-T8000 SGS

Meanwhile the 10-speed rear derailleur (36T-11T, 32-11T) now has the option of SHIMANO SHADOW RD technology, which creates a low profile rear derailleur with the function to stabilize the chain and reduce chain noise over rocky terrain, whilst still maintaining easy shifting performance. In addition to that, the new DEORE XT T8000 derailleurs and shifters work with stainless steel cables featuring an OPTISLICK coating for optimum performance.

Dyna-Sys 
SHIMANO presents the drivetrain technology for mountain bikes: DYNA-SYS. This revolutionary technology uses a 10-speed cassette, but that is not the only feature of this system. Highlight is a completely redesigned drivetrain that creates real added benefits for the rider.
