Shimano Launch Dyna-Sys 10 Speed MTB Group
16 Apr, 2010
Component giant Shimano has just announced the launch of a new 10-speed drivetrain technology for mountain bikes called Dyna-Sys. Aside from the extra gear, Dyna-Sys features a completely redesigned drivetrain with many additional benefits. The first Dyna-Sys products for the Deore XT, SLX groups will be available this season.

Closer gear ratios for a smoother shifting performance are the main driver which will improve power transfer creating optimized gear combinations for more efficiency and durability. According to Shimano, Dyna-Sys offers a more stable drivetrain.

Shimano will introduce a wide range of 3 x 10 mountain bike components with the Dyna-Sys drivetrain. The new products launched this year for the Deore XT and SLX groups, as well as Dyna-Sys non-series are an addition to the 9-speed components. They can be recognized by the Dyna-Sys logo. Visually, the components are identical to the 9-speed versions but they include the new component technology.

Dyna-Sys will come in the following mountain bike components. For Deore XT and SLX group sets it includes a Hollowtech II crankset with 42-32-24T, two rear derailleurs, four front derailleurs, shifters, cassette sprockets with 11-36T or 11-34T and a dedicated chain. For the non-series Shimano comes with a Dyna-Sys 2-piece crankset with 42-32-24 teeth.
