DYNA-SYS
Next Generation...

Shimano present a completely new drivetrain technology for mountain bikes: Dyna-Sys.

This revolutionary technology uses a 10-speed cassette, but that is not the only feature of this new system.

It is a completely redesigned drivetrain that creates real added benefits for the rider, it 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!
