Shimano has been making mountain bike drivetrains for more than three decades, including eight generations of Shimano Deore XT (the original MTB drivetrain) and six generations of its flagship XTR group. Each generation is a reflection of the riding that defined the sport and the technology that defined the era. True to this legacy, our next-generation Dyna-Sys drivetrain brings with it the legendary quality, durability and performance riders expect from Shimano, all packaged to meet the ever-evolving demands of today’s riders.

A wider-range 11-36 10-speed HG cassette means riders can climb further in their Primary Driving Gear—the 32-tooth chainring. When other riders have pulled the rip cord, the Dyna-Sys equipped rider will still be motoring along in a more efficient gear with full traction.

CN-HG94   
Systems engineering is a bedrock principle of Shimano’s holistic design approach, and nowhere is this design harmony more evident than in the first-ever mountain-bike-specific 10-speed chain. With four task-specific plates per link, this new asymmetrical chain was engineered specifically to climb the profile of an HG cassette on one side and catch the pickup pins on Shimano’s already smoothest-in-class front chainrings on the other.

CloseStep front chainring gear ratios —42-32-24— make shifting smoother and faster. With Dyna-Sys, getting from the 24-tooth ring back into the middle ring—the Primary Driving Gear—is easier and more intuitive. Plus, a 42-tooth big-ring is more appropriate for the needs of today’s trail riders.

Thanks to new, more direct Shadow cable routing and the reduced cable tension, Dyna-Sys is less sensitive to contamination, cable stretch and cable routing concerns, which all adds up to more consistent performance in even the roughest terrain—the kind of trails that rattle molars loose and make suspension components work overtime to keep pace.
