Dyna-Sys combines features like quick-shifting CloseStep front gear ratios (think: bigger granny, smaller big ring), a wide-range 11- to 36-tooth 10-speed cassette and re-engineered shifters and derailleurs that are less susceptible to trail chatter or contamination. Together, Shimano Systems Engineering unlocks performance and versatility never before seen in a triple, and it's all tied together with the industry's first mountain-bike-specific 10-speed chain.
Riders who would otherwise have to pull the ripcord and battle technical climbs from the trenches of their granny gear range can now push further up the trail in their middle ring thanks to the increased range of a 36-tooth low-end rear gear. The granny gear is still there, you'll just need it less, and the 42-tooth big ring is more useable and easier to get into than ever before, so you'll use it more.
