Dyna-Sys stands not only for an additional gear, but also for narrower gear steps that shift more smoothly and optimise power transmission. It's about more optimal gear combinations that minimise power loss and wear. Dyna-Sys technology ensures seamless shifting operations. The rider pedals consistently round and efficient. Traction and momentum are always guaranteed.
