Shifting Your Expectations
The DURA-ACE series is SHIMANO's lightest, most ergonomic, and most precise groupset ever. As well as delivering the finest mechanical performance, it also serves as the core chassis for our revolutionary Di2 digital shifting system. The extra eleventh gear and numerous other enhancements combine to deliver a truly dominating performance. When you ride DURA-ACE, you're riding to win.
Don't settle for 'almost perfect'. Use our Groupset Builder to create your preferred mix of ratios and sizes.
A 2 year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).
