Details


The concept behind the new DURA-ACE R9100 is based on the principle that each component should be improved to optimise input and maximise output. In other words, to reduce as far as technically possible energy loss between a rider's effort and the actual performance he or she achieves.  That's why each and every DURA-ACE R9100 component has been developed for maximum effectiveness in combination with the rest of the components in the system. This is Shimano's system component concept. The result is a superior system that has truly qualified as having ‘System Supremacy'.

The new DURA-ACE R9100 adopts Synchronized Shifting, a system that Shimano first developed for mountain bikes. This allows riders to operate both derailleurs just by pressing a single shift button. 

The concept of maximising output by minimising energy loss begins with the crankset. The renewed design of the 2x11 HOLLOWTECH II crankset endows the new DURA-ACE groupset with an iconic aesthetic and improves the performance of the gear shift.
