Details
The concept behind the new Shimano Dura-Ace R9150 groupset was to examine and improve every component to optimise the input and maximise the output. Or to put it another way, to minimise the energy loss between the effort a rider puts in and the performance he or she achieves.
Each component has been re-engineered to ensure maximum stiffness, performance and minimum weight.
