Shimano release new Dura-Ace R9100 and R9150 Di2 groupsets

It’s (nearly) here! Shimano have released news of their latest and most advanced groupsets ever, the Dura-Ace R9100 mechanical and R9150 electric.


There are several firsts for Shimano here, including the option to add in an integrated crank-based power meter and/or hydraulic disc-braking. The all new synchronised shifting technology, which seeks the next highest/lowest gear from the touch of one button on the right lever without having to change ring, could be of particular benefit to triathletes on race-day looking for even quicker and smoother shifting. Perhaps lesser news for triathletes but more important for roadies is that the groupset can be purchased with hydraulic disc brakes. The new Dura-Ace rotor is said to improve heat dissipation, and features flat-mount calipers.
