Shimano Dura Ace Groupset

The 2016 Shimano Dura Ace Groupset is a top-end road group. Shimano's best mechanical-shift group, Dura Ace is light, durable, and high performance, shifting swiftly along the 11-speed cassette, hopping chainrings smoothly, and offering precise braking control with the calipers. The short-cage rear derailleur can manage up to a 28T; ring options for the light, hollow crankset include everything from a compact 50/34 up to a time trialer's 55T. The rear hub cassette body can accommodate 8-11 speeds.
An excellent road racing group.
