Shimano Dura-Ace 7800 Double Crankset:
This is the new version of Shimano’s dura-ace race crankset. The dura-ace crankset is available in both standard and compact versions, along with a range of crank lengths. To suit your individual requirement.
The crankset has been aerodynamically designed alongside some new engineering features, which Shimano claim give remarkable weight savings. It’s a forged design made from aluminum, which, designed with the thin crank wall and hollow chain rings keeps the weight to an absolute minimum.
To make your ride quieter Shimano has redesigned the tooth profile to make shifting quiet, easy, and trouble free.
