Shimano Ultegra R8000 172.5mm 11 Speed Chainset 46/36

Eagerly anticipated, the updated Shimano Ultegra R8000 Double 11-Speed Chainset has arrived. Featuring clear improvements on aesthetics and performance from the 6800 series, the Ultegra R8000 series has hugely benefited from the trickle-down technology of its big brother, Dura Ace R9000. Offering weight reduction without sacrificing stiffness. It enables a wide range of gear combinations to suit your every need. Paired with the new front and rear derailleurs, your shifts will be so fast and reliable you’ll almost question whether they happened at all! The beautifully shaped crankarm, trickled down from Dura-Ace, is a tribute to the aesthetics of your bike.
