The latest Shimano Ultegra fc 6800 Chainring 11s crankset has an unprecedented price / quality ratio: Dura Ace technology for an Ultegra price with a hollow-forged arm and optimised chainring shape. Thanks to its innovative 4-arm connector every chainring combination will fit on this crank; which means you can ride double and convert to a compact without buying a new crank.

• Innovative HollowTech forged and anodised aluminium crank arms utilise a hollow design that minimises flex and keeps the weight low
• The chainring teeth have been developed to work in conjunction with the CN-5701 chains for increased contact to provide greater efficiency and improved power transfer
• HollowTech II allows the bottom bracket bearings to be spaced wider apart (outboard from the frame), enabling the use of larger bearings and an increased axle diameter
• The system allows for easier installation, adjustment, and maintenance
• Designed to work with HollowTech II type bottom bracket cups (BB not included)
• Lightweight anodised aluminium chainrings for smooth and precise shifting
• Tooth range: 50/34T
