Elite road racers demand reliable & precise shifting, & with 10-speed compatibility & super-lightweight yet durable components, the Dura-Ace front derailleur delivers Compatible with Dura-Ace ST7900 shifters & FC-7900 / FC7950 chainsets only for optimum shifting performance Thanks to improvements in the cage design outer trim is no longer required allowing the rider to focus on racing Lightweight nickel-plated forged alloy chain cage reduces weight & increases rigidity whilst resisting abrasion from the chain Extra wide pivot link & optimised spring tension combined with the ST7900 STI lever gives a rigid, flex free shift while being smooth & light action Forged aluminium construction reduces weight without sacrificing durability Hard-wearing Dura-Ace finish Maximum capacity of 16 teeth, for use with outer rings 50-56T Weight: 67 g (braze-on) ...

Shimanos FC-9000 Dura-Ace Chainset is breaking new ground. With its new four arm spider design the chainset is a massive 50g lighter than the previous 5 arm design & is compatible with both compact & double chainrings, no longer do you need a new spider to swap between gear ratios. Despite the new four arm design, the FC-9000 Crankset has lost no stiffness thanks to keeping the solid forged, hollowtech crank design that balances stiffness & weight with all the finesse youd expect from a top of the line chainset. Hollowglide chainrings shave off the weight of the crankset by removing structural material inside of the chainring to reduce the weight of each ring while keeping the same high performance & durability. A new chainguide design helps to reduce chain drop while the teeth on each chainring are optimised for smooth, rapid shift. The unique four arm design & custom BCD allow the new Dura-Ace Chainset to allow chainrings from 50-34T all the way to 55-42T. Key Features Optimum Power Transfer & Lighter Weight Maintains Efficiency New Chain Guide Design to Reduce Chain Drop 4-Arm Construction Crankset Maintains High Rigidity & Reduces Weight Hollowglide Chainrings Maintain Smooth Shifting Whilst Reducing Weight & Increasing Stiffness 110mm Pitch Circle Diameter for Both Compact & Regular Versions Making Gear Ratio Changes Easy ...
