The Shimano Dura Ace R9120 11 Speed Groupset includes:

Shimano Dura Ace FC-9100 Chainset

The HollowTech II 11-speed Dura-Ace chainset offers the optimum balance of light weight and rigidity, making it the global choice for road racing's elite riders.

• Hollow outer chainring, giving vast improvements in rigidity and increased weight savings
• The hollow outer chainring has essentially removed outer chainring flex, hugely improving shift performance making it precise even under high load
• These industry leading HollowTech II 4 arm cold forged hollow crank arms have been evolved to increase rigidity, reduce weight, and improve strength
• The teeth have been developed to work only in conjunction with the 11-speed chains for improved contact providing more efficiency and improved power transfer
• There is a wide range of chainring ratios and crank arm lengths available enabling customisation for all riders and racing disciplines
• HollowTech II integrated bottom bracket design uses a wider bearing placement and larger axle diameter for increased stiffness and efficiency
• Bottom bracket seal design has a minimal bearing interface gives superbly smooth rolling and increased durability
• Weight: 609 grams (50-34T)

Shimano Dura Ace CS-R9100 Cassette - 11 Speed

Super lightweight 11-speed HG-EV cassette with a rigid carbon and alloy carrier for excellent shifting even under the most demanding gear changes.

• Hyperglide EV sprockets have a computer designed tooth configuration with contoured shift gates, resulting in a crisp smooth shift even under load
• Close ratio gearing allows a more efficient use of energy through finer cadence control
• Largest sprockets are mounted on lightweight alloy and carbon carriers to reduce weight and increase rigidity
• 5 largest sprockets are made from titanium to reduce weight without sacrificing strength
• Sprockets are extensively cut away and drilled to further reduce weight without reducing rigidity
• Nickel-plated finish offers hard wearing resistance to corrosion
• Alloy cassette lockring
• For Super Narrow 11-speed HG-EV chains
• Average weight 175 grams for 11-25 tooth

Shimano Dura Ace FD-R9100 Front Derailleur

Elite road racers demand reliable and precise shifting, 11-speed Dura-Ace R9100 delivers with its super-lightweight yet durable design.

• Lighter and intuitive shifting operation thanks to toggle link leverage construction
• 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 and increases rigidity whilst resisting abrasion from the chain
• Extra wide pivot link and optimised spring tension gives a rigid, flex free shift while being smooth and light action
• Forged aluminium construction reduces weight without sacrificing durability
• Hard-wearing finish expected of Dura-Ace
• Integrated cable tension adjustment
• Maximum capacity of 16 teeth, for use with outer rings 50-55T
• Weight: 69 g (braze-on)

Shimano Dura Ace RD-R9100 Rear Derailleur - Short Cage

Dura-Ace rear derailleur with lightweight carbon cage and wide link design gives quick accurate shifts, and unmatched drivetrain efficiency.

• Low profile Shadow derailleur design
• High tolerance cold forged aluminium link plates and body construction provide for extremely light weight, strength and durability
• High rigidity wide outer link plates the pulley body to increase pivot joint rigidity
• Sealed pulley bearings reduce friction and rotate silky smooth increasing efficiently
• Four self-lubricating micro-machined fluorine-coated link pivot bushings provide low-friction shifting
• Pulleys are made of tough DuPont Zytel for longer life and less chain noise
• With a total capacity of 33 tooth, it is able to operate with wide gear ratios up to a 30 tooth cassette sprocket
• Hard wearing Dura-Ace finish and graphics for long lasting good looks
• 11-speed compatible
• Weight: 166 grams

Shimano Dura Ace R9120-DL Mechanical STI Set – Flat mount caliper set

• Precision-engineered high performance Dura-Ace hydraulic disc brake STI's give you control, modulation and power with minimal effort in all riding conditions
• Dura-Ace R9100 STI are lightweight thanks to carbon fibre lever blades, carbon composite bracket body, and a titanium clamp band / fixing bolt
• Hydraulic brake lever provides excellent stopping power with less effort especially from the hood position
• Hydraulic reservoir tank provides pad to rotor clearance auto-adjust maintaining braking performance during pad wear
• Shift cables routed under the bar tape using Polymer coated inner wires make for a smooth shift action, providing faster, lighter shifting
• Vivid Index shifting with short stroke to the release levers gives a quick and accurate shift
• Gear shift cables can either be routed round the front or rear of the handlebar to suit all rider preferences
• Ergonomic shift arc follows natural hand movement with inward shift stroke distance reduced for rapid and precise gear changes
• Small volume ergonomically designed smooth lever hoods for added comfort
• Finely tuneable reach adjusters for the levers enable custom fitment for all hands
• Free stroke adjustment for pad to rotor contact setting
