Accurate Readings in all Conditions Shimano have extensively tested this new power meter system to ensure its accuracy and reliability in all weather conditions. The chainset is equipped with dual sided and internally hard-wired crank arm strain gauges, which provide a ±2% power measurement accuracy regardless of your pedalling position. Easy to Maintain The power meter is powered with a simple rechargeable battery for easy maintenance and can be updated wirelessly. As it is mounted to the crank arms 4-arm spider, you can change the chainrings without having to worry about affecting the power measurement. Lighter and stiffer Although the crank arms and spider arms are noticeably bigger to increase stiffness, the overall weight has dropped by 7g over the previous edition of Dura-Ace. The chainset has been adapted to work with disc brake road bikes that generally have 135mm rear hub spacing and shorter chainstays without the need to increase Q-factor thanks to its wider chainring spacing. This Compact version features a 50/34T chainring profile to offer an excellent rider tuned gear combination for varied conditions from flats to high mountains.
With a focus on decreasing disc brake rotor heat deformation, the result of the new Dura-Ace CL900 Ice Tech Freeza Disc Rotor is quieter than ever brake performance without sacrificing weight or heat dissipation.Dura-Ace grade RT-CL900 Ice Tech rotors providing consistent braking performance through energy control, using revolutionary stainless steel / alloy 3-layer sandwich construction that manages heat while ridingThe clad steel / alloy / steel rotor construction allows heat generated from braking to radiate quickly through the aluminium core achieving surface temperature drops of around 50 deg C. When used with Ice Tech pads surface temperatures can drop from around 400 to 300 deg C, this provides great improvements in performance all roundFreeza rotors allow the alloy core to extend out from the braking surface as a fin to providing added coolingIce Tech rotors achieve long pad life, less noise and less fade due to improved heat dispersionRotors are durable lightweight and rigid, using the proven Shimano Centre Lock system giving increased strength and security with an easy set-upPrecision cut braking surface improves pad clearing in muddy conditions while aiding cooling under high loadLarge alloy spider is a highly rigid and lightweight support for the rotor surfaceSuper polished braking surface gives excellent braking performance

4 mm diameter SIS OT-RS900 outer cable casing specifically developed for Dura-Ace R9100 rear derailleur. More pliable than SP41 outer casing, designed to work specifically with the Dura-Ace R9100 Shadow derailleur without B-tension spring. Lubricated internally along its length with low-friction silicon grease to reduce cable friction.Special construction process makes for an axially stiff casing that transmits shifting movements accurately and quickly. Lined with a polymer sheath to assist with the smooth operation of the inner wire.
The Shimano R9100 Dura-Ace 11-Speed Rear Derailleur features a lightweight carbon cage and wide link design for quick accurate shifts and unmatched drivetrain efficiency, full carbon fibre inner and outer pulley plates to enhance rigidity and significantly reduce weight and high tolerance cold forged aluminium link plates and body construction for extremely low weight, strength and durability. Lightweight Carbon Cage and Wide Link Full Carbon Fibre Inner and Outer Pulley Plates Low Profile Shadow Derailleur DesignHard Wearing Dura-Ace Finish and Graphics Weight: 166 GramsThe sealed pulley bearings reduce friction and rotate silky smooth for optimum efficiency, the four self-lubricating micro-machined fluorine-coated link pivot bushings provide low friction shifting and the DuPont Zytel construction of the pulley ensures a longer life and less chain noise. The R9100 is 11-speed compatible, has a 33 tooth total capacity and can operate with wide gear ratios up to a 30-tooth cassette sprocket.
Elite road racers need reliable and precise shifting that is both lightweight and durable, and that s why they choose Shimano s Dura-Ace. The R9100 11-Speed Front Derailleur is part of Shimano s new flagship Dura Ace range, boasting elite level performance in a durable and lightweight package. The Toggle Link Leverage construction reduces weight and improves shifting performance, and thanks to improvements in cage design an outer trim is no longer required, allowing the rider to focus on racing. The lightweight nickel-plated forged alloy chain cage reduces weight and increases rigidity whilst resisting abrasion from the chain and the extra wide pivot link and optimised spring tension creates a rigid, flex free shift whilst remaining a smooth and light action. The forged aluminium construction reduces weight without sacrificing durability, the integrated cable tension adjustment is quick and easy to use and the hard-wearing finish is as good as you would expect from Shimano s flagship range. If you re looking to upgrade you existing Shimano Front Derailleur or replace an entire groupset, the Dura-Ace R9100 will not disappoint.

The uninterrupted shifting experience of the Shimano Dura-Ace R9200 12-speed cassette range lets you climb, sprint and push your limits without stopping to think about your next gear change. Larger driving cogs maximize drivetrain efficiency and create compatibility with both Shimano 11 and 12-speed freehub bodies.Super lightweight 12speed HG+ cassette with a rigid carbon and alloy carrier for excellent shifting even under the most demanding gear changesHyperglide+ sprockets have a computer designed tooth configuration with contoured shift gates, resulting in a crisp smooth shift even under loadClose ratio gearing allows a more efficient use of energy through finer cadence controlLargest sprockets are mounted on lightweight alloy and carbon carriers to reduce weight and increase rigidity5 largest sprockets are made from titanium to reduce weight without sacrificing strengthSprockets are extensively cut away and drilled to further reduce weight without reducing rigidityNickel-plated finish offers hard wearing resistance to corrosionAlloy cassette lock ringFor Super Narrow 12-speed chainsHyperglide+ cassettes have revolutionized off-road shifting with their seamless shifts both up and down the gear range. Now it's time for the technology to change road cycling. Even during maximal efforts up a climb or nearing the finish line, riders no longer need to back off to perform a shift. In any gear, Dura-Ace R9250 drivetrains maximize efficiency thanks to larger cogs and retain compatibility with existing 11-speed freehub bodies. All this while increasing to 12-gears and without increasing weight, Dura-Ace CS-R9200 cassettes are the new paradigm in road shifting.
