Shimano Dura-Ace 9000 Road Gear Cable Set Gear Cables
  • £25.99
  • RRP £47.99
  • Saving you £46

Fitting new gears or completely overhauling your gear cabling couldn't be easier, as this Shimano Dura-Ace gear cable kit comes with everything you need in one pack. It includes 1.2mm polymer coated inner wires (1x 2100mm, 1x 1800mm), SP41 outer casing for a complete bike (1x 1700mm) and all the required cable end caps. The polymer coated stainless steel inner cable on this Shimano Dura-Ace gear cable set leaves a smooth surface for low friction and reduced sliding resistance providing a lighter quicker shifting operation. The outer casing is lubricated internally along its length with low-friction silicone grease to reduce cable friction. Also, SP 41 outer casing uses a special directional wound construction process that makes for an axially stiff cable that transmits shifting movements accurately and quickly. Plus, this outer casing is lined with a polymer sheath to assist with the smooth operation of the inner cable.

Shimano Dura-Ace DI2 Cable Set Gear Cable Spares

To ensure that the signal goes from the shifter to the derailleurs, the reliability of the electric cable has been proven by repeated field tests in various riding conditions, including extreme temperatures, rain,mud, and cobble stone roads. The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shifts. Dura-Ace Di2 requires 2 cables: a handlebar cable set to connect the shifters to a battery indicator junction box or FlightDeck, and the other to connect the handlebar cable to the battery and derailleurs.

Shimano ST-R9160 Dura-Ace Di2 STI 2x11 Speed Gear Levers
  • £349.99

The electronic shifters enable changing between gears at the click of a button when in the aero position. Having the integrated brake levers in the same position at the front of the TT bars provides the rider with total racing confidence and supreme performance Pure Performance The levers are made from carbon and aluminium so they are much lighter than traditional STI levers and have been designed to enhance performance. The weight is reduced and performance increased even further due to there being no mechanical cables to control the gearing. As these levers use Di2 technology, they function by using lightweight electrical cables to effortlessly command your derailleurs to shift up and down gears. Enhanced Rider Customisation The positioning of the shift buttons and the ergonomics of the brake lever blades allows you to both brake and shift at the same time. This means you can brake late into tight corners, change gear instantly and accelerate back to your regular speed without needing to change your aerodynamic saddle positioning. The brake levers also have tuneable reach adjusters to enhance rider customisation, so you can truly feel at one with your bike.

Shimano Dura-Ace R9270 C36 Carbon CL Disc Wheel - Black - Rear}, Black
  • £699.99
  • RRP £859.99
  • Saving you £19

Shimano Dura-Ace R9270 C36 Carbon CL Disc WheelThe Dura-Ace R9270 C36 Carbon CL Disc Wheel from Shimano is a Tubeless Ready mid-depth-profile wheel that's versatile for steep climbs, fast sprints and long days in the saddle. It features a 36mm-profile full-carbon rim and a Centre Lock disc rotor mount while being compatible with 12mm E-Thru axles, this race-ready wheel is fast, aerodynamic and stable for road racing anywhere.With stunning acceleration, the new Dura-Ace R9270 C36 wheelset will change the way you experience climbs, corners, even stoplights. This is because it isn't just how much a wheel weighs but where the weight is on the wheel that matters. The all-new C36 design shaves mass at every opportunity but especially at the rim. The result is a lively wheelset that can transform your ride. Lighter, Wider and Faster Carbon Road Race WheelWith both a lighter, wider all-carbon rim and a lighter hub, the new Dura-Ace C36 won't shy away from a day of climbing. The new rim is 36 mm deep and still delivers good aerodynamic efficiency despite its gossamer weight. Meanwhile, the hub features an alloy freehub body and a new engagement mechanism for increased rigidity. Centre-Lock Disc Rotor MountThe Centre Lock system makes an easy rotor installation possible with a spline mount and a lock ring. The lock ring mounting system reduces the total working hours by shortening the amount of time of both installation and de-installation. In addition, the secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency. D2 Aerodynamic Rim ProfileAerodynamic performance is affected by wind direction. To create the D2 rim, Shimano engineers considered both frontal and crosswinds, aiming to achieve optimal performance in real-world riding conditions. Extensive prototype testing, in the wind tunnel and on the road, proved that a wide rim shape with a deep tire bed performs best across a wide range of conditions. At yaw angles ranging from 0 to 15 degrees, the Shimano D2 rim profile reduces air drag better than others aero shape rims. This rim design also boosts lateral wheel stiffness and offers improved vertical compliance for increased control, comfort and durability on the road. Rear Wheel OPTBAL Spoke SystemThe OPTBAL rear wheel spoke system features 21 spokes—14 on the drive side and 7 on the non-drive side. Cassette spacing in today's wheels produces unbalanced tension in traditional 1:1 spoke systems. This unbalance is intensified with the 11-speed cassette, producing nearly double the tension on the drive side spokes. Generally, high and low tension spokes have respectively tendency toward breaking down and coming loose spoke nipples. Unbalanced tension affects durability and strength. The OPTBAL design rebalances spoke tension, enhancing wheel rigidity and strength for a more durable wheel. Shimano E-Thru Axle SystemThe tool-less type thru-axle skewer system optimizes rigidity and weight balance and enables easy operation with a reliable internal cam mechanism. The 15 mm thru-axle system is 15% stiffer torsionally and 25% stiffer in transverse shear than a traditional 9 mm quick release front axle system. High rigidity is secured while keeping the optimum weight balance. The E-Thru axle hub system minimizes the distortion of suspension while maintaining lightweight for riding around sharp corners at high speed. Features: Series: Dura-Ace R9200 Series 36 mm height Full Carbon Internal rim width: 21mm Disc Brake Mount: Centre Lock Disc D2 Aerodynamic rim profile Axle System: 12 mm E-Thru / Hub Spacing (O.L.D.): Front: 100mm; Rear: 142mm Freehub: Shimano 12-Speed (Compatible only with Shimano road 12-Speed cassette sprockets) Tyre Type: Clincher Tubeless Recommended Tyre Size: 25-622 - 32-622 Weight: 730g (rear); 620g (front)A 2-year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).Buy Shimano Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

This wheel is fast, agile and stable, and it's optimised with Shimano D2 Aerodynamic Rim Profiling - it's the ideal wheel design for time trial, triathlon and criterium events. And the rear wheel is compatible with Shimano HG 11 and 12-Speed cassettes.Perfect for flatter courses and time trials, the Dura-Ace C60 prioritizes aerodynamic efficiency and lateral rigidity. The new hub design, stiffer spokes, and deep-section rim are designed specifically to allow you to push harder in corners and ensure that every bit of your effort is translated into forward motion. Like the entire Dura-Ace wheel family, the new C60 started with a blank slate. Different from the C36 and C50, the C60 has a specific front hub design using Shimano's OPTBAL 2:1 spoke pattern to enhance lateral rigidity. The C60 also receives stiffer spokes, 1.8 mm instead of 1.5 mm. Tested by our professional athletes, this focus on the lateral rigidity of C60 allows you to push harder in corners and when manoeuvring at higher speeds. Lastly, the new wind-tunnel tested, deep-section rims feature a faster, more stable cross-section that time trialists, triathletes, and sprinters alike will enjoy.
