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.
Die-extruded PTFE coated inner wire leaves a smooth surface for low friction in use, and stainless steel provides smooth shifting and higher corrosion resistance.
Designed specifically with trekking in mind, the Shimano Alivio T4060 9 speed triple chainset is compatible with Hollowtech bottom brackets, which are durable and easy to find replacement parts for when required. Hollowtech bottom brackets come in sizes to fit most frames making this an extremely versatile chainset. Please Note: Bottom bracket is NOT included.
Delivering crisp and precise shifting, even under load, the Shimano Acera HG41 8-Speed cassette has a nickel-plated finish to resist corrosion to add longevity. It offers close ratio sprockets with Shimano's bespoke Hyperglide design.
Fits Centre-Lock Disc rotors and HG cassettes
This stunning model integrates your bottom bracket and chainset into one strong, robust and lightweight workhorse. Furthermore, it is compatible with all new XTR chainrings thanks to its integrated design which makes installation and adjusting easier than ever before. Its precision bottom bracket bearings are spaced further apart and are therefore more stable and longer lasting. What's most impressive, is its super-lightweight HollowTech II cold forged Dualumin crank arms deliver an excellent strength to weight ratio, so you can conquer every technical trail without any unnecessary weight holding you back. If your existing cranks are old or worn-out, this is an ideal choice of a replacement for getting back to fast and precise acceleration and shifting out on the trails. Please note: Bottom Bracket is not included Technologies: HollowTech: Hollow forged crank arms. A lightweight crankset not only reduces the bike’s weight but decreases rotating mass to aid in acceleration. The challenge is to reduce the weight of the crank without reducing its strength and rigidity. Shimano's advanced forging technology has solved the problem through the HollowTech crank. Just like high quality frame tubing, a hollow crank arm can provide amazing strength and rigidity at very lightweight. HollowGlide: Hollow technology on the outer chainring. High rigidity hollow structure cuts down on weight yet maintains strength. Better power transfer and quicker and more precise front shifting.
The XTR M9020 integrates the bottom bracket and crankset into a strong, rigid, yet lightweight unit.
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.
Whether you're fitting new brakes or completely overhauling your brake cabling, this Shimano Dura Ace brake cable set contains everything you need to breathe new life back into your road bike's braking setup. Polymer Coated Stainless Steel Inner Wires Polymer coated stainless steel inner wires leave a smooth surface for low friction and reduced sliding resistance providing a lighter quicker braking operation. Special Spiral Wound Construction for Axial Rigidity The outer casing is lubricated internally along its length with low-friction silicone grease to reduce cable friction and the SLR casing uses a special spiral wound construction that is axially stiff yet can be bent around handlebar curves. The outer casing is also lined with a hard polymer sheath to keep its round shape to assist with the smooth operation of the inner wire. These Shimano Dura Ace brake cables are a great choice of upgrade for replacing your old or worn-out existing cables and enjoying powerful and consistent braking operation on your road bike.
Includes 1.6mm inner wires (1 x 1000mm and 1 x 2050mm), and black 5mm M-System outer casing for a complete bike (1 x 2200mm), and all end caps Sealed end caps with internal O-ring gives an effective seal against the elements, prolonging service life Outer casing is lined with a polymer sheath to assist with the smooth operation of the inner wire
The all-rounder of the new Dura-Ace wheel lineup, the C50 is both lighter than the previous C40 model and nearly as aerodynamic as the previous C60. It's a wheelset at home in a wide range of conditions. From time trials to criteriums, on rolling terrain or attempting a personal best, the new C50 is the ideal wheel for spirited road riding. The perfect blend of low weight and aerodynamic performance, the all-new Dura-Ace C50 features an updated all-carbon tubeless rim and new hub design that drops weight while enhancing rigidity. Centre-Lock Disc Rotor Mount The 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 Profile Aerodynamic 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 System The 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 System The 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.
