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.
Perfect for pairing up with the rest of the Shimano 105 Di2 groupset, this 12 speed chainset comes kitted out with hollow aluminium crankarms for the best balance of durability, rigidity and low weight. Shimano has also put each crankarm through its anodising process for extra protection against wear and corrosion, making it ideal for enduring mile after mile of road, in all weather conditions. Another highlight is the resin ribs on the back of this model's chainrings, which use Shimano 105's unique structural design to achieve further weight savings and crisp shifting performance. Hollowtech II Technology Providing the best balance of stiffness, strength, weight and rotating performance, the concept of Hollowtech II technology is focused on producing a superior crankset that will maximise your power transfer. The rigidity of the crankset ensures pedalling efficiency while its weight, a key element of the crankset, you want light, aids in cycling longer distances where you need to pedal more. Moreover, the Hollowtech II crankset has a high-precision sealing in the bearing area to increase durability maintaining the excellent rotating performance for long periods. Hollowglide Technology This model features Hollowglide technology on its outer chainring. High rigidity hollow structure cuts down on weight yet maintains strength. Better power transfer and quicker and more precise front shifting. Shimano 105 Di2 brings electronic wireless shifting to a new set of riders. For those who have only experienced mechanical shifting and ergonomics, Shimano 105 Di2 represents a transformation of the road cycling experience. Technologies: - Optimal balance of stiffness, strength, weight and rotational performance. - Hollowglide structure cuts weight yet maintains strength for better power transfer and quicker, more precise front shifting.

This Shimano 105 R7000 11 speed double chainset has been designed and refined to ensure maximum levels of power-transfer from rider to road are maintained. Thanks to modern technology, Shimano has designed this crankset with the perfect gear-pitch so it performs exceptionally with standard road frames (130mm rear dropout spacing) and modern disc brake frames, which have a wider 135mm dropout spacing and wider chainline. This design pushes the advancements of road chainset performance and achieves exceptional levels of efficiency and comfort.
This Shimano bleed kit includes an easy to use syringe and hose to draw the fluid through the caliper, a funnel to accurately fill the lever reservoir and a caliper attachment to keep the hose and syringe in place.
Polymer-coated inner brake cables for the ultimate in smooth braking performance, designed to complement the top-of-the-range Shimano Dura-Ace groupsets. Manufacture Product Code: 63Z 9895
The Shimano SM-CA70 gear cable adjusters are high-grade barrel adjusters which can be installed inline on SP41 outer gear cable to allow fine adjustment of gear indexing.
Can also use 52T Outer Chainring from FC-7900 or FC-5700, these are a "B" match which indicates that the parts are usable, but differ in materials, appearance, finish & size etc.
Fitting new gears or completely overhauling your gear cabling couldn't be easier as the Shimano Optislick gear cables have everything you need in one pack. Optislick is electrically coated to the stainless steel inner wire leaves a smooth surface for low friction and reduced sliding resistance. The outer casing in the Shimano Optislick gear cable set is lubricated internally along its length with low-friction silicone grease to reduce cable friction. The SP41 outer cable uses a special directional wound construction process that makes for an axially stiff cable that transmits shifting movements accurately and quickly. It's also lined with a polymer sheath to assist with the smooth operation of the gear inner cable.
Thie high-grade Shimano SM-CB90 can be installed inline on Shimano Linear Response (SLR) or M-System brake cable to allow fine adjustment of brakes. This makes the Shimano cable tension adjuster the perfect addition to your brake cables so you can change your brake cable tension easily when out on a ride.
Light and durable replacement chainrings.
Shimano's outer gear cable casing is lubricated internally to provide low-friction for smooth shifting on your road or mountain bike. This polymer lined outer gear cable casing is for use with 1.2mm inner cables.
