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.
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.
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.
Light and durable replacement chainrings.
