The HollowTech II 11-speed Ultegra chainset offers an ideal balance of light weight and stiffness, making it the perfect choice for both enthusiast and competitive riders HollowGlide hollow outer chainring gives vast improvements in rigidity by virtually removing outer chainring flex and hugely improves shift performance, even under high load The chainring teeth have been developed to work in conjunction with 11-speed HG-EV chains for increased contact to provide greater efficiency and improved power transfer Industry leading HollowTech II cold forged 4 arm hollow cranks have been evolved for maximum rigidity while reducing weight Wide gear pitch spacing increases clearance between chain and leading teeth to provide compatibility to frames with O.L.D. 135 / 142 mm and 410mm chain stay length A wide range of chainring options and crank arm lengths are available to meet the needs of all riders and racing disciplines HollowTech II integrated bottom bracket uses a wider bearing placement and larger axle diameter for increased stiffness and efficiency HollowTech II integrated bottom bracket seal design has minimal bearing interface ensuring smooth rolling and increased durability(sold separately)
The Di2 front derailleur's operation is pioneering, smooth shifting is guaranteed thanks to wireless communication with the gear levers. What's more, shifting the rear derailleur automatically trims the front derailleur Full and semi synchronized shifting programable, Synchro shift compatible meaning a single shifter can control both front and rear shifting which can be fully custom tuned to your riding preferences. Semi synchronized shifting means when a front shift is made the rear mech will automatically correct to the appropriate ratio 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 The front derailleur also trims automatically; the cage moves in response to the position of the rear derailleur on the cassette to ensure no chain rub and a quiet unobtrusive ride, enabling you to concentrate on the road ahead Designed to work with the wider gear pitch spacing Shimano chainsets without sacrificing shifting performance on bikes with 135 / 142 mm O.L.D. Braze-on fit as standard; if your bike does not have a braze-on mount seat tube adapters are available 12-speed E-tube SD300 wire compatible

With millimeter accurate shifting guaranteed time after time. Compatible with Shimano's Syncronized Shift technology, this derailleur is intelligently designed, and, with your input, can be programmed to shift in order to maintain optimal gear ratios automatically. Redesigned to fit wider gear pitch, this front derailleur can take chainrings sized up to 53 teeth and go as low as 46 teeth, assuring you of a smooth transmission when switching between the two. Braze-on fit as standard; if your bike does not have a braze-on mount seat tube adapters are available
Shimano Ultegra R8000 175mm 46-36T CX ChainsetShimano Ultegra R8000 has been developed to offer the best balance of stiffness, weight, and rotational performance. This updated design gains all of the performance benefits of its top-tier sibling, Dura-Ace 9000. Ultegra R8000 now features the same lightweight crank arms and hollow outer chainring to reduce weight without sacrificing stiffness. The enhanced rigidity maximises power transfer and ensures optimal pedalling efficiency. A wider gear pitch offers increased clearance on modern road frames that are engineered to be wider and longer at the rear. This 46-36T chainset is tuned for cross, offering enthusiasts and racers alike the optimal gear ratio to overcome the steep climbs and obstacles typical of the toughest cross circuits. The wider gear pitch increases clearance between the chain and leading teeth, ensuring compatibility with frames of O.L.D. 135mm and 410mm chainstay length. A hollow outer chainring greatly improves rigidity by removing flex, resulting in more consistent shifting even under high load.
