Introducing the Shimano Ultegra R8020 Disc Brake Groupset – 52/36 11/28. This is the perfect set up for enthusiast and competitive riders, vast improvements in rigidity hugely improves your performance, even under a high load. Your bike will be able to accurately shift between gears with excellent drive chain efficiency. Suitable for disc brakes, you’ll find it easy to control and power you bike with minimal effort in all riding conditions.Groupset:Gear Shifters – Precision-engineered Ultegra STI levers with hydraulic disc brakes give you control, modulation and power with minimal effort in all riding conditions. Shift cables are routed under the bar tape: re-development and positioning of the internal mechanism in combination with Polymer coated cables have made this possible, providing faster, lighter and smoother shifting. Featuring an ergonomic shift arc which follows natural hand movement with inward shift stroke distance reduced for rapid and precise gear changes and hydraulic reservoir tank provides pad to rotor clearance auto-adjust maintaining braking performance during pad wear.Derailleur’s – At the front is the R8000 Ultegra 11-speed front derailleur, double braze-on with a toggle link construction, which matches the force curve of the hand more naturally. With a short lever movement and less effort at the end of the shifting stroke. Wide inner link increased rigidity and takes front shifting performance to a new level, especially under heavy load. At the rear is the R8000 Ultegra 11-speed rear derailleur with shadow, wide link design, giving quick accurate drive train efficiency. Chainset – R8000 Ultegra 11-speed double chainset, 52 / 36T. The 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. Featuring industry leading HollowTech II cold forged 4 arm hollow cranks have been evolved for maximum rigidity while reducing weight.Cassette – The CS-R8000 Ultegra 11-speed cassette 11 – 28T is a lightweight rigid alloy cassette, ideal to meet the needs of any rider. Hyperglide EV sprockets have been designed to reduce weight with improve teeth shaping providing accurate shifting and reduced wear.
