Trek Project One Emonda SLR 9 Di2 Disc Road Bike 2021
Billed by Trek as the fastest climbing bike that they have ever made, introducing the Project One Emonda SLR 9 Di2 Disc Road Bike. Despite the frame weighing less than 700 grams (claimed), the Ultralight 800 Series OCLV Carbon frame and fork also have aerodynamic qualities so that it can be quick on the way to the climbs as well as when the road heads uphill. Ride Tuned performance tube optimisation blends comfort and stiffness for maximum efficiency, as is to be expected from a bike used by the highly successful Trek-Segafredo pro team. Lightweight, tubeless-ready Bontrager Aeolus RSL 37 OCLV carbon wheels also help on the speed front, with their low weight and wind-cheating design making them equally adept on all parcours.
Shimano’s Dura-Ace Di2 electronic 11-speed groupset is the brand’s premier offering, giving lightning-fast and precise shifting at the touch of a button and components that have been designed with an eye on both weight and performance. The Dura-Ace hydraulic disc brakes are equally impressive, providing fade-free power and easy modulation to help control speed whether on short, sharp descents or sweeping alpine passes, and all with just a light squeeze of the lever.
