Specialized S-Works Tarmac SL7 Dura-Ace Di2 Disc Road Bike
With Specialized's S-Works Tarmac SL7 Dura-Ace Di2 Disc Road Bike there are no compromises, it's incredibly fast, uphill and down, bringing together the ride feel and low weight of the Tarmac with the aerodynamic credentials of the Venge. Specialized has managed to make the shape as wind-cheating as possible while reducing weight over the previous generation, thanks to the use of their FreeFoil Shape Library and Win Tunnel testing. It sits around the UCI lower weight limit making it one of the fastest racing machines out there.
The brand's Rider-First Engineered™ philosophy underpins the sublime handling and unmatched ride quality, bringing the same benefits to each and every frame size. Balance is key, and although this bike feels stiff and lively with a Performance Road Geometry, it'll remain comfortable and compliant on the longest rides.
A bike like this deserves only the best components, and Shimano's Dura-Ace Di2 11-speed electronic groupset truly delivers in terms of shifting and braking performance. Mid-compact chainrings are paired with a wide-ranging cassette, and the cranks incorporate a dual-sided power meter for those who are taking their training and racing more seriously. Hydraulic disc brakes will inspire confidence at speed no matter the conditions, and the cables for the entire system are routed internally.
The build is finished with a combination of deep-section Roval Rapide CLX wheels, S-Works Turbo Cotton tyres and the short-nosed S-Works Power saddle that's perfectly suited to aggressive riding positions.
