Specialized S-Works Tarmac SL7 Dura Ace Di2 Road Bike 2022
The Specialized S-Works Tarmac SL7 Dura Ace Di2 Road Bike seamlessly merges aerodynamics, low weight and a stunning ride quality to produce a quick, comfortable and efficient ride across any route, whether mountainous, flat or punchy like an Ardennes classic. The frame uses the finest grade of carbon within its construction to bring its weight down to just 800 grams (painted, size 56) while maintaining exceptional lateral stiffness, promoting nimble climbing and snappy acceleration. This carbon material is formed into tube profiles conceived in Specialized’s own “Win Tunnel”, and these combine with the aerodynamic handlebar and hidden brake hoses to elicit incredibly low drag across a complete sweep of yaw angles.
The Rider First Engineered concept is applied to the frameset, balancing its stiffness and vertical compliance across the front and rear of its design, and along with clearance for plush 32mm tyres, this ensures comfort, poise and stability, regardless of the frame size.
A race-inspired frameset geometry places the rider powerfully over the pedals, allowing them to transfer all their energy to the lightweight, aerodynamic Roval CLX wheelset. This wheelset is driven by the Shimano Dura-Ace R9200 12-speed gears that use their semi-wireless electronic format to action lightning fast, smooth and reliable gear changes. In addition, this drivetrain setup includes a power meter within the crank arms to help the rider accurately track their training and racing performances. Stopping duties are charged to the hydraulic disc brakes, and these perform flawlessly, affording confidence on even the most rain-soaked mountain descents.
