Specialized S-Works Tarmac SL7 RED eTap AXS 12-Speed Disc Road Bike 2021
There's no longer a need to choose between speed, weight and handling, the Specialized S-Works Tarmac SL7 RED eTap AXS 12-Speed Disc Road Bike offers it all. You get the best qualities of both the Tarmac and the Venge; low weight, an incredible ride feel, aerodynamics and sleek integration. The SL7 is constructed from premium FACT 12r Carbon and Specialized utilised their Freefoil Shape Library, testing optimised tube shapes in the Win Tunnel in order to deliver the fastest possible frame. It's also the lightest, and in this build, the bike is kept at or just below the UCI limit.
A Rider-First Engineered™ philosophy is behind the lively ride and handling of the Tarmac SL7 and all of the latest updates were made in collaboration with professional teams. The bike is well-balanced, stiff yet compliant for all-day ride comfort, and every rider will reap the same benefits, no matter the frame size. The proven Performance Road Geometry of the SL6 has been retained, for instantaneous response, optimised power transfer and an aggressive ride position.
Built up with RED eTap AXS 12-speed, SRAM's flagship wireless electronic hydraulic disc groupset, shifting is at its most precise and braking is powerful. Hoses are fully integrated so the cockpit is sleek and fast. The drivetrain offers a wide range of gears, while Orbit Chain Management keeps the changes smooth and quiet. There's even a dual-sided Quarq power meter included for accurate measurement of your power output. Roval Rapide CLX wheels have deep section rims that bring further drag-reducing benefits to the setup but despite their depth, they remain surprisingly stable in crosswinds. There is no more fitting choice of tyres for a wheelset of this calibre than the renowned Specialized S-Works Turbo Cotton clinchers, offering the lowest rolling resistance of any the brand produces. The ride quality is just as good thanks to the supple construction, making this is the ultimate race tyre to match this superbike.
