One-Piece Bottom Bracket/Chainstay

The BB (Bottom Bracket) and chainstays are moulded together creating a single unit rather than bonded together after moulding. This results in a super-strong and stiff seamless unit from the BB to the dropouts. This one-piece design resists deflection under extreme pedal loads for improved power transfer.

Here's What Specialized said about their S-Works Tarmac SL6 Di2

  • The previous Tarmac had an exceptional palmarès—a win in every Grand Tour, plus two World Championships—so you might ask yourself, "why a new Tarmac?" Well, we've never been one to rest on our laurels, which is why we're constantly hunting for even the smallest of improvements. In other words, we innovate or die. And for this exact reason, the new S-Works Tarmac breaks all the traditions of race bike design to create the fastest bike for all conditions.

  • We also took major steps to improving our Rider-First Engineered™ technology to ensure that the new Tarmac is stiff and compliant in exactly the right places, all while shedding some serious weight. From different layup schedules and materials, to visibly different forks, we scrutinized every single aspect of the new Tarmac to ensure you're getting the perfect ride. With this revamp, we also updated the geometry, basing it on countless Retül data points and professional rider input. This enabled us to develop a Performance Road Geometry that perfects the combination of a responsive front-end and short wheelbase, which delivers instantaneous response and optimal power transfer.

  • This S-Works Tarmac comes ready to race with Shimano's new Dura-Ace 9150 Di2 groupset with direct mount brakes and the lightweight, yet impressively aerodynamic, Roval CLX 50s with 26mm Turbo Cotton tyres.
