Specialized S-Works Tarmac SL6 Road Bike 2018
Instantly conjuring victories and pro-peloton performance, Tarmac has become a name that embodies the most dedicated and driven approach to road cycling design in recent years. With the Specialized S-Works Tarmac SL6 Road Bike 2018 the latest in the line of premium performance, pedigree race machines from this world renowned brand, you can be sure of the most rider tuned, dialled in design to date.
An all-new frame design taking inspiration from the success of the Venge and Roubaix, the new Tarmac aims to be lighter, faster and smoother than it's predecessor. Constructed from Specialized's own 12r FACT carbon fibre for astounding stiffness to weight ratios, the latest Tarmac comes in at a full 200 grams lighter than the previous iteration, a truly astounding development in performance at the very highest level.
A redesigned and dropped seatstay bring this bike closer to the profile of the original Shiv Time Trial bike, sheltering the seatstays at their juncture with the seatpost and boosting the aerodynamic performance with no cost to the responsive feel of this bike. The frame incorporating for the first time a D-shaped seatpost and seat tube for improved aerodynamic prowess, this design further improves the level of comfort that you benefit from on your ride. Engineered flex added near the top of the seatpost means that you lose no power, whilst gaining crucial movement that makes those all-out efforts replicable.
Rolling on Roval CLX50 wheels for the best possible balance between lightweight responsiveness and all-out aerodynamic speed, the Tarmac SL6 benefits from a strong and high-quality carbon fibre construction, assuring you of the most direct transmission of your power possible.
Equipped with a full Shimano Dura-Ace Di2 9150 groupset for peerless electronic shifting, your riding need never suffers from mechanical misfiring again. Gliding across the rear cassette with the lightest possible action, this component choice provides supreme levels of adaptability and customisation, allowing the discerning rider the ability to call the shots.
