While theres a certain degree of truth in applying terms like "upgrade" or "value" to our Tarmac Comp we prefer to refrain doing so. Why? Because the Tarmac Comp stands on its own two wheels as a bike thats born to perform & able to take your riding & racing to the next level. Like the S-Works Tarmac iterations it features a Rider-First Engineered design that that applies specificity to every tube size & carbon layup for every frame size. This creates the optimal balance of rigidity weight & responsiveness so every frame regardless of size performs just as we intended. Youll also find an identical Gr&-Tour-winning geometry plus a FACT 9r carbon fibre construction thats nearly mirrors what youll find under the likes of Peter Sagan & Alberto Contador. For the spec we selected components that deliver the best bang for your buck stiff reliable DT Swiss R460 wheels a mix of Shimano Ultegra 6800 & 105 & a bevy of Body Geometry components that maximize performance by providing the utmost in comfort. The FACT 10r carbon frame combines the lightweight performance & compliance of our top-end carbon production methods with our Rider-First Engineered design that ensures every frame size has the same legendary climbing responsiveness & descending prowess youd expect from a Tarmac.
