The 2019 Specialized Tarmac Disc Pro is a light & stiff carbon road race bike with aggressive geometry, carbon rims & a Shimano Ultegra Di 2 groupset. Whether youre racing friends on the weekend, snagging a new KOM or PR, or mixing it up in a local road race, the Tarmac Disc Pro it the purpose-built to do it with. In order to cut some grams from the Tarmac, but to also ensure that its stiff & compliant in exactly the right places, Specialized took major improve their Rider-First Engineered™ technology. From different layup schedules & materials, to visibly different forks, they scrutinized every single aspect of the Tarmac to ensure youre getting the perfect ride. With this revamp, Specialized also updated the geometry, basing it on countless Retül data points & professional rider input. This enabled them to develop a Performance Road Geometry that perfects the combination of a responsive front-end & short wheelbase, which delivers instantaneous response & optimal power transfer. & while stiffness aids in the aforementioned, compliance must also be utilized for an optimal ride quality. Thats why Specialized designed a seatpost that builds compliance into the upper 120mm where clamping doesnt happen, dropped the seatstays, & altered the seat tube shape. They also added tyre clearance up to 30mm, which translates to a 28mm Turbo Cotton on a Roval CL 50 Disc wheel. This allows lower pressures for decreased rolling resistance, increased traction, & more comfort. Altogether, these additions still have the Tarmac riding like a true race-machine, but it also takes a bit of the sting out of road imperfections. Youll thank us on your next long ride. But why disc brakes? The real question is "why not?" They offer superior braking power & modulation, work exceptionally well in wet weather, & offer a very, very minor weight addition. All this means that you have more control & can go faster with more confidence. Aerodynamic improvements are the most important thing to make you faster. Specializeds Bora-Hansgrohe & Quick-Step Floors Pro Tour riders, after all, are demanding aero improvements on every bike. With this, the aero goal was to discover where they could essentially "add aero for free, " by not taking anything away from the hallmarks of the Tarmac design. During the six-month iterative process, three areas were discovered where they could do this—a new fork shape, dropped seatstays with aero tubes, & a D-shaped seatpost & seat tube. The result? A bike thats Approx. 45 seconds faster over 40km compared to other lightweight bikes in the same category. The spec on this Tarmac means business, with Shimano Ultegra Di 2 handling shifting duties, powerful hydraulic disc brakes, & lightweight & aerodynamic Roval CL 50 Disc carbon wheels.
