If you're obsessed with phenomenal performance look no further than the Specialized Tarmac Pro with Shimano Ultegra Di2. To get the weight around 950 grams, Specialized utilized advanced aerospace composite optimization software to revolutionize the construction and layup of FACT 10r carbon. Specialized has develop a performance road geometry that perfects the combination of a responsive front end and short wheelbase, delivering instantaneous response and optimal power transfer. And while stiffness aids in the aforementioned, compliance must also be utilized for an optimal ride quality. That's why Specialized designed a seatpost that builds compliance into the upper 120mm where clamping doesn't happen, dropped the seatstays, and altered the seat tube shape. They also added tire clearance up to 30mm, which translates to a 28mm Turbo Cotton on a Roval CL 50 wheel. This allows lower pressures for decreased rolling resistance, increased traction, and more comfort. Altogether, these additions still have the Tarmac riding like a true race-machine, but just takes a bit of the sting out of those road imperfections. The Tarmac Pro comes spec'd with Shimano's Ultegra 8150 Di2 groupset with direct mount brakes and the affordable, yet impressively aerodynamic, Roval CL 50 wheelset with 26mm S-Works Turbo tires.
And while this is all great, Specialized's knows that aerodynamics are the most important thing they can do to make you faster. Both Bora-Hansgrohe and Team Quick Step Floors Pro Tour riders, after all, are demanding aero improvements on every bike. During the six-month iterative process, three areas were discovered where they could do this—a new fork shape, dropped seatstays with aero tubes, and a d-shaped seatpost and seat tube. The result? A bike that's approximately 45 seconds faster over 40km compared to other lightweight bikes in the same category. A speed savings that you'll feel when you're attacking off the front of the peloton.
- The FACT 10r carbon frame combines the lightweight performance and compliance of their top-end carbon production methods with Rider-First Engineered design that ensures every frame size has the same legendary climbing responsiveness and descending prowess you'd expect from a Tarmac.
- S-Works full FACT carbon fork with a tapered construction provides incredible front end stiffness and steering response for instantaneous accelerations and high-speed descents.
- A 52/36T S-Works alloy crankset is incredibly stiff, with a chainring grouping that's equally suited to big alpine climbs as it is to throwing down the gauntlet on the flats.
Electronic drivetrain systems deliver excellent shifting, easy set up, and solid battery life. Here are some benefits of electronic shifting that you don't want to miss.
Electronic shifting systems use powerful servo motors to rapidly shift the chain. Because microprocessors and sensors constantly monitor every aspect of the system, they shift with surgical precision and without chain rub.
Many major systems have customizable shifting. Some have the ability to add remote shifters for common riding positions, and some even allow you to change the functions of the shifting buttons.
Electronic groupsets are responsive and consistent. There are no cables to stretch and wear out, so you get a flawless shift every time. The added bonus is you'll never have to replace a derailleur cable ever again.
