Descend faster and sprint harder than you ever thought possible on the Specialized Tarmac Pro Ultegra UDi2. This road rocket boasts a FACT 10r carbon frame and fork that are super light to float up climbs, and exceptionally stiff to handle out-of-the-saddle accelerations. Aiding in your quest to hit max velocity are lightweight, aerodynamic carbon Roval wheels and an undeniably extraordinary Shimano Ultegra Di2 electronic drivetrain with a mid-compact crank to get you up lung-testing climbs and down will-testing descents. To reign in all that speed, this Tarmac comes equipped with Shimano Ultegra brakes for all-conditions stopping power. And, from training sessions to race day, you'll be glad the Tarmac Pro Disc Race is topped off with Specialized's world-class components. Even your saddle has carbon rails to keep the weight down so you'll be ready when the road turns up.
