The Tarmac SL4 Comp UDi2 combines all of the complete performance that the Tarmac is known the world over for with the precise electronic shifting of Shimano's Ultegra Di2. Consider it the perfect bike to grow along with you as you explore the open roads ahead. You'll also find an identical, Grand-Tour-winning geometry, plus a FACT 9r carbon fiber construction that's nearly mirrors what you'll find under the likes of Peter Sagan and Alberto Contador. For the spec, we selected components that deliver the best bang for your buck, durable DT R460 wheels, Shimano Ultegra 6870 Di2 shifting, and a bevy of Body Geometry components that maximize performance by providing the utmost in comfort.
  • The FACT 9r carbon frame has all the stiffness and performance you need in a lightweight package, making climbing and descending the best part of any ride.
