Make short work of the competition and shatter your personal bests with Specialized's Transition Comp. This triathlon and time trial wonder bike utilizes Specialized's revolutionary FACT 7R N'Aero carbon frame that's manipulated for the ultimate aero advantage, all the way from the airfoil down tube to the rear-wheel cutout to the trick hidden brakes to the wind-cheating, aero carbon fork. Plus, this sweet machine's Mavic Aksium wheelset rolls effortlessly while Shimano provides a mix of their sweet Ultegra and 105 components for top-notch shifting and reliability.

The Transition features an integrated front and rear brake system that has been designed in concert with the FACT carbon frameset to ensure maximum aerodynamics and control. The rear brake is tucked under the bottom bracket (photo) to minimize exposure to the wind. Because this system was designed to work exclusively with the Transition it also enhances control and safety.

The Transition is the fourth time trial machine I have had over the past 10 years and it certainly is the finest. The geometry and short stem provide the opportunity for excellent aero positioning. Performance is certainly commendable-I have achieved average speeds recently that I have not seen when I was ten years younger. Most TT machines can be complicated with unique seat post configurations and tricky aero bars, but the Transition does not suffer from such complications. What can be tricky is the removal and installation of the rear wheel because it has rear facing dropouts, and adjustment of the rear brake, because it is behind the bottom bracket. Another problem that plagues this design and other "curved seat tube" designs is the lack of a second water bottle mount on the seat tube, necessitating the installation of a seat rail mounted water carrying system, or the use of a Camelbak on longer training rides. These three issues are the only reasons I do not grant the Transition design a perfect score. Once it is set up and running though, it is a fast and comfortable ride suitable for short or long events. Stiff at the bottom bracket area, and the fork is strong and predictable without being harsh. The Zipp Vuka bars are very nice, easy to adjust and very aero.
