De Rosa TT-03 Disc Triathlon Frame

Unleash Your Potential with the De Rosa TT-03 Disc

When you have done all the training possible, you’ve optimized your diet, you’re getting enough sleep, there is only one thing more that you can do to improve your time trialling and triathlon performance: invest in a fantastically aerodynamic time trial bike. The De Rosa TT-03 Disc has been developed for the modern racer looking not only for aero performance but a lightweight, reasonably comfortable ride.

If you are in the market for a time trial bike, you must take your time trial or triathlon racing very seriously. You can rest assured that De Rosa takes the design equally seriously, not only because they want to make their customers happy, but because they have professional teams to keep happy as well. And that’s a good thing since it means the TT-03 Disc has been road tested by the pros and then optimized to suit the needs of every day cyclists like us.

Don’t think that this is a simple update with disc brakes compared to the rim brake version of the TT-03. Aside from adding the disc brakes, De Rosa’s engineers have focused on improving everything from the aerodynamics to the weight to the rigidity. For the aerodynamics of the frame, removing the cables in the front needed for the rim brake made a huge difference in being able to clean up the lines and open up the front end of the fork in particular. That makes the free flow of air around the rotating wheels much less an issue in terms of drag. The head tube transition to the top tube with the integrated cockpit has also been given a very sleek design to help it slice through the air more efficiently.

Rear Triangle Optimization in the De Rosa TT-03 Disc

The rear triangle retains that very distinct rounded seat tube that tightly hugs the rear wheel, helping to smooth the airflow coming off the rider’s legs. But the rear end is always less about aerodynamic gains and more about frame stiffness. And that is an area greatly improved by the De Rosa engineers for this disc brake version of their time trial bike. They have increased the use of high modulus carbon fiber to help increase stiffness and reduce weight at the same time. The resulting improvement in power transfer will make a difference in every pedal stroke.

With an eye towards the triathlon market as well as the time trial, they have made the front end quite adjustable when co-developing the Vision TFA aero cockpit. The internal cable routing adds a lot to the overall cleanness of the sleek setup but offers a level of practicality since it is compatible with electric and mechanical shifting. That’s something that is being slowly phased out, with many manufacturers accommodating just electric drivetrains. But many of us who like sticking with the tried and true mechanical drivetrains like to see a little love still shown.

The De Rosa TT-03 Disc offers a level of performance that will see you slash your race times. It’s been designed to suit racers who demand the highest quality in all their equipment.
