Tacx Antares rollers feature conical rollers so your ride will be extra stable. With the Antares you can now focus even more on your goals in training: improve your fitness and pedal stroke and reinforce your sense of equilibrium at the same time. When you ride without the brace you will need to concentrate. Tacx Antares rollers distinguish themselves through the heavy conical rollers that create the momentum of mass inertia. When collapsed the rollers measure only 80 cm and are therefore easily transportable.
