These revolutionary new rollers by Tacx move with the rider. He can
make sprints, stretch his legs and stand on the pedals without having to
be afraid to fall. He can move more freely, because training on the
Galaxia approaches the natural feeling of the road. Thanks to the
kinetic energy that is created during accelerating, the trainer moves
forward. When slowing down, the trainer moves backward again. This
invention is so unique that is has been patented by Tacx.
How the movable Galaxia works
Stand on the pedals without having to be afraid of falling, stretching legs and making sprints...all of this is possible with the Galaxia which moves with the rider and approximates the natural feel of the road. Exactly how do these revolutionary rollers of Tacx work and what is the major benefit for cyclists?
Thanks to the Galaxia the rider can move more freely. Due to the kinetic energy that is created during accelerating, the trainer moves forward. When slowing down, the trainer moves backward again. At first sight the "swing system" on the Galaxia looks slightly wobbly, but it has the opposite effect. This invention by Tacx enables the rider to actually stay on the rollers more easily. This invention is so unique that is has been patented by Tacx.
The Galaxia works better than comparable rollers that have the trainer moving forward via elastomers, but which provide an unnatural feeling when slowing down. The new roller of Tacx is designed to give the rider additional freedom of movement. According to John Zwinkels, the creator who based his idea on physics, this is where the power of the Galaxia lies. Using three examples, he explains why the Galaxia is so exceptional.
1. Outdoors on the road there are three variables: the movement of the rider, the movement of the bicycle, and the stationary surface of the road. With a jump, the rider moves and the bicycle accelerates forward. The bicycle wheels rotate faster because of the stationary road. However, the forward jolt is absorbed by the freedom of movement of the bicycle with regard to the rear wheel and the pavement.
2. With standard rollers the three variables are: the movement of the rider, the stationary bicycle, and the stationary roller. The rider must remain seated to allow the wheels to properly roll on the rollers; he has to pedal smoothly. The rider immediately senses the forward jolt on the saddle if he does not pedal smoothly, and there is the risk of the bicycle 'derailing'.
3. The three variables with the Galaxia are: the moving rider, the moving bicycle and the moving roller. With this the jolt is absorbed by the forward freedom of movement of the bicycle and the forward moving roller. This combination of freedoms of movement of the bicycle and the roller closely approximate the sensation of outdoor cycling. This is all due to the unique swing system of the Galaxia.
