These revolutionary new rollers by Tacx move with you as you ride! You're able to sprint, stand up, and have a blast without the fear of falling off. You have all the freedom of movement you want, providing you with a realistic riding sensation. The kinetic energy produced when you accelerate moves the trainer forwards, and the reduction in speed after moves the trainer back again. This invention is so unique, it has been patented by Tacx.
