Booster  T2500

Prepare yourself in a professional manner and get your body in top condition with the Booster, the top model of the Tacx cycletrainers. Even at low speed the powerful magnetic brake generates high resistance; the maximum resistance is 1050 Watt. This makes the Booster highly suitable for simulating climbs and for interval training with short, intense sprints. The handlebar resistance lever allows you to set the level of resistance by selecting one of ten different positions. The brake is easy to assemble so you can get started straight away. The professionals with whom Tacx cooperates use the Booster for warming up for time-trials and other important stages. ‘‘The Booster gives me the same feeling like I have on the road”, says multiple time-trial world champion Tony Martin.

1 Flywheel effect: the higher the value, the more realistic the cycling experience

The magnetic brake has a simpler braking system and is therefore ideal for straightforward training sessions such as warming up before a race and endurance training. The road is simulated using different positions that you adjust yourself.

Thanks to its advanced magnetic brake the Booster generates very high powers at low speeds. The integrated braking system consists of two discs with 8 permanent-magnets each and a 2 kg flywheel. It can reach a maximum resistance of no less than 1050 Watt. The Booster is easy to assemble and also safe, because the brake has been built in to prevent the rider from contact with the hot flywheel.

Do you have a basic trainer? Then all you need is a speed sensor to be able to train with your smartphone or tablet! 

Many training software programs, such as Tacx, Zwift and TrainerRoad, work with Virtual Power. To do so, your power is calculated using your speed and the resistance level of the linked trainer. You, yourself, indicate what position the basic trainer is in and the linked speed sensor transmits your speed. The software then calculates what your power is. Virtual Power is less accurate than measuring your power directly, but sufficiently accurate for these programs. 

Every trainer has its own power curve, certain speeds linked to certain power values. The various training software packages have the power curves of all Tacx trainers. If you use Virtual Power, you must make sure that every time that you start training, both the pressure between the rear wheel and the trainer and the pressure in your tyre are linked. If they are not linked with one another, inconsistencies will be introduced into your measurements.  

The following software packages work with Virtual Power and the Booster:

  • Zwift
  • TrainerRoad
