The Tacx Flux S Smart T2900S turbo trainer is known for its excellent price-quality ratio. It’s ideal for road cyclists and mountainbikers looking for a reliable trainer so they can keep training indoors.

The Flux S Smart trainer is the successor of the popular Tacx Flux T2900. Now that the shape of the Flux S has been adapted, it is also suitable for road bikes with a long cage derailleur. Also, the Tacx Flux S' motor has been further improved to make it even quieter during training sessions.

One of the quietest turbo trainers available
The Flux S Smart is one of he quietest trainers out there. Therefore, it is the ideal trainer to use in a noisy environment.

The Flux S Smart’s integrated power meter has an accuracy of up to 3 percent. This makes it ideal for cyclists who love to train with FTP, wattage and Watt/kg.

Wide range of training options
The Flux S Smart has a maximum resistance capacity of 1500 Watts. In addition, the Smart S can simulate inclines with a percentage increase of up to 10%. The electronic brake enables automatic adjustment of training resistance. This allows you to precisely simulate climbs for a very realistic experience.

Connecting to software and devices
With ANT+ and Bluetooth signals you can quickly and easily connect to other devices, applications and software. Thanks to the ANT+ FE-C protocol you can allow for the turbo trainer to be controlled by Tacx apps or third party apps like Zwift. The trainer can also be used stand-alone. When it's not connected to other devices or software, the Tacx Flux will simulate a level road.

The Tacx Flux S Smart T2900S is an excellent choice for cyclists who want to keep training during the winter months.
