The Tacx Flux Smart Turbo Trainer T2900 is the most accessible direct drive turbo trainer on the market today with an electro brake that dramatically reduces the trainer's decibel level whilst also creating a realistic and highly adaptive feeling of resistance. Bluetooth+, FE-C and ANT+ compatible, this trainer can be used with a wide range of apps and virtual training programs.

Tacx Flux Smart Turbo Trainer T2900

The Tacx Flux Smart Turbo Trainer T2900 offers a compact and highly realistic interactive direct drive turbo trainer. With a highly responsive 7KG flywheel and electro brake technology, this trainer produces a realistic and highly customisable riding experience.

Of all turbo trainers in the Tacx range, the Flux has the heaviest actual flywheel with an effect of 22.8kg. This ultimately creates a more realistic riding experience and with the use of ANT+ and Bluetooth connectivity, the trainer can communicate wirelessly with your smartphone, tablet or PC (requires Tacx Upgrade Smart dongle). This connectivity also allows the Flux to be connected to apps like the free Tacx Training app of smartphones or tablets or the Tacx Trainer software on the PC (available separately). Third-party apps like Strava, Swift and Trainer Road are also compatible.

Tacx has also integrated their cutting-edge electo brake technology into the trainer. By placing magnets and electro magnets beside a rotating aluminium disc, electromagnetic currents are created which generate an opposing magnetic field. In this way, a non-contact, maintenance-free brake is realised that is also silent. Thanks to the electro brake, a resistance can be set that you also experience on the road or in a climb.

With a realistic slope incline up to 10% and a max wattage resistance of 1500 watts (for 10 seconds), this trainer is perfect for riders who want to test themselves on the climbs or thrash out their best sprint performance.


The FLUX has a universal EDCO Multisys body that fits all Shimano and SRAM cassettes, and most Campagnolo cassettes. Whether it fits depends on the amount of cutouts inside the cassette. Campagnolo cassettes with 8 cutouts, like the 10 speed Veloce, will not fit, unfortunately. Below is a list of what fits and what doesn't fit:

  • Shimano: All 9-speed, 10-speed and 11-speed models
  • SRAM: All 9-speed, 10-speed and 11-speed models
  • Campagnolo 9-Speed: Centaur, Ghibli (11 drivetrain)
  • Campagnolo 10-Speed: Record, Record Ti, Chorus, Centaur 2009, Centaur 2011
  • Campagnolo 11-Speed: Record, Record Ti, Super Record, Super Record Ti, Chorus and Athena

Please note: To connect the FLUX Smart to your Windows computer, the Upgrade Smart is required. Cassette (pictured) is available separately. It cannot be used with long cage rear derailleurs.
