The Tacx Flux is a compact and realistic interactive direct drive trainer. It is maintenance-free. The instantaneous response of the Smart electronics and the 7 kg flywheel adjust the slightest fluctuations in resistance directly and accurately to your legs. The Flux does not require a front wheel support because the trainer is already adjusted to the height of the bicycle.
The Smart Flux connects wirelessly via ANT+ or Bluetooth to smart phones, tablets and sports watches which make it possible for third-party applications like Zwift and TrainerRoad to control the user experience. The technology also allows for multiple devices to be connected simultaneously. The unit has three simple LED lights on the side to alert you when it is connected to power and ANT+ or Bluetooth. If technology is not your thing, the trainer can still be used on its own and will simulate a flat road.
The unit has compatibility for road and mountain bikes to be connected with quick release skewers supplied in 130mm and 135mm lengths. Tacx state adapters are available for other rear widths and axle types, however, point out that bikes with long cage rear derailleurs won't fit into the unit. Regardless of your choice of cassette, the Smart Flux can likely accommodate it. All 9, 10 and 11-speed cassettes from SRAM and Shimano are compatible, as are the majority of Campagnolo cassettes, aside from 9, 10 and 11-speed Centaur and 10-speed Veloce. Spacers, 11 and 12-gear lock rings, and a hex key is provided so you should be up and going in no time.
