Tacx improves Flux Smart Trainer AND reduces price

Tacx is releasing an updated version of its Flux Smart Trainer, the new Flux S coming with an altered design that makes it compatible with long cage derailleurs, and improved power measurement. It is also much cheaper than before at £549.

If recent stormy weather has convinced you that it's time to batten down the hatches and think about training indoors, this looks like a great deal, especially when you consider that the previous Tacx Flux Smart Trainer was £699.99 — and that was very good value.

We were impressed by the Tacx Flux Smart Trainer when we reviewed it last year, but we did think it was odd that a long cage derailleur would catch on the body of the unit in some gears. Tacx says that it has addressed this issue with the Flux S, and has also altered things under the bonnet.

"The internal mechanics of the Flux S Smart are redesigned to improve the power measurement," says Tacx. "Because of this, the trainer is reliable, accurate and consistent and calculates your power accurately within 3%. 

"The internal upgrade together with the heavy flywheel of 7kg (15.4 lbs) [the previous version had a 7kg flywheel too] improves the ride feel significantly. This direct drive trainer is designed to bring vibrations and noise levels to the absolute minimum, resulting in the most silent flywheel-equipped bike trainer available."

We remarked in our review of the previous Flux Smart Trainer that it wouldn't disturb the family watching TV in the next room.

The Tacx Flux Smart Trainer comes with ANT+ (FE-C) and Bluetooth Smart technology so you can connect it to Zwift and the Tacx Desktop app, for example. Connecting to the Tacx Utility app allows you to update the firmware to take advantage of any new improvements and features. You can also use it without any software connections.
