Tacx Flux S Smart Direct Drive Indoor Cycling Smart Trainer

Season:2022

Brand:Tacx

Code:T2900.S

The Tacx S is essentially a developed and refined Flux 1. The Flux S improves clearance for longer cage derailleurs and has some significant internal upgrades too. Both the Tension roller and the alignment of the internals have been improved, yielding better road feel and accuracy during sprints. The fundamental differences between the Flux 2 and the Flux S are to do with output. The Flux 2 simulates gradients of upto 16% vs 10%, can resist a max output of 2000W vs 1500W (and higher simulated flywheel weight) and is marginally better at simulating low-speed climbing thanks to a lower resistance floor. The Flux S is supplied with a quick release only, while the Flux 2 comes with thru-axle adapters

For most, the Flux S will tick the necessary boxes, helping riders maintain and improve their form over the miserable Winter months. The Flux S outputs readings for speed, cadence and power, and is accurate to 3% - a figure that matters little as long as it's repeatable and the trainer is ANT+, so compatible with the bulk of cycling apps like Zwift, Trainer Road etc etc.

If you are looking for your first Zwift experience and need the tools to do it, then the Tacx Flux S should definitely be on your list; it's seriously quiet too, so that will keep your partner and neighbours happy.

Supplied with 1 month of Tacx's Premium software to get you up to speed.

  • Tacx Flux S Smart Direct Drive Indoor Cycling Smart Trainer review by Anthony , on 16/12/2020

    4
    My Tacx Vortex smart trainer died after 3 years use and I decided to upgrade to a direct drive trainer. I choose the Tacx flux S as I had a good experience with Tacx before. The set-up is easy - literally 2 bolts. It is very quiet compared to the wheel on trainer and gives a more realistic feel to riding. I only had initial problems with the Tacx Desktop training app (not the trainer). I had not realised that it would only connect via bluetooth (not ANT+) as in the older TT4 app. So a blutooth HRM is on order. Also, for me the app would not work without an internet connection so I had to buy wi-fi extenders to get a signal in my garden shed training "cave". I have now had the trainer working for 2 weeks and so far all working well. I did try a rival app that does work without internet but I opted for Tacx and this connects to Garmin Connect directly. In summary I am very pleased with the trainer and would recommend, be prepared for some extras if you use the Tacx Desktop app.

  • Hi, Just checking this trainer is compatible with a Shimano 8 speed cassette
    Question asked by Chris on 27/11/2020 19:49:47
    Hi,

    Yes the Flux S is compatible with a Shimano 8 speed cassette when combined with freehub spacers

    Thanks
  • Hi, I’m thinking about purchasing this trainer, but I’m wondering if it’s suitable for use with disc brake bikes? Due to where the callipers are located I was wondering if it would cause an issue. Thanks, Rhys
    Question asked by Rhys on 08/11/2020 12:53:24
    Hi,

    Provided you use the correct adapter for your bike then there should not be aproblem in fitting a disc brake bike to a Flux S Trainer.

    For a more thorough look into it you can email or 'phone the shop and provide specific details of your bike and we can take a deeper dive.

    Thanks
