The Tacx Flux S is incredibly stable, thanks to its large footprint and hefty weight.

The V-shaped legs provide a wide stance for lateral stability, and the overall unit is very grounded (Image credit: Mildred Locke) Once all these devices were hooked up, I added a Garmin Rally power meter to test for accuracy, and I was good to go. Being part of the Garmin family, the Tacx Flux S (and all of Tacx’s smart trainers, for that matter) connects seamlessly to the rest of the Garmin ecosystem.
#Flux apartments price Bluetooth
As you’d expect from any smart trainer nowadays, the Flux S uses ANT+ and Bluetooth to connect to various devices, and I found it extremely quick and easy to connect with my Garmin Venu, Garmin Edge 830 and Zwift on my laptop - my cheapest Zwift setup. The startup is as simple as plugging it in and pedalling. Once your bike is installed, you’re pretty much ready to go. I was able to work around this, as it’s only a slight overlap, but it’s worth bearing in mind if you’re using an older bike. One minor hiccup I experienced almost immediately was that when I installed my circa-2017 road bike with post-mount disc brakes, I found there was actually about 1mm of overlap between the post mount adapter and the trainer. Thanks to the supplied quick-release skewer and thru-axle adapter end caps, the unit is compatible with almost any road bike or mountain bike, including those with Boost rear spacing. The Flux S is a direct-drive smart trainer, meaning you remove your rear wheel and mount the frame directly to the unit via the dropouts. Take care when mounting older road bikes, as there was a slight overlap between the trainer and this post mount disc brake adapter (Image credit: Mildred Locke) Instead, it’s a full-body effort to lift the thing and plonk it down in a spot where it will probably stay until the end of time, because you’re not going through all that again any time soon. Once assembled, it’s time to put the Flux S into position, and that’s when you realise it has no carry handle, or really anything you can grip one hand around easily in order to move it from one place to another. It’s also quite large, measuring 67cm long, 46cm high and 64cm wide. Once they’re attached, provided you’re on stable ground, they won’t budge at all, making the Flux S a sturdy and solid indoor trainer, albeit quite a hefty one at 20.9kg.

The leg design is clever, forming a ‘V’ shape that provides lateral support.

From here it's easy to attach the legs and secure them.

We recommend that you install the cassette prior to the legs, as it’s much easier to lay the main body sideways and slide the sprockets into place. The supplied quick-release axle can work with both 142mm and 148mm widths, and there’s a 135x10mm adapter available for cyclocross and mountain bikes.
#Flux apartments price driver
The Flux S is immediately compatible with Shimano and SRAM cassettes from eight- to 11-speed, and you can buy a SRAM XDR driver or Campagnolo-compatible body separately. Not included is the cassette, so you'll need to supply your own, and you’ll also need to supply your own chain whip and lockring tool to attach it.
