About this item

  • The FLUX 2 Smart is equipped with a stronger resistance unit and a heavier flywheel to increase the maximum resistance to 2000 Watts.By positioning the additional weight of the flywheel strategically, the FLUX 2 Smart gained a higher mass inertia. This improves the ride feel significantly and makes every pedal stroke very smooth.
  • By supplying the FLUX 2 Smart with extra axle adapters, the axle compatibility significantly increased. The FLUX 2 Smart is compatible with 142x12mm and 148x12mm, straight out of the box. Just like the internal structure, also the exterior of the FLUX 2 Smart has been redesigned completely. By creating more space for the derailleur cage, it is also compatible with long cage derailleurs.
  • The internal mechanics of the FLUX 2 are redesigned to improve the ride feel and the power measurement. A reliable, accurate and consistent power measurement is key to keep track of your performance and progress. This is exactly what the FLUX 2 Smart is designed for, measuring your power accurately within a 2.5% range.
  • Intuitive LED’s on the side of the FLUX 2 Smart show when the trainer is powered and connected to a device over ANT+ or Bluetooth. The smart electronics of the FLUX 2 Smart allow you to train stand alone, without any software connections. The resistance follows a progressive power curve, in accordance with cycling on a flat road. Speeding up means an increase of resistance.
  • With the Tacx Utility app you can easily update the firmware of the FLUX 2 Smart to the latest version, so you can always make use of the latest improvements and features. You’ll get notified when an update is available.

1 week in - working well. Here's some setup details all in one spot!
This trainer works great. It immediately connected to the software (iPhone Xs) via bluetooth.Personally, I am enjoying the rides offered in the Tacx software and will probably pay for a subscription. Pretty rides all through Europe.I want to re-emphasize the setup of the trainer because even after reading lots of reviews, I still missed a few nuances.You will need a sprocket cassette - if you also ride on the road a lot, just buy another cassette that is identical to the one on your road bike. Pull the rear wheel off your road bike, look at the model number on the cassette lockring. Order that.Also - ***You need the spacers that go behind the cassette.** For a Shimano 10 speed cassette, there is a 1.85 mm and a 1 mm spacer - you need both of them. Trust me. If you don't get it right, the bike won't shift properly.You need a torque wrench and cassette removal tools.If that is somewhat confusing, it looks like local bike shops are becoming used to set these up for people. Take the bike and the trainer to your LBS and throw them some business. BTW - I got the spacers I needed locally for a few dollars. They are quite a bit more $ on Amazon.With a duplicate cassette installed, you can now decide at a moment's notice to take your bike outside - just pull it off the trainer, slap the back wheel on, and get your bad self on down the road.One note - to make the shifting work properly on both, I had to *slightly* adjust the rear derailleur so that it was inboard a slight amount. That's the adjustment nut on the end of the shift cable at the derailleur. Now it shifts correctly both on the trainer and road wheel.
