TACX FLUX 2 S UPGRADE
TACX FLUX 2 S SERIES

The Flux 2 provides thru-axle adapters in the box whereas on the Flux S you need to pick them up separately ($29-$39). Also, it can resist 2,000w versus the 1,500w. The main differences between the Flux S and Flux 2 are that the Flux 2 (at $150 more) can simulate 16% grades and has an increased simulated flywheel mass (32.1kg vs 24.7kg). There’s no sound differences between the Flux S and Flux 2. They aren’t silent, but they aren’t loud either. If you’re unsure whether or not you can put out 1,500w…the answer is likely no. The Flux S maxes out at a 10% grade, which is normal for this price point, and maxes out at 1,500w.

It changes the resistance based on what the app sends it, such as 10% grade or 325 watts.

TACX FLUX 2 S SERIES

Essentially, the Flux series is a smart/interactive trainer that works with virtually all apps out there (Zwift, TrainerRoad, Rouvy, SufferFest, etc…).

Now, if you aren’t familiar with a Flux trainer to begin with, I’ve probably gotten a bit off-track. I do a quick walk-through of the trainer here at Interbike in this nice and efficient video: Back in June they dropped the price to $799 for the Flux 1, whereas now we saw at Interbike the Flux S has been dropped even further to $749USD/599EUR (also: 999CAD, 549GBP, 725CHF, 5919NOK, 4619KK). With that change, you’ve gone from Flux 1 to Flux S. – Long derailleur cage support (they dropped the legs lower so that it fits)Īnd that’s it. However, there’s one change that’s coming exclusively to the Flux S: These were applied to the Flux 1 inline over the course of spring. Like I said, not much in the grand scheme of things you can write on the outside of a new product box. – Improved internal alignment (nothing meaningful to consumers, purely manufacturing) – Improved internal tension roller (which results in slightly improved road feel and accuracy during sprints) Specifically, the following mechanical changes were done: However, this past spring Tacx started implementing a handful of changes into the Flux 1 units that would eventually serve as the basis for not just the Flux S but also the Flux 2 as well (which isn’t set to ship for a bit longer). Again, mostly related to QA issues in the manufacturing process to ensure the product was produced as actually designed. In the case of the Flux 1 which got off to a rocky start two years ago with manufacturing quality issues, there were a slew of changes made early in the cycle. Like most products, over time the manufacturing line has quietly introduced changes that make usually minor and largely unseen changes. The product you’re actually interested in today. And now, finally, the original Flux model will be discontinued, likely as making way for the Flux S. I say June, because that’s when most of the changes were incorporated into the product line. Even after that clarification it can remain confusing, as a 2018 Flux 1 manufactured in January will vary in comparison to one made in June 2018. As there’s actually a substantial difference internally between an original ‘2016 Flux 1’, and a new 2018 Flux 1. See, when I use the term ‘2018 Flux 1’, that in itself is confusing. As a Facebook relationship status might say: It’s complicated. But is it really that simple? Not entirely. Let’s be clear about this, the Flux S smart/interactive trainer is nothing more than an original 2018 Flux 1 with different legs. In the meantime, here’s what you need to know about the Flux S. I was able to poke at it during Interbike, and will definitely dive deeper into it later this fall. And one more thing: Unlike the Flux 2, it’s available now. So now you might ask “what’s the Flux S?” Well, in one sentence or less it’s basically a rebranded Flux 1 that has better support for long derailleur cages. It added a number of internal specs including accuracy and the ability to simulate steeper grades for heavier riders.

TACX FLUX 2 S UPGRADE

The Flux 2 was designed to be a beefier upgrade to the original Flux trainer that came out two years ago. The first Flux trainer was announced this past summer at Eurobike, the Flux 2. Last week at Interbike, Tacx announced the Flux S, making it the second Flux trainer announced in almost as many months.
