Just like you, the Tacx Flux Trainer is getting stronger over time. It's now upgraded with a heavier flywheel to give it a more realistic road feel. The resistance got a tweak to make sure you never reach its max level. At maximum 2000 Watts and 16% simulated incline, it's a given that you'll tap out long before the trainer does. Design-wise, it also has lowered front legs so it clears long-cage derailleurs.

Direct drive trainer ensures that every Watt you generate is accounted for
