Used Tacx NEO 2 Smart Trainer. No issues with it, I’m the only owner. I just upgraded to a newer one that’s compatible with a specific indoor bike, otherwise I’d stick with this one. Includes adapters for quick release rear wheels and thru-axle rear wheels. I’ve used it with Zwift for the whole time I’ve had it, works well.

Does power and cadence +/- 1% accuracy, 25% inclines, 2200 watt max, it moves the freewheel to simulate downhills and you can use it even without plugging it in—your pedaling powers it.

The ultegra cassette on it isn’t included unless you’re interested in getting that too.
