Cycling Weekly Verdict

The single-sprocket design of the Zwift Hub One direct drive smart trainer gets around the toothy issue for users and manufactures of multiple cassette options. By replacing the usual cassette with a single-sprocket and resistance changes with a virtual shifts, Zwift has removed the cost and hassle issues of swapping bikes on a trainer and improved compatibility for some more niche drivetrain options. The system works well and, even though it loses something in feel, the virtual shifting offers some additional advantages such as evenly spaced resistance changes.

At the time of launch the Zwift Hub One was the second of Zwift’s two direct drive trainers. Or, to be more precise, it was one of two versions of a single trainer. Fast forward a few months and now the legal dispute between Zwift and Wahoo has been resolved, the Hub One is Zwift’s only trainer.

Whereas the standard Hub used a standard cassette for gearing and resistance, the Hub One features a single sprocket and virtual gears. The minimalist design makes the Hub One compatible with any 8 – 12 speed drivetrain and so removes user cost and hassle in buying and swapping cassettes and freehubs for different set ups. This sets it apart from the rest of the best smart bike trainers
