Zwift broke new ground with its innovative Hub One trainer back in October 2023. Although the best direct-drive trainers have been a massive step forwards compared to wheel-on trainers, their cassettes spelt compatibility headaches for multi-bike households with differing numbers of gears.
The Hub One solves this issue by replacing the cassette with a single sprocket - making the trainer compatible with 8 - 12 speed bikes. The 'gear shifts' are handled in the same way as a smart bike, with remote buttons that adjust the resistance of the trainer - issues of badly indexed gears and crunching shifts become a thing of the past.
