I suggest you check out road.cc Zwift hub one review. This trainer is now discontinued but is still a great bit of kit and works very well with Zwift as you would expect. Uses virtual gears no cog as fully described in this review. Simple to set up. I'm being open and honest in informing you this unit is discontinued. Dont confuse it with the newer Wahoo cog trainer. Only reason I'm selling is because i have neck problem ruling out fixed position trainer use. Any questions please ask. (Trainer is pictured with my bike mounted on it - which is not included in the sale !)
