I am considering purchasing the Zwift Hub to start using Zwift. I have a 3xs bike from Canyon, which has a seat tube length of 40cm. It doesn’t seem to fulfill the minimum required frame size of Zwift Hub. Does anyone has experience using a small bike like this on the Zwift Hub? Or know that which indoor trainer is compatible with this bike.
Some frames will be incompatible with direct drive (i.e. rear wheel off) trainers in general, not just Zwift Hub. The length of the seat tube is not typically where you’ll run into clearance issues, it’s more likely the rear dropout / brake caliper area on the non-drive side, or the rear dropout / seatstay / chainstay on the drive side.
