I am interested in purchasing a Zwift hub , but I am doubting whether the thru axle of my bike would be compatible. My bike is a Scott Speedster Gravel 30 (2022 edition) The zwift support site mentions that 142mm and 148mm thru axles would be supported, but my thru axle seems to have some very unique dimensions (see below) that I cannot find on any other bikes. Can you tell me whether there is any chance to run this thru axle on the Zwift Hub?
Length: 157.5 MM
Thread length: 13.5 MM
Thread pitch: M12*P1.5
Sorry that you haven’t had any replies, yet. I don’t have the answer either, despite trying to research it, but am bumping this in case it reaches eyeballs with more knowledge.
If you get a definitive answer, perhaps through contacting Zwift support directly, please do post back here.
142 and 148mm are the over-locknut dimension of the hub, not the dimension of the thru-axle. Try measuring the distance between the inside of the dropouts on the frame. I would guess it’s 142. You could also ask the manufacturer. It’s unlikely to be weird since it appears to be using standard components and it would be a little crazy for them to design a bike that can’t use a standard size replacement wheel.
thanks for your replies! That makes perfect sense. I have checked the distance between the dropouts and as you already assumed it is indeed 142MM. I was a bit confused because the support site has one section each for dropouts widths and thru axles and mentions the lengths in both sections. I compared the effective length of my thru axle with the widths indicated in the thru axle section instead of looking at the over-locknut dimension
