Yep, I've definitely ordered a wheelset that as of yet is not compatible with my bike. The bike is a Cruzbike Q45. The back wheel fits fine in the bike's drivetrain side.
But this wheel with the problem goes on the back of the bike, and the dropouts there are only 100mm wide.
If someone can provide guidance on how to convert from boost to non-boost, that'd be great. I don't know what to look for or how to perform the procedure.
If no help is available here and if it's not possible for me to perform the work, I think I'm going to have to ask the local shop to rebuild the wheel for me because I discarded the box from Aliexpress and I think I'm pretty well past the return window anyway.
