Yeah, but 700c 9sp. with wide enough rims that aren't aero road rims = not easy to find. I want to run 35-42 tire size. I found a set of Velocity A23, that takes a 9sp. cassette, and not super narrow. They might work. Most of the wheels I "could" buy are disc brake hubs, and no braking surface. 29er's or CX. Sometimes up to a grand a set which is ridiculous for a bike I spent $92 on. The super reasonable ones all seem to be freewheel threads. 7 speed is the absolute maximum for a freewheel in my humble opinion. At an average of 230+ body weight, I would snap hollow 7 speed axles in two on a semi regular basis.
