This rim is off a Schwinn exercise bike. The hub is a track hub, but a freewheel will spin on. Might have to mess with axle spacing. Also THIS RIM HAS NO VALVE HOLE!!!!!!

Rim is clean. 28hole/spoke.

Last 4 pictures are not of this exact wheel, just demonstrating that a freewheel a spoke protector will fit.

Stamped “Schwinn Tubular S-2”
