Maybe some previous owner had two bikes, one with 32's and the other with 36's. Wanting 32F and 36R, he swapped them and sold you the extra.
But I speculate.
Nah, they were on an old bike we found in the trash.
Has anyone seen a bike with 36f, 32r? Would it look stupid? As I have a 36f and a 28f, I was thinking I'd build up the 36 right away and continue my search for a 28-hole rim.
