Soma Cazadero 650b x “50mm” tires.

Mounted but not ridden, never put sealant in.

They’re smaller than the listed size. I get 47.3mm mounted on i23 rims. Got them in a trade but I already have byways in that size and want to buy some thunderbutts. The soma store has them at $70 each, how about $90 for two shipped?
