Nice! What size are those rear wheels, and did you have to use a hub adapter? I've seen those before but could only match the size for the fronts. Almost to fancy for the riding I do thou, but they look sweet!
The backs are 20s. I had to get 144 to 110 adapters which gave me an extra 3 inches on the wheel base. It looks even bigger than that bc the fronts are narrow. Got a great deal though tires and rims for $450 and they weren't even dirty, practically brand new. Adapters are also ITP got them from KG Moto tires online for $85.
