I just got off the phone with Tim (Head Honcho at Sulky). I was calling to verify my order and we fell into a more or less single sided conversation (He was nice, but I talk alot). Anyway, He was very interested and excited about the unintentional niche following these tires have and he expressed to me that he , himself, has been bitten by the Rat Rod bug.
When I apologized for talking too much, he just said he was basically learning and that he plans to be doing his own Rat Rod bicycle build.
He also said he was still looking into getting these things in a white wall version for you white wall guys out there.
