Well, I got two of these... Panaracer GravelKing SS + Plus ProTite 700x28 Semi-Slick Tire
Last time I raced Boulder Roubaix, I thought I needed to be fast on the road and the gravel would just be survival. I was wrong... The road was slow, the gravel was like a crit. At midnight. I hope these help a bit.
You should find a couple other guys that want to kill it on the tarmac, and see how that goes.
