The Vortex rearsets should be able to be configure to run any shift pattern, road or race... And after racing with no quickshifter vs WITH one... ha, well, I'll never go back, that's for sure!
I've been running race pattern for ages on road bikes, and I agree with Chubb... wouldn't do it first up in a race. Could end badly. A slipper clutch will deal with a brain fart, but oh man, could be bad when coming out of a corner and down change instead of upshift...
