Thanks all.

I had the idea this was one of those topics that, if you have to ask, the answer is no.

Just to add some color - I am looking for an affordable frame with canti brakes for ss cx racing but also compatible with 700c rims (I have a set I want to use) and horizontal dropouts so I can easily put back to a geared bike in case I hate racing ss or make it a touring bike in case I hate racing period (currently I only have my ss commuter, nothing for longer rides)

I will either have to make due with a 1/2 link setup or the eno hub by White Industries mentioned above or build a couple dedicated bikes.
