My SS bike has semi-vertical (or is that semi-horizontal?) dropouts: they are angled downward (in a forward direction) to allow the rear wheel to be removed easily even with fenders (which can be a problem with horizontal dropouts), but they are still horizontal enough to allow me to get enough chain tension by just pulling the wheel back while tightening the locknuts. There's not enough fore-aft adjustment to allow me to change the freewheel size without sizing a new chain, but that's fine - I have never felt a need for a change in gearing.
