I didn't quite understand why my fixed (170 mm, miche BB, miche cranks) felt more comfortable than my tourer (also 170 mm but a triple...and a wider BB). As my left knee occasionally niggled slightly. So I moved the cleats in on my second pair of shoes which helped.
Well, I suspect it's the Q factor. Now obv. the difference between a track frame/bb and a triple frame/bb is going to be massive, but if you find despite cleats, saddle etc. adjustment something still doesn't feel like, may be worth looking into Q factor. Perhaps your new frame has a wider BB, crank spacing etc...
One observation on my part...
