Howdy, looking for opinions on what size bike I should be looking at, given the size of my (previous) bike fit below.
Me: Height 5'6" , inseam about 30" , average flexibility
Bike: Nominal 48cm (XS), Stack: 513, Reach: 370
Spacers: 10mm dust cap spacer + 5mm spacer
Stem: 100mm length at -7*

I am pretty comfortable on this fit/size bike, but wondering if I can do better. Just reading a few internet resources, for my height I *should* be on a nominal 52cm.
Am I actually too big for bikes of this sizing? Am I sacrificing anything being on a smaller frame?

Thanks
