Wanted: Small or XS(48cm?) gravel frameset like an arkose or similar. Maybe a complete bike.

You'd struggle for 5ft3 and 52, defo looking at 48. I'm 5'7 and ride 52 (and could go down to 51). Just got my partner (also 5'3) a bike and 48s seem pretty rare round these parts owing to preponderance of male forumites, all the best with search.
