what’s the wisdom of making these have generally small chainrings?
There's no wisdom, just tradition and a desire to save a little money and weight. The primary drive rings, whether crossover or straight through, take no more load than those on a solo.
The limit is going to be chainstay clearance, up to that point going bigger is a good thing for smoother drive and slower wear.

Hi all
Want to ask a general question about crossover cranks... what’s the wisdom of making these have generally small chainrings? The stronglight Left pair of cranks I’m re-using have 34t rings, the wear is pretty heavy and I was thinking about using much bigger rings. Is it a strength thing, i.e. bigger rings more likely to fail under the various combined forces of two riders?
