BrazAd you can make a better value proposition looking at aluminum wheels, for example the Spinergy GX, which are $740, wider internally, and 1.5lbs lighter. You also gain the comfort benefits of the PBO spokes…oh, and you can pick a complementary spoke color! I’ve been running GX the past 11 months or so, and they’ve been great under my 240lbs mass, but there are other options, too, like the HED Emporia GA Performance, which is also wider internally than the i23, 1665g for the wheelset, and $750.

That said, deep section carbon rims are stiff, strong, and aerodynamic, so those are potential benefits, though wheel strength is not so much an issue these days I think.

Aesthetically, a strong case can be made for aero carbon rims, too.
