I'm pretty happy with Easton EA70AX... got them for around $400 24mm internal and put some Donnelly MSO 42's(measure 43.1) on there. Seem built fairly strong and kinda heavy being nearly 1700g. I also have Enve G27 with 27mm internal and WTB Byways ( which measure 47.10 so far @ 40psi) 1320g for the rims.. F'kn ride like a best sofa you ever sat in.
