I have the "Pro" wheelset from 2001: Zero hubs, 28F/32R, bladed spokes. I've put at least 5000 miles
on them without much trouble. I do believe that the blades and aero profile of the rim make a
difference. Good qaulity overall though they seem to have a bad reputation and are not very common.
However, the rear wheel does feel a little soft when pushing *really* hard. Perhaps the narrow
flange width is too narrow to provide a good base for support?
I did break a spoke, though I think it was due to an improper truing, so I do it myself now. One
quirk: I have found that spokes can slowly work themselves loose at the nipple. I just take the time
to check them every 4-500 miles to be sure everything stays nice and tight. No problems since.
Maintainable with normal tools, durable, aero, regular nipples, reasonable weight, can replace
broken spokes with regular round one in a pinch... what more could you want?
