I have one pair of wheels with OMAS hubs - as
AZORCH notes, they spin like buttah
Also have a spare NOS front hub (for sale) just kicking around, and another C&Ver just received a complete set from me just a week or so ago. I'm sure he'll weigh in here with his observations.
Great stuff. Finish is on a par with Campagnolo. Oh, and I use a pair of the alloy clamp/pivot bolts on the Colnago Mexico's NR seatpost. 8 years and still going strong...
