My only complaint was that I had Tony build me a wheelset and they arrived dangerously under-tensioned. Thus, I had to get the wheels re-trued. However, I can't really complain that much because Tony upgraded me to Suzue Pro Maxs for free (he was out of stock for the hubs I wanted). As far as weight goes, I haven't weighed it yet, but its probably about 18lbs complete.
