OP I have a set of Velocity A23's laced to a set of Velocity Race hubs. The hub flanges on the rear hub are a high/low design. They are good hubs for the money--no complaints. Filings in the rims with less than stellar joints that cause pulsing, and a generally soft character to the rim keeps them out of the league of HED's and Pacenti's. They're certainly not bad rims, but at the price I'm seeing them over the past year, I'd go for the H Plus Son Archetypes. The "actual" weight is quite close to the A23, they are much stronger and have a really nice finish. The polished silver ones are just stunning. Match those up to some White Industries T11 in silver and the bling factor would enough to make most rappers start riding bikes.
