I'm no bike nerd but I recently bought two wheel sets from Tony at IRO. Tony's super cool and the customer service at IRO is great; so much so that when I ordered a 26 inch single speed rear wheel I got a complete set a few days later. I called Tony and told him about the mistake, he told me not to worry about sending the front wheel back. That's a free wheel! IRO uses their own hubs laced to Velocity wheels, you can get pretty much get anything Velocity has to offer. I know the Deep V's are real popular and so are the Aeroheads, IRO has both. The IRO hubs seem nice to me, they are smooth and seem to last quite a while. I haven't had any problems what so ever, even through those crappy Michigan seasons; that being said, if you need a new wheel set and don't have a million bucks to spend IRO has you covered.
