I own a set and run them brakeless on my fixed gear. I like them a lot compared to the regular deep-v's or the wiennman wheels. Just make sure you get a presta valve longer than 53cm. Also, on my Tommaso that I run them on, the tires are very close to the frame and it almost seemed like they flexed a little when I took sharp corners and the tires rubbed a bit...other than that, they RULE. They look insane on a bike too. Scoop it up like ice cream!
