Summary: These Zipp rims (440 tubular) are very light and fast-accelerating. However, they are highly underengineered. I used them for about 15 cyclocross races (no training on them at all) and they broke. I'm talking 30 cracks around the rim broken. I sent them in to see what Zipp would do about it, and they told me that I was out of luck. They said they were designed "to crack when impacted hard enough to deform the bead of an aluminum rim". That means that if you hit a rock, branch, twig, beatle with them they're designed to break. Who hasn't gotten a ding in an aluminum rim? These are a complete waste of money unless you plan to ride them on an indoor trainer, or if you get them for free. Strengths: Fast acceleration, light, they look cool. Weaknesses: They break if you look at them wrong. I weigh 175 lbs, and they're absolutely unrideable after 1 year. They begin by cracking through the braking surface, then the pads catch the carbon and rip them to shreds. No longer even rideable. A waste of my money. Poor braking when wet as well.
