I bought these wheels almost 9 months ago and they can truly take anything I can throw at them. I was slightly worried about if they would have to be re-trued or spokes would come un-tensioned since I'm a big aggressive rider. I weigh 220+ with all my gear and I take the fastest most brutal lines that most rims will not like, especially rims that only weigh as little as these do. I have put almost 1000 miles on them and they are still true and have been the best wheels I could hope for. My only gripe is that the stems that come with the wheels don't come with a removable valve stem. You can find them online for 10 bucks but it would have been nice for them to be included. It just makes it easier to fill the tire with sealant when the rim has been seated. You will not be sorry about dropping this kind of money because they look and perform amazing.
After 1 yr and many miles of abuse, the wheels are still sound with a bit of replacement parts. First thing needing replacement was a broken spoke from some unseen reason, only problem is they need to be bought directly from Easton. Which unfortunately means they only come in a custom bundle of 5 for 25 bucks, and 2 weeks of waiting.
Second thing was the rear free-hub that started grinding and crying out to be replaced. Once that was replaced the front wheel bearings started doing the same thing. They could have spared some of the bling on the hubs and put better bearings, but this is a common complaint on the 2009 wheels. I have read they use better bearings on the newer Havens fortunately.
There were things I didn't expect on rims at this price point and I hope are the last issues that come up.
