I second Peters thoughts. I had a pair with just over 4,000 miles (and I weighed anywhere between 250-270 the whole time. No problems. I just received a new pair from wheelbuilders,com -- I needed a new power tab. They did a great job on the build. Fast and reasonallby priced. The old wheels are still going strong and I intend to use them as spares. The old wheels are still going strong and I intend to use them as spares,
I have built many wheels with them. Great rim. Well made, flat, round when new..makes a great wheel.
