I purchased a set of Reynolds DV46C's with a PowerTap wireless 2.4 in March of 08. It's now 11/1/08 and the wheels are still running perfectly true after 6,000+ miles...no issues. My riding partner has the same wheels with the same miles and no issue with his either. If you want a bombproof FAST carbon wheelset that can be used daily, this is a great choice. The PowerTap has worked perfectly as well. I will definitely purchase any future wheels from Pro Wheel Builder. Richard was very helpful and provided great service.
