I have Neuvations and OP's
Like yours, my OP's have lasted for about 6-7 years. They were my primary wheels for the first two years of their life, now the secondary set on my secondary bike. The Neuvations are great wheels - though I only have about 1000 miles on them. You can't beat the price, the weight, the performance or the service. Like the other poster said: low spoke count, super light weight wheels are not meant to last as long as 32 spoke, bombproof OP's. I figure that if I get 10-12,000 miles out of a super light weight wheelset, I'm doing well. I weigh in at 185-190 so I'm hard on wheels. For that reason, I just bought a pair of Campy Vento wheels from 11speed.com for $147 to use everyday. I will save the Neuvations for my long Sunday ride, the occasional competition, and my trip to the mountains of Colorado. When I bought my Neuvations the end of last summer, I compared them to every boutique wheel on the market. The reviews were so good and the price so low, I couldn't turn them down. Go for it...you won't be dissappointed. Call John Neugent and just talk to him a while. He'll tell you straight.
