Let me preface this by saying I haven't logged thousands of miles with these yet and I'm not a "weight weenie" or professional rider. That being said, I've had absolutely no buyer's remorse. I did a lot of research on wheels before purchasing at Bonktown. For the 50% off price, they are a great value.
The positives: It's a lightweight carbon fiber wheel that isn't so deep that you'll get blown over with a strong Midwestern crosswind. Despite the relatively low spoke count, Reynold's does not have a weight limit on them (I'm 190+ lbs and my coworker who also bought a pair is 240-ish and we've had no problems). If you're like me, you've heard/read a lot about how high-end wheels greatly reduce squat and dampen road vibration -- it's absolutely true. They are touted as being durable enough to use as "everyday" wheels which is how I'm using them -- I'm not serious enough of a rider to spend a ton of money on a "race day only" wheelset. Lastly, you get the benefits of carbon fiber but can stick to the tire mount sytem (clinchers) you are accustomed to.
The drawbacks: I initially didn't like the white decals but they turned out to be great with my bike. While the weight isn't amazingly light, they are less than half of the stock wheels that came on my Madone. In terms of originality, they are factory and, in this respect, I would prefer to have custom wheels made by Ron Huff -- but yet not many people have these. Little things I didn't think about: you'll probably want to buy a new cassette if you're keeping your old wheels and tubes are more expensive due to the need for a longer valve stem.
Conclusion: If they're on Bonktown, it's a great way to get into the higher end wheel market without spending too much -- especially if you made an investment in a carbon fiber bike but are riding stock wheels.
