Hey CLTracer, what you say is true - no one has lost a race because of it but it seems like several people I know have complained not only of the chainring but of the front derailleur being flexy and not shifting crisply. I know a couple of guys using DA fr der to make up for it, along with DA cassette.
Hey Toonraid, I can see why you are suspicious of iridepinarello's review. It comes across more as an advertisement to buy it than as an objective review. I can provide a slightly different perspective, owning all the bikes in the Pinarello race lineup except the FM1. The Prince Carbon is a lighter, more brittle version of the Dogma 60.1. It is lighter than the Dogma 60.1 (because Dogma's new aero seatpost and fork are heavier, as well as the additional reinforcement Pinarello has put into the carbon weave, which they call nano-somethingorother). I have never had bad luck with my Prince but I have 2 friends whose Prince frames have cracked and were covered by warranty luckily. In fact, one of them paid the difference for the Dogma 60.1. The Prince feels a lot harsher than the new Dogma, partly because of the nano-stuff in the carbon, and partly because Pinarello has strangely made the Dogma 60.1 more VERTICALLY compliant, while laterally stiffer. It is a very strange feeling -- I'll explain what I mean -- it's not good.
When I first climbed on the carbon Doggie, I thought it was sweet because the first thing you'll notice is how smooth it is. Usually, I would argue that a Colnago C50 is one of the smoothest riding bikes made, but the Doggie makes the C50 feel almost harsh by comparison. But my impression went quickly from positive to negative on the first steep climb on the Dogma, because I actually felt a "bouncy" sensation. I guarantee you it was the frame. Here's my build - you'll see nothing on it is flexy:
However, the frame felt like it was flexing vertically right down the middle of the bottom bracket. I notice it on very steep inclines where I'm out of the saddle in a small gear (34x23 - since I have compact with 11-25 on this one). It's not a characteristic I like. On the other hand, I never felt that on my Prince.
.
So I feel Pinarello decided to "market" its way out of the Prince's defect issues and make the Dogma more reliable, slightly heavier (exact same build with LW standard wheels -- yielded about a half pound difference in weight), and smoother, but built in some vertical compliance to achieve the smoothness. In fact, it feels more like the Paris. It would be interesting to see how both bikes (Doggie and Prince) would fare in a more scientific machine-based flex test. Although I would be willing to bet the Prince breaks first....
I also always prefer to feel the road more, as long as it is not a bone-chattering aluminum-inspired harshness. iridepinarello referred to Porsches in his review so I'll use the same analogy -- I'm not sure I would liken the Dogma to a 997 Turbo -- it felt more like a Mercedes (or dare I say Lexus given how much it deadens the road) than a Porsche. The Prince on the other hand, feels more like a Porsche (or even a Lotus given its harshness). I would therefore even argue the Prince is actually faster in most race situations given its weight advantage and stiffness.
Disclaimer: I got rid of my Prince frame, and plan to get rid of my Dogma after next year. The one frame I would NEVER sell however (and I have collected several since they are no longer made), is the magnesium Dogma FPX (not the first gen with the proprietary BB but the latest rev before extinction). This I think is the best kept secret and was unfortunately (or fortunately for some) a marketing failure with the masses going for carbon. I would liken this in the Porsche analogy to the naturally aspirated masterpiece 997 GT3RS. It has the most incredible ride. Only drawback is that it's really a fairweather bike given the properties of magnesium, but you put it on a stationary trainer and you can actually prove to yourself that this bike is much stiffer in the bottom bracket than both the carbon Dogma and the Prince, despite what any bike shop markets. If you ask Fausto Pinarello, which bike is the best they have ever made, and he will tell you personally that it's the magnesium Dogma: (sorry, cell phone photo)
Hope that helps as a credible review. If you're considering getting the Dogma 60.1, I would save the money and buy yourself a set of Boras with a Prince instead.
