I've not had good experience with Cervelo as a frameset or as a company.

I bought an R2.5, when it was delivered, it had a bubble in the drive side chain stay. I wasnt sure if it was in the clear coat (or whatever the outer layer is called) or the carbon fiber, had to send it back to cervelo for evaluation. Took them about 6 weeks to get back to the dealer I was working with and they concluded the frame was flawed. So they shipped another R2.5. It arrived a month later. I rode it twice and it broke while I was riding it, the non-drive side drop out pulled out of the frame mid-interval. Somehow I didnt crash.

Returned the broken frame to Cervelo, who in turn told me the issue would be resolved by sending me an R3 since the R2.5 was a junk PoS frame and being discontinued. This made me very happy, only it took them 3 months to get me the frame promised. So, we're talking nearly 6 months between my purchasing (and paying for) a new cervelo frame and one actually arriving. I have 3 team mates who were on R2.5s that were recalled and replaced with R3s. Now, cervelo has identified a design/installation error flaw in the steerer tube on the fork they spec'd for the R3 and have a recall on the forks. What a P-I-T-A.

I thought the R3 fit me kind of funky, I'm short legged and longer torsoed, and always felt a bit crunched up on the bike. Also, the spec'd fsa seat tube and clamp combined with the angle of the seat tube made it not possible to get a level saddle, which was annoyinng. I rode and raced the heck out of it for a season and a half, until the R3 broke this past May in a crash (not the fault of the frame).

Being frustrated with Cervelo from my prior dealings, and given that my team sponsor shop was no longer a dealer, I replaced the R3 with a Trek Madone 5.2. I was swapping components so only wanted a frame and fork. It took Trek 1 day to ship to the shop and I was on the bike a week after paying for it - as opposed to 6 months. The build weighs the same, and the Trek is every bit the bike the R3 was.

YMMV, but I'm definitely done with Cervelo. In my experience, good engineering/design, poor build and QC, poor customer service in the response time category, and according to the shop I work with, they were a nightmare to deal with (unreasonable volume demands, no lines of credit, unresponsive).
