This is the company that is selling suckers a 10K frameset? Maybe they should figure out how to make their regular frames before building a halo one. On the plus side, they have so much experience replacing broken frames that they are very good and quick at it.

I have cracked four R-series frames in the last 24 months (all pre-2011 BBRight)...all cracked at the BB just like yours. If you visit the Cervelo forum you will see hundreds of others report the same issue with the R-series frames (all with cracks at BB).
Cervelo has never taken more then 10 days to issue a full frame/fork replacement with no questions asked. In fact they even upgraded my frame along the way. Their customer service is quite strong, unfortunately they have caused a lot of problems for those who have to keep paying a shop wrench to tear down and rebuild their bike. For me its not an issue because its the only time I really get to work on my bike.
Take it to your local Cervelo dealer, have them get the warranty replacement process started including sending pics immediately up to Toronto, then you need to follow-up with Cervelo directly and make sure they forwarded pics to Toronto and got the replacement approved. Shouldn't take more then a few days to get approved and then Cervelo will send out the replacement frame to the shop. In your case you will get a 2011 or 2012 with the new BBRight, which depending on what crank you are using, you may have to switch up (see BBRight compatible BB systems at bbright.net)
