I've previously posted the fact that I find Cervelo's lack of replaceable headset bearing seats a sgnificant fault. The aluminum seats are so thin you'd be lucky to recut them once if damaged. Damaged headset bearing seats would be normal wear and tear, not covered by by warranty. As a mechanical engineer, I also think the lower bearing seat should have a full tubular inner suport. The inside of the headtube also reveals the sloppy hand layup and evidence of no bladder or other internal mold to insure high density and uniform thickness. The LOOK headtube is smooth and pecise inside and out.
Saying you are a mechanical engineer does not qualify you on bike design, unless you've designed bikes. You are taking about the support for the steel head bearings, most frames have these in aluminum, as they are not the wear point, the bearing is the wear point. The only way they can be damaged is by an incompetent mechanic.
As for layup, what you noted makes no difference to strength, EFBe testing has shown this.
The finish on all Cervelo carbon frames is far below that of LOOK and many other brands, for that matter. Put them side to side and compare. If you don't agree, then you don't know what you're looking for.
Too ridiculous a comment to respond to.
I'm not "shilling" LOOK. Although I like the brand, I like others too (like Colnago), but the Colnago geometry isn't my favorite for the mountain descents that I do on nearly every ride.
Why are you shilling Cervelo?
You attack any other frame manufacturer, other than what you have purchased, as some sign of advanced wisdom you need to share with the world. My only personal experience with Look is their pedals, which broke on me on the plastic cleat.
P.S. Engineer a spell checker.
