Hi WW's.

I have an early Cervelo R3 (2010). It's happened twice - cracks around the bottom bracket drive side (BB does not seem to move under load). The first was replaced under warranty, now a new replacement is likely.

I've read a lot of topics on online forums about people experiencing the same issue. Most say the alu BB shell desintegrates from the frame, while a few claim it's just paint cracks due to flex, and there's nothing to worry about. Who should I believe...

Have any of you had such a frame where the BB shell really came loose? If my frame just has cosmetic faults, I'd be happy to just keep riding it, as replacements are a pain (rebuilding, old components don't fit, etc.).

There was only a small window of frames where they came unbonded. The white frames were only paint cracks. I believe it was the RS models that were most susceptible to the debonding. My 2006 R3 is still running fine, no issues.

There was a run of r3’s back in 2009 (give or take) which did have bottom bracket issues. But since this is the internet, I suspect it was a relatively small number that was magnified

I had a 2007 model that I rode hard for 7 years or so and never had any issues. Great bike. Well ahead of its time.

I owned the exact same model. bout two years later, I had it taken to a shop to be stripped to the fraeme, which I was going to re-paint, and the shop found a cracked bottom bracket. (As I recall that was a known issue at the time.) Cervelo sent a warranty replacement.

Cracks on the bb of Cervelos is a rather well known story.

Heard the same, also met a tour lead who was running a '10 R5 that had the same issue. All the cases I've heard (grand total of 2) Cervelo have replaced the frame without question. Suspect they had a small batch with issues.

However the old story, to be more precise.

I have a 2009 R3-SL that Im still riding and it hasnt cracked. The thread of the BB cable router corroded and I replaced it with a new Riv Nut. Apparently there were quite a few cracked BBs on these frames. Ironically Ive had two Colnagos that have cracked. Great frame except it only takes 23mm tyres.

I hope, in the case of Colnagos, it happened within two or three years from the purchase date.
This is the difference between brands like Colnago and Cervelo. With the first one you are on your own after their "generous" period they are commiting themself to look after you if something goes wrong. Not that much worry with Cervelo, at least where passing of time is a factor ;)

My R3SL cracked in head tube. Beautiful and dynamic frame, replaced without question under warranty.

Don't forget that if you are within their generous warranty period, they will take over 6 months to resolve the issue and half ass the paint job to fix it as well.

Today at Luescher Teknik's fb page:
"Found an area of what looks like uncured resin or similar foreign object in this @cervelocycles top tube. The area was easily found using an #ultrasoundscan
The next question is how did it get to be like that? Was it a prepreg fault or a foreign object during layup?"
