Cervélo 2013 s2 frame crack
Rear brake bolt hole cracked. It's circular! What the hell is this? Have any of you seen this (pic below)? Was braking harder with the rear on a downhill cause there was debris and didn't want to lock the front. Them I heard and felt something odd. When I get home I see this. It's an actual crack, not paint. And it widens as you apply pressure to the brake....any thoughts?

Problem with the photo link. Please check and edit to correct.
BTW - I also tried to cut and paste in both Chrome and Firefox with no success.

I remember when I was in the market I was seriously considering the RS. Talked to a shop owner who said he got about 20 percent of them back with cracking issues. Sorry that you are having trouble.

I'd vote for paint damage.
Talk to your local bike shop to confirm

In that case, there is probably a sleeve that is loose, and you probably don't want to ride it until you get it repaired.

Looking at the ring which is uneven and not concentric to the bolt hole's axis, I suspect that the face isn't square. If so, the edge of the bolt or washer isn't uniformly supported and applying excess pressure in one area.
IMO, it's evidence of poor execution.
It can be fixed with some structural filler and spot faced, which should hold. A better solution would be a bonded bushing, with a cap at each end to take the bolt stress without damaging the carbon.
In your shoes, I'd open a dialog with the manufacturer and let him fix the problem, or replace the frame if he can't.

I'm chatting with Cervélo. I don't think there are execution issues here...everything always torqued to specs. Happened during a ride as well...

Having Cervelo handle this is the right way to go. If they don't make it right, have it repaired by a professional. It can be fixed, but it is not a simple repair.

Quick question here. You guys talk of a sleeve, but the whole are is made of carbon. I'm just totally stumped as to how this would happen when the bike wasn't touched in ages.

I can't speak for others, but my reference was to the idea of retro-fitting one. As it is, this frame doesn't appear to ever had one, though, IMO, a sleeve there is an element of good design, though not the only approach.
If the bridge is hollow, without adequate support against the compression of the brake bolt, that's poor design, plain and simple.

This repair is fairly easy to execute, but there are several steps. If Cervelo doesn't handle it, the frame can still be repaired.

I suspected that there was something, partly because it appears so in the photo, and partly because I tend to credit manufacturers with some brains.
However, it turns on the word "adequate". The way the area cracked implies that whatever support there exists is not adequate.
I agree that it's easily repairable with a retrofit of some kind, but that's Cervelo's responsibility.
IMO- they have a limited set of options
1- fix the frame (or pay someone to fix it) , and the OP should give them the opportunity.
2- replace the frame
3- refund the OP's money
4- deny it's a defect, and hope the OP gives in, and/or takes their chances with a third party arbiter in a dispute resolution process.

Wait...you have a crack in a carbon frame and it didn't asplode on you while riding downhill, sending carbon splinters into your body like bullets as you fly face first into the pavement?

Where are you located that you're forced to deal with Cervelo directly? Aren't warranty service issues generally delegated to authorized retailers (LBS) ? Try shooting an email to phil@cervelo.com
