Is it safe to repair carbon parts? What's the general consensus? I'm aware that I'll invalidate the lifetime Cervelo warranty. But given that I cause the crack, the warranty is not valid anymore, so...
@drmutley: even if I caused the crack by falling? Basically the handlebars flipped and hit the top tube causing the zig zag crack shown in pic...Do you think they cover this? The top tube didn't hit any other/external object apart from the handlebars...

I know several guys(me included actually) who ride a CF frame that has been professionelly repaired, and with no problems what so ever. The frame only gains a few grams in weight, and the repair doesent look too good cosmetically - although in your case, it might not even be noticable if you can blend a new white top coat to the old one and cover the repair with paint.
I have personally ridden one of the mentioned repaired frames. No problems whatsoever.
I seem to remember that there's a company near St Albans who do this sort of repair as well (closer to you). Not sure if they have the experience to do it as well as some others though. Can't find them on a quick Google search though, sorry.
I did some research, and two companies seem to stand out:
1. Spyder Composites (USA)
2. Calfee (USA).
I'm based in London, I don't have a problem in paying £200 for a FedEx delivery (two way), but I need to be certain to get the best repair.
According to my research Spyder Composites came first. They even x-ray the frame and provide lifetime warranty on the craftmanship (!). And they are cheaper than Calfee too.
Any feedback from our American fellow cyclysts? Where is Spyder Composites actually based? (State)
1. Your crack not not appear to be particularly serious, in so far as cracks go. I would not even think twice about repairing it, and would be more than happy to ride it without a care once repaired.
2. I cannot speak for Spider/Calfee (which as you say, are rated as the best), but in my experience, HQ are very very good. I have only used them once, to repair a minor cracked chainstay AND a seriously cracked seatstay on the same frame. Their work was flawless. I went to the trouble of respraying the frame (using Atlantic Boulevarde, who are also outstanding), and now its as good as new - the frame does not look, or ride, any differently.
I would not bother sending it abroad if I was you. Get it sorted locally and you'll be fine. Good luck.
Re HQ Fibre Products, I agree with you, many good reviews, even from people I personally ride with. My concern is the x-ray, how do I know that the rest of the frame hasn't got hidden (not visible) cracks...? I like the x-ray service Spyder Products provide.
HQ Fibre Products can fix it for £68+VAT if I remember correctly. Atlantic Boulevard would respray it for around £290 (seems a bit steep?). I called Atlantic Boulevard and they told me that they sub contract the carbon repair to HQ Fibre Products...
Shipping: FedEx would cost me £100 each way I suppose. Atlantic Boulevard would organise the shipping for me for £48 return. Spyder Composites would fix it for around $160 incl. paint and respray. So, even if you factor in the shipping, the American shop is still cheaper...? Let's call it even, not a big difference I suppose.
Firstly, I know Calfee do good work (by reputation) but I don't know Spyder Composites. However, I would use either us (fibre-lyte) or HQ as you live in the UK. HQ have a good reputation amongst the time triallers in the UK, so they must be doing something right. Similarly, I think you'll find that all our customers have been happy with their repairs and we are the only ones I know of that add 'dimples' to a Zipp wheel repair
£290 seems steep for spraying the repair. Are they talking about a full respray or just for the repair? We have a local air brush artist who does our repairs and often can respray logos. He usually charges around £40-£50 depending on the work (he simply charges based on an hourly rate). For full resprays, Bob Jackson cycles in Leeds do full resprays for around £100
Not sure whether they meant to respray the entire frame for that amount...? Seems a lot of money for a tiny touch up. But I did send them the same pic. They said they would need to sand/work on the whole area between the Cervelo label and the black stipes.
Tonight I checked again the 'crack'. I took a better picture, please see attached. I tried really hard to bend/flex the 'broken' wall but nothing, it just doesn't move. It's exactly as the other side, the squaval downtube, the seat tube, all the same. Well, the top tube feels thinner and empty compared to the squaval downtube but that's because the downtube is beefy.
Looking at the picture, how do I know whether it's a structural crack or just something else? I can see something grey underneath the white paint, but doesn't look like carbon to me...there is a crack in the 'grey' thing. Will HQ Fibre x-ray it for me or do I have to call Cervelo Canada for this service...?
Please refer to first post for a different picture to put it into perspective. It's a 2cm zig-zag crack.
