crabon fibre repair
Postby philip » Thu May 10, 2012 9:40 pm
I went , not what I wanted to see. I rode it home (10km or so) because why not, and had a good look at it. Crabon at that point is ridiculously thin - fingernail sort of thin!:
I didn't have warranty for this frame and I had heard some good things about a bloke name Stan at bike addiction in Manly. A few people highly recommended him. So I took it to him, he had a quick look and said it was a straightforward fix, picked it up today, extremely impressed:
He said he wrapped 8 layers of carbon around it (it's noticeably thicker but still looks great) and said it wont be breaking there again - it looks a lot stronger than it originally was anyway!
So - if you need any crabon stuff repaired in Sydney, I recommend Stan! AAAAA++ would fix again.

By the way, I was really impressed with the service I got from bike addiction. Their shop is excellent, they told me from the start the date it would be done by, didn't stuff me around at all, SMSd me to tell me the frame was ready to be picked up, I didn't have to follow it up or anything. Extremely good experience.

Wish I had known. I have a friend in the Auto Carbon trade. The problem with your man "apparently" is that he over strengthens the break. Making the parts on either side vulnerable. I am not saying this as a criticism, just a warning to keep and eye out on either side of the repair. I am also just passing this on direct from my friend, I can't validate it, just took it on face. Ironically, the guy he says is best is in.... Lane Cove. How about that

I am not however, so a personal comment on the repair is that it was a critical structural fracture/break so a cosmetic repair would not be enough as the complete sections are not being replaced hence the wrapping is the most effective and cost effective solution. There could be some merit in the point that other weak points could develop however this is difficult to resolve (and return to original frame characteristics) without incurring prohibitive costs of completely rebuilding the rear triangle or buying a new frame. By wrapping, I assume that the section has been completely wrapped around rather than repaired on one side.
A very clean looking repair if you ask me, and a relief I am sure that it is rideable again.

Mine probably wasn't as straight forward being at the drop out.

Interesting... I've spoken to a number of people who've had repairs done by him and none have had problems, except for one where it opened up in the same spot and he fixed it up again for free (as you'd expect). He told me that the places he joined it to were actually quite a bit thicker than the section he repaired, so hopefully I won't have that problem.ft_critical wrote:The problem with your man "apparently" is that he over strengthens the break.

I think most repairs are $400-500ish. Mine was $430.e466wa wrote:Were the repairs expensive? I've always been a bit concerned with damaging my carbon frame, almost to the point of downgrading to a metal frame.

Maybe they just pre-repaired it for you, knowing you were gonna wreck it anyway.

When I got back I had $4K to spend on a new bike. I bought back my wreck for $400 ( it was full DuraAce ) and bought my System6. Also I thought why not grab the bike I was using for a training bike... so when it fell to bits 6 months later I wasn't too worried.

To the guy who said something about over-strengthening: unless the repairs weakened the original carbon, the only "weak pint" would be how well the new carbon is bonded to the original carbon (assuming there is enough new carbon).

Care needs to be taken to avoid sudden changes in stiffness / hard spots -- the repair needs to taper into the good parts of the frame well, but having the middle of the repair 'too strong' isn't a problem in itself.
You can clearly see from the after pics that the repairer has done this.. there's no obvious beginning or end to the repair.
