Carbon frame repair

by denver   May 10, 2014  

Hello all, on my ride out this morning in the Surrey downs I crashed. I'm ok but my bike is not. The derailer slapped clean off right where it connects to the drop outs. I've read load of conflicting advice on Google and I've spoken to several bike shops here in London. So what I'm asking is can anyone recommend someone who fix my frame in the London area. Also I would like to hear from any of you that have had experience of this type of repair.

Many thanks dee.

Stick up a picture or two of the damage.

Unless it is a track bike, it is rare for the drop out to be carbon. It should be an alloy of some sort, so unless it has twisted the rear triangle in any way. It should be a simple enough fix.

I was chatting to a chap in Swift Cycles in Spitalfields, and he told me about an unfortunate woman who'd forgotten to take the skewers out of her wheels when packing it into her bike box. Punched holes in the side of her down tube on her Dogma. Whoops.
Anyway, happy ending is that they've got a reliable repairer for carbon.

But as has been said, it seems more likely it's your hanger that's dead, which is a cheap and easy fix.

That really depends on the age of the bike. For carbon frames made in the last few years, manufacturers have largely moved to fully carbon dropouts. In fact, I'd argue its rare for dropouts to be metal on carbon frames these days.

I'd disagree with that, I have a couple of Treks, Madone 6.9SSL, a Speed concept and also a new Pinarello Dogma Think 2 and they all have alloy derailleur hangers.

There is no weight or stiffness loss, alloy allows the hangar to be bent back, and replaced in the OP's case.

I'd say the best thing is it take the bike into a shop, they'll tell you if the hangar can be replaced.

as giobox stated, most new high quality carbon frames actually have carbon drop outs.

as for carbon repairs, a lot of the work done is not guaranteed, however obviously if it goes again you can have it repaired again.

I personally wouldn't have any carbon repaired, id look at getting it replaced. Most bike brands will offer a crash replacement scheme if you are the original owner - might be worth a look.
