By the by, even if the OP doesn't return with pics, not a useless thread. Lives saved

I would have thought the chain snapping would have resulted in the loose end of the chain flying very quickly through the chain guide of the front mech without any damage?

That's been my experience. Chain suck, on the other hand, can do all sorts of damage, including snapping the chainstay if you don't take the power off right away..

As far as the OP goes, if he genuinely has a beef with the shop and he paid by credit card, then he can put a claim in on his credit card.

Carbon frames are known for fragmenting into thousands of pieces if hit by a chain. Especially when it’s around freezing.

Indeed, and thank you. Also @Vantage and @Dogtrousers. This distinction is one which had hitherto eluded me . I do go back well before the birth of indexed gears.

It seems from the information given by you learned people that I'm using brake outers for both jobs.

I think it was indoors on a turbo.

Cold does not affect CF. It is used extensively in satellites, aircraft etc.

That's why they do the TDF in warmer weather then (I often wondered).

Didn't you see the film Gravity? Bits of smashed up carbon fibre flying all over the place.

You're not supposed to admit to that!
