Carbon Damage?

petehk22

First post ... be gentle

Have decided to go full carbon and bought the Specialized Tarmac Comp.

I been merrily sorting gear indexing on my turbo trainer and the bike has slipped out of the rear mount (with me on it).

Having heard the scare stories about damaged carbon I was initially pretty concerned but looking more closely it has scraped off paintwork about 1mm deep a centimetre or so up from the wheel mounting and exposed a silver surface.

Question is, is the wheel mount section actually aluminium or similar and goes in to a carbon tube a little further up (in which case I'm lucky) or have I done some damage?

Will put pictures up if I can work out how to ...

Looks all the world like aluminium to me

Aluminum - same as on the drop out just below.

Looks like Alloy but its also a long way up from the clamping area to still be alloy.

however, does your turbo need a specific QR ? mounted properly, bikes dont come out of a turbo by them selves! u dont want it happening again!

Yes Alloy, and don't use a quick release like that in a turbo, that's why you fell out.

Need one with a ball end like this.

Thanks for the comments. Intended to use the old aluminium frame bike on the turbo but will probably get one of the suggested quick releases as suggested. Will also get a bike maintenance stand so I can index more easily in the future. :shock:

that is the alloy drop out, so no carbon damage.

if you don't have a correct skewer try doing the clamp up so it points horizontally, that way there is no rounded edge for it to pop out.
