I ordered a bike from my local performance shop and during assembly they noticed a small hairline scratch on the frame (beneath the seat).
They gave me a discount, and told me the frame still has the warranty and it was only cosmetic.
I have never had a carbon frame before and I just wanted to see if this could be something worse then cosmetic.

IMO frame material is irrelevant. It's probably fine, but damage is damage (or a defect) and that's what warranties are for. Why didn't your LBS notify the manufacturer and arrange to have the damage assessed? (rhetorical question)

Also, if it is only cosmetic, most warranties cover paint/decals for the first year (or less), so why not have it checked out now?.

You took possession of it? Ack... return, heck I wouldn't have paid them any cash for a defective new bike.

Clear coat on a new bike is thin and pretty flexible (not aged either)... if there's a crack in the CC chances are... take a guess. Was/is it really a crack?

This is the question I am asking...:confused:

I don't know if it is a crack, to me, it looks like a scratch in the paint.
They gave me $100 off a $1,100 bike for scratch that is about 2 inches long and that can not be seen from about 2 feet away. I would take 10% off for a minor scratch any day.

However, if a crack in carbon looks like a small hairline scratch, then I am concerned and will return to the shop.

They did offer to get a new frame, and that I would have to wait a couple weeks. Since they told me it was cosmetic, I took the $100.

Alright, seriously, if you're going to keep referring to this cosmetic blemish, post a picture. How is anyone supposed to give you advice whether this damage could be structural if there aren't at least some pictures? :)

I tried to take a picture but you could not see the scratch in the pic.
It looks like a razor blade sliced the clear coat, my finger nail barely catches it.

Cover the scratch with clear colour nail polish. Let it set in a dry atmosphere with low humidity for a day.

Don't worry abou it. It'll all blend into the background once you get riding seriously. As this firum member said...

Tell them to knock some $ of the price and go ride!

Let me tell you about 1,500 miles in late winter.

Ride the bike,....they gave you a discount for the scratch....quit worrying about it.....This fear of carbon is getting out of hand( not directed at you, this question comes up every couple days)...

If it will make you feel better, post I pic...

I agree with Dave and others - ride it. You will get more scratches in the CC and you can use clear nail enamel to fill them. You can also buff out some of the finer scratches just like on your car.

Something to keep in mind. I'm not pressing the panic button and neither should the OP, but CF bikes do suffer failures in different ways than steel, alu, ti. Most times, the latter will show cracks externally that are present internally. That's not always the case with CF, and documentation by several manufacturers states as much.

Chances are, the OP's bike is fine. We don't know the brand so we don't know the warranty terms, but chances are it's a one year deal on cosmetics (paint/ decals). If that's the case, why not have the bike checked out and go from there. No panic, just playing it safe and taking advantage of what the manufacturer offers.

Another observation. Since my membership here, I've seen countless threads having to do with what bike to buy, chain wear/ cassette wear/ numerous noises, saddles and on and on. IMO, so what. The forum is (in essence) a collection of cyclists that at one time or another either need help or assist others. That given, why is it an issue for someone to initiate a thread asking for member input on this particular issue. Given CF's unique characteristics, I think it's... warranted.

End of mini rant. :)

What could have assisted lionsandwings is a photo. I think this is what killed his attempts on reliable feedback. If I have an issue, I make certain to include photos or links in an attempt for the most complete feedback possible. When you read, "my fingernail can't feel it on the surface," the first thing that comes to mind would be a possible stress fracture underneath the clear coat shown as a refraction of lighting at the surface. How can we tell without eyewitness observation of some sort? Dayum, we don't even really know which tube it is on the bike [underneath the seat can be a top tube, seat stays, seat tube, joint adjoining seat tube and seat stays....]?

It's throwing darts in the dark.

Now PJ352, given that I got that off my chest, your efforts to clarify points on why we're all here are honorable. We shouldn't jump all over members who post questions and need help. If someone/anyone should have an issue with the thread ...they should avoid posting in it.:thumbsup:

By the way, having the bike looked at by another specialist cycle shop is perhaps the best advise given.

QUOTE]

Hard to imagine how a hairline scratch would look. If it's just a scratch, then you're alright. If it's a hairline crack, then use a quarter and tap the surrounding area to check for consistency in sound. Sometimes if there's a void in CF you can feel it by tapping. chances are you wouldn't find anything and chances are it's only comestic on the clearcoat.
