    Carbon frame damage opinion

    Hello,

    Looking for some advice regarding a bit of damage to the carbon frame on my Propain Tyee and the carbon Zelvy rim. The frame is raw carbon, the damage is on the back of the seat tube, half way down. Itís a small gouge that exposes the fibres. The damage on the rim is only shallow and I canít see any fibres.

    Iíve just bought the bike unseen, the damage wasnít visible in the photos but it was described as very good condition and only used for 2 months.

    Is this damage worth worrying about?

    Thanks,

    James

    I take back what I said about rim OK, it could easily be flared/split/delaminated internally

    risky

    I don't like seeing straight line damage (crack/fracture) with carbon fiber stuff. It's usually an indicator of a pending fracture or failure point. Is there an indentation on the seat tube? If there's no impact damage, you might want to check with the frame manufacturer to see if it's covered under warranty. You never know.

    Shame on the seller for not disclosing that.

    Yes thereís a designed indentation in the tube but no impact damage. It looks like a big rock has got jammed up there somehow Iím guessing.

    I would send that right back to the seller. Very good condition? I don't think so.

    My sentiments exactly... The seller was not upfront in disclosing the damage. If he's a standup person, he will either offer a discount or refund.

    Yes I agree but it would need to be a big discount, Argos charge c.£450 to refinish a carbon frame let alone repair one.

    They lied to you to get your money. If you have any transaction insurance I'd start a claim.

    Iíve opened a case now and received a (quite patronising) response from the seller suggesting Iím expecting too much from a bike with 2 months use and the frame damage is not significant. The bike also has play in the suspension bearings, a very rough headset and a rear tire full of cuts with sealant pouring out the holes! Apparently I was expecting too much from ďvery good conditionĒ. On further investigation, he sells loads of bikes on pinkbike, not great business sense! He has offered to replace the tyre (with a crap rock razor) and replace the rim but what use is that with a damaged frame?!

    That's useless. Do whatever you can to get your money back and give him back that junk.

    I'll just chime in to agree on gettin uyour money back asap, that's BS. I'd go a step further and call him out here and Pinkbike to spare others the same fate. Guys like this don't deserve a platform to sell stuff within the biking community.

    Iíve shown Argos the damage and the frame does need a repair, not to mention the other issues. The seller has at last, reluctantly, agreed to take the bike back. I am very tempted to name and shame on here as heís been extremely difficult to deal with but I will give him a chance to do the right thing and refund me in full before I go any further.

    *fingers crossed* you get your money back. Get the $$ then you can deal with him publicly. Just giving your money back doesn't change the fact he is being a douche bag and will probably put that bike back up for sale as mint next week.

    Ahh yes, the ol "I pin-balled the frame off a cliff and through a rock garden but it's like new, only ridden 2 months" shtick. I assume everyone selling a bike is a scammer until proven otherwise.

    I would call him out publicly because if he did this to you, I'm sure he has done this before or will do it again.

    Damage doesn't look too bad to me.
    Superglue and baking soda and sand it back is a quick repair you can do for small damage.
