Or a Harry Potter-esque scratch.
Right at the bottom of the seat tube where it joins the BB. Bit of a strange shape for a scratch though
There's a definite click if I run my fingernail over it :?

    Frame is aluminium.
    Here's a cleaned and cropped close up. There's a definite scuff between the two horizontal lines, but they are the ones I'm concerned about

    That is just a scratch.

    That is indeed...a crack...! but from your point of view...if in doubt...get it checked.

    thats a scratch man ! :)

    A crack on metal is usually kinda hairline and thunder-strike ish. Travelling down the welds or along the contact between weld and post in that case.

    How have you managed to scratch a frame so much in an area like that over such a short amount of time? Is it kept in a hedge full of brambles and barbed wire?
  • andy9964andy9964 Posts: 930
    @ mfin: I did manage a clipless moment a week or so after my first set of proper pedals, and that's the only thing I can think of that could've caused it.
    Funnily enough, I landed in some brambles on the left side, you don't happen to have half a dozen Springer pups do you (the reason I fell off)

    I don't want to start a new thread because there are a few of these. But what do you guys think of this?

    That looks like where the BB box has been joined to the chain stay in manufacture and just looks like poor resin impregnation. Is it smooth to touch? If not, the bike should not be ridden!

    If the bike was new, I would reject it because it should have been picked out by Quality Control and rejected or at least sent to be one of the models that has a painted finish (yes - gulp!!). Only the best carbon lay ups make it out for a naked carbon bike. This one isn't.

    Cosmetic carbon outer layers like this are very difficult to get perfect and provided you can't feel anything and can't open a crack up by pulling the axle points apart, it should be OK.

    What bike is it?

    It's a Felt AR4 2012. Luckily still under warranty for another year so I'm going to be sending some pictures to Wiggle.
  • lawrenceslawrences Posts: 1,011
    Knew it would be bloody Wiggle's fault :evil:

    I was contemplating putting generic bike retailer... wish I had. :)

    Is the frame creaking or is there anything to suspect it is a crack? Remove the wheel and flex the stays - a crack will move. Looks like poor finishing of the topweave - this is a cosmetic layer, not structural.
    Make mine an Italian, with Campagnolo on the side..

    The frame has creaked for a while. But it's a BB30 so who knows. I'll try flexing the stays later and get back to you. I should hear back from customer support today as well. Cheers.
  • lawrenceslawrences Posts: 1,011
    A mere month later and I've been told they need to collect the frame to assess damage.

    Baby steps.

    If you look on the right hand side, they layup also stops in the same place. To me- it looks like the end of the cloth and resin has spilt over .Doesn't look like a crack.
