    Looking for input on cause of crack in carbon frame Pivot Les

    All,

    I have a pivot les frame and I have a crack near the bottom bracket. There may be a 2nd on the opposite side although I can't tell if it's a scratch or a crack. I didn't notice these until after I had a new press-fit bottom bracket installed at a local bike shop. After the work was completed The mechanic pointed out that it looked like a rock had cracked the frame and suggested I get it looked at by a carbon repair specialist. I didn't think of it at the time but when I brought it to the Frame repair shop he said it was more than likely due to the bottom bracket being pressed too tight. I'm just hoping to get your input and opinions before I ask the bike mechanic about it. The frame builder said it would have been apparent when it happened as it would have made a cracking noise. Also an oversized washer was placed on the crank arm and I'm not sure if that could have caused it as well. I believe it's more common to use a thin washer although I'm not a bike builder.

    Do shops carry insurance to cover these types of things? It's not a cheap frame and my only steed at the moment so I'm pretty bummed out.

    Thanks in advance.

    Certainly an odd place for a rock impact and it seems to be compressed and slightly folded at the most damaged spot. I am no expert, but I would also be sus about the BB installation

    I agree that those are strange places for a crack. I would suspect it was done by the shop who pressed in the BB. I always try to tell people to learn to work on their own bikes. A LBS mechanic will never take care of your bike the way you do. Besides, if he noticed those cracks, why didn't he tell you before he put in the BB. If we assume they were already there, he should have worried about making them worse or breaking the frame when pressing in the BB. So why didn't he tell you before?

    ooh, sorry to see this. With the cranks installed, it looks like it would be almost impossible for have a impact in that location. The shop will say they installed the bb properly and that should not of caused the crack. I think I would be inclined to take the position noted above, if there was a crack prior to installation of the bb, the mech should of seen it and alerted you to it. The shop will not have insurance to cover the costs of replacing your frame. They could go back to Pivot and ask them to replace as a manufacturer defect.

    I can feel your pain, I just cracked the bb on a 1 month old Norco carbon frame. stinks.
