    Frame damage opinions

    During a race weekend I busted a wheel which resulted in several miles ridden with my tire rubbing against my chain-stay and seat-stay (carbon) once per rotation. The photos attached show the damage which is a noticeable indent, looks like a full layer or two of carbon rubbed away (maybe .05 inches). Idk what the frame thickness is regarding what percentage is left intact but I’m hoping to get some opinions on how serious I should be about getting a new rear triangle.

      Yes. You’ve gone beyond the paint and have worn through the resin. You are able to see the layered carbon sheets.
      I would reach out to Kona and see if they would offer some kind of warranty.

      Personally, I’d just paint over it and keep riding. I’m currently riding a bike with similar damage and it’s been fine for over a year of very hard riding.

      Just to manage your expectations, I see this as more of a crash replacement issue. You may have to pony up for a new rear, hopefully at a good discount. I’m not familiar with Kona’s policies.

      Dish your wheel or find a different tire. The frame is ok. Just don’t make it worse.

      Before I saw it was a Kona, I guessed it was a Kona. Unfortunately this is rear triangle clearance seems to be an issue. Running a HeiHei and had similar damage, luckily I’m not carbon and just swapped out a smaller wheel but wasn’t impressed.

      It is not cracked and I doubt it will crack that area probably had at least 12 layers of carbon or more.

      It would be very easy to fill in the damage with replacement carbon and epoxy

      Kona won’t warranty that. You will be offered crash replacement, which is likely to be a couple hundred bucks.

      I’ve had this happen on a few frames and wouldn’t worry too much. I would put a coat of resin or something similar ontop of it to seal it and prevent water absorption.

      But no need to do a full warranty

      I’d get some automotive epoxy touch up paint and put a couple of coats on it. You should probably get it fixed or replaced though to give responsible advice.
