Hi,
A friend brought me his nuke proof mega, he had lost the horst link bolt and wanted it replace. He rode the bike for a fair while before realising it was gone.
It appears this has allowed the rear wheel to wabble and abraid the lower chain stay.
Is this too much abraision, will it be ok or should he get it repaid, its a little over a year old.
Thanks
Rob

I had a similar cut into the aluminum rear triangle of my Kona Hei Hei. It eventually failed but luckily not at a dangerous time riding. Kona replaced it under warranty even though it was originally bought by someone else in another state.
It is abrasion to the point that regular sideways loading like in turns will eventually lead to a failure on this new weakpoint. Not the next few rides perhaps. But I would not risk it. Too many cut fiber strands
I would start looking into getting a new chainstay
Personally I’d keep riding this. My bike has various nicks and cuts on the frame, including an alarmingly large delamination on the bottom bracket area, and I’ve been riding this bike relatively hard for the past 3 years with no creaking or failure. Mind you, I also buy weird carbon parts from Aliexpress and generally have little concern for my long-term health compared to some more mindful riders. I also weigh 60kg, so about half the weight limit for most bikes.
Do stupid shit at your own risk, the smart thing to do is to get a replacement chainstay.
There’s about 8 or 9 distinct layers I can see gone. That’s an accident waiting to happen
Rock it till the wheels fall off
That’s gonna break, the carbon layup is clearly compromised. Take it to a repair shop.
it’s repairable and needs to be repaired.
