Is this damaged aluminium frame unsafe to use? Hello
I have a Giant Seek 3 aluminium frame where somehow the rear rim has rubbed the frame creating a hole as shown in the picture. On the other side there has also been some rubbing/scratching but it hasn't created a hole like this side.
I suspect it's unuseable/unsafe but just would like to confirm if anyone knows.



Update: Thanks all for your help.

I have decided to just salvage the parts off it and throw away the frame.
If that's a chainstay/seatstay, then it really is unsafe.

With regards to @DavidRicherby and @ChrisH 's comments, I agree that you should go consult your LBS or any local frame builder. If you're lucky enough, it might just be salvaged by bridging/filling that hole by welding.

If you do plan to ride it in rough areas then I personally suggest you get a new bike frame instead. Fixed or not, the chain/seatstay is already probably compromised enough that I'd get off and lift that bike up every time I encounter a pothole or speed bump.
