I've had this bike for about 15 years. The crack has been there for a long time, but I just started commuting regularly, and now after 3 months and 400 miles, the crack seems to be getting bigger.
It's an aluminum frame. I know I will have to get a new bike/frame at some point, but I am wondering how soon that has to be.
Is it likely or unlikely for this type of crack to fail catastrophically or will it just get slowly worse and worse? I know that know one can guarantee an answer one way or the other, and I know it's ultimately my risk, but I am interested in some experienced opinions taken just as that -- opinions.
Thanks in advance!
