Interesting experiences here re crashing and moving on.
I don't get emotional about bikes generally but after I broke my back I found that much of my trauma and healing were strongly connected to the bikes and riding. I kept the bike that broke me, (as well as the helmet that saved me) and for a while I couldn't even look at it without having a breakdown. I HAD to ride that bike again, it had become an important part of my healing. I sold that bike soon after, but painted my next one the very same colour, faced my trauma head on, had a few real tough rides and crashes, and am back to loving being on a mountain bike, just no big air.
I can see why one would want to ditch something that's so connected to a trauma, a la robatsu. I wonder if that would have been easier on me of if I would have taken longer to "let go". Hmmm.
OP: sounds like everyone's covered things, i would fix it if you're attached to it, buy a new to you bike if you're not. Keep the stuff off this one that you like and sell/trash/give away the rest.
