Hi everyone

I was wondering if someone could talk about how to asses you bike after a crash. I had a crash back in september on my bike. Being the concerned bike parent I am I took the bike to my LBS... (don't like the shop... love the mechanic) He checked the alignment and what not and he gave it his once over trued my wheels etc.

My concern is the there is a noticable dent in the top tube and a smaller one in the down tube. The bike is a pre trek thick aluminum tubed Klein. (super thin walls) and I am concerned about the future viability / safety of the bike... what can I do / look for to avoid catastrophic destruction of my beloved bike while I'm on it

Do these guidelines apply for all types of bikes (aluminum, steel, ti, carbon) what capacity exists for repairing bikes (for those of us who have not yet won the lottery and can't really afford a new bike)

thanks ahead of time
