What can I do about a cracked frame? I noticed the other day that my frame has a crack in it! I believe that it's my seat post causing the problem. A couple of questions really, a) how serious is this? and b) can it be repaired?



Edit: I've added a picture of the height of the seat-post to give some extra context on whether or not the frame is too small for me. I've never thought that the seat was crazy high or anything; is it?
It's hard to tell from the photo ( is that large vertical streak said crack? ), but if your frame is cracked, don't use it. Riding on a cracked frame is risky as it could result in a catastrophic failure / injury / death.

It looks like that's probably a steel frame, so find a local frame builder ( not your buddy who's handy with a welder ), and depending on the damage they may be able to repair it for you.
