|Broken Bike Frame|
My mountain bike's frame cracked recently whilst I was riding it to work. It happened out of the blue so to speak - I hadn't jumped off a gutter or done anything else to give the bike a jolt.
My guess is that there was a latent defect in the frame, possibly caused by the weld nearby the crack. I would be interested to hear anyone's thoughts.
Here is a little more info on the bike to help with your opinions:
Here are a couple of photos:
