Then I saw the big crack and just gawped for a while. I guess it's a long-term fatigue thing that has resulted in catastrophic failure. Thank goodness for the lifetime frame warrantee.
You're so non-chalant about the whole affair. I would have freaked...

The bike is an aluminum frame. And they do have to temper them to get it strong; but when welded, they lose their temper and makes them weak. That is what I was reading about 6005? aluminum. It can be retempered in welded area so perhaps the frame builder didn't adequately retemper the area.

Anyway, I'm really glad you didn't get hurt. I hope you didn't ride like that back to your house or your car.
