I'm looking into touring in SE Asia later this year, and would like to get some opinions on frames. I've read a lot about people taking Al frames touring and being unable to repair them when they break. Is this a legitamate concern? I've had a 7005 Al mountain bike for 5 years which has been absolutely thrashed in the bush without anything breaking (except the rear deraileur), and don't really want to throw away money on a heavier CrMo frame. Do pannier racks put an unusual stress on the frame?
Has anyone ever broken a frame, and if so how did you do it?
