My wife had a back injury but has recovered greatly to a point where she has started riding again. We went to set up her beloved litspeed catalyst and found the downtube has cracked. Can this be repaired? we attempted to make a warranty claim but it was denied of course. I did a quick internet search and this appears to be a common failure area for them. Hard to believe a 5'2" 120lb cyclist can break an aerospace material frame!
