Welding on Big box store bikes?
So I took a used hub in to get it laced onto my Cranbrook rim so I can add disc brakes to the MB. The guy at the shop say welding to a bike is like welding to a spring. How true is that on the cheep bikes like Cranbrook? I am a good welder and have no doubts about my skills, but will I do more harm than good metaurgecly speaking?
