I have a 1990 Raleigh USA technium competition. It has aluminum lugs bonded to reynolds 531 steel tubing. The seat post lug is cracked at the binder bolt. It still tightens snug but my father in law tightened it too snug when it was his. I was told it was not repairable.
My question is if the lug can be removed with heat and be replaced with a conventional braze-on steel lug? My aim is to transfer all of the components to another frame and convert this one to a fixed or singlespeed bike. Or should I keep the fork and toss this frame in the trash?
