I picked up a Raleigh Supercourse the other day in my dad's size, thinking I'll clean it up and give it to him to ride. I think it's a 72 based on the catalogs on retroraleigh.com but further reading there left me wondering something. In one place I read that the Supercourse was the least expensive model to use a normal threaded bottom bracket rather than the Raleigh specific one. In another place, I read that if a Raleigh has a cottered crank, it uses the Raleigh bottom bracket threading. I have a Supercourse with a cottered crank. Which of those previous statements applies in this case?
