A few days ago I was checking out the bike listings on Craigslist and came across this 1972 Raleigh Sports 3 speed. It is in rough shape. Today I started taking it apart to see what needs replacement. So far it needs new cables, brake pads, chain,  saddle, and tires. The tubes are still good. The chain was rusted solid and was difficult to remove. The cranks were frozen in place as well but I few sprays worth of PB Blaster loosened those up and they spin like new now.  The saddle is the original Brooks B72 but the leather is rock hard and torn. I’m not sure it is replaceable.
