Here is a 10 speeds Raleigh Super Record I bought in Brooklyn for $40 (a high price for me), but I wanted to bring a little bit of Park Slope back home. I always intended to convert it into a single speed eventually. Well yesterday I popped the old 5 cogs freewheel, installed a 17 teeth single speed Shimano freewheel in its stead, and today I respaced the axle, redished the wheel, removed the derailleurs, and shortened the chain. A cheap but efficient job.
