I've got a bucket full of one piece cranks and another bucket for stems... none of the bikes on the trailer had anything I didn't already have multiple of. There were some straight wheels on there, but all the coasters were 20" junk. Some BMX freewheels, also junky though. Not a single good seat on the trailer. There was 1 good tube in a 20" tire, but the valve core would not release the air or come out, so I left it... it bounced when I threw it off the trailer at the scrap yard.I am forever hounding for scrap bikes for coaster rear wheels and one piece cranks.(also I strip for stems etc)..You just scrap them..
