A grandkid of one of my friends asked me to look at his bike, He said the sprocket wouldn't turn when he peddled. Ended up being the press welded post on the crank arm had snapped off. I had just purged all the cranks I had, so they had this laying around with blown out bearing and the peddles missing, so I swapped the crank out off it onto his bike. as I was leaving his grandma asked if I could use the rest of it and some other smaller girls bikes "which if I remember right I sold them a few years ago". those are getting stripped and I have this to decide what to do with. I do have the micro sprocket for it.
