Disclaimer: I don't have a micrometer.
So I bought a k2 arapahoe 20'' childrens mountain bike today. Tires held hair so I was riding it around the store, and it seemed mechanically sound, so I bought it. 10 dollars spent at salvation army.
I want to make it ridable for my self. The quill stem appears to be bigger then 1''. What size could it be? (how many different possibilities.) Also, aany body take a wild guess on the seat post size?
Also: What would you guess the rear spacing to be? (Its has a 7 speed freewheel)
I don't have measuring tools.
Has any one ever heard of doing this? Links?
