Beach cruiser question...1 piece crank help.....?

Question

ok, i feel like an idiot asking this, but here it goes...i just bought a gt dyno kustom kruiser roadster(stretch cruiser)....it has a 1 piece crank and i want to change it..where can i find 1 piece cranks on the internet? i see alot of sprockets, but as far as i know, those would be for a 3 piece crank...i may be wrong, little knowledge on the subject, sorry. anyways, is a one piece crank mean that truely the crank and sprocket are one? and also where can i find online the kind that im looking for....thanks guys, 10 points for the best help!!

Answer 1

No, a one piece crank means only that the crank is one piece of metal. The sprocket is another, attached to it with a peg. I don't know where you would get another one, because I live in Britain and have only heard of one piece cranks on American websites, but you should be able to find one.

This article should explain it better.

Edit: I found a link on the site that sells the item you require. http://sheldonbrown.com/harris/opc.html#...

Answer 2

The style crank you want is called an "ashtabula" crank. As with most things bicycle-related, Sheldon Brown's (RIP) site has an article describing ashtabula cranks.
