Use one of these. http://www.treefortbikes.com/product/333222361058/481/TruVativ-American-to-Euro.html

And MAKE SURE YOU PUT IT IN THE RIGHT DIRECTION!!!!

Bottom Bracket threads are different from one side to the other of course. I'm not sure if the adapter is marked drive side and non-drive side, so check it out with your bottom bracket parts before installing it. They work pretty well.

You have that option or buy a 3 piece American Bottom Bracket.

Look for "3 piece American Bottom Bracket" and you should find something.

Here's one example.

What he said (above.)

You can also find them on used 80's-90's cruisers. I've bought diamond back "sandstreaks" for $100 or less just for the parts.

They have 26" Araya alloys with stainless spokes, three piece cranks with the American bb, and some other parts I've used on custom bikes.

The american 3 piece bb was popular in the 80's for BMX, and they're easy to find.
