I really really dont suggest going the adapter method. I picked one of these up a few months ago, along with a converter, and threw it all together on a fixed wheel. it worked great for a while, but over time the bb came loose, and the adapter didnt allow enough clearance for a proper wrenching. I took it off and threw in an american-sized BMX BB i grabbed for about 20 bucks somewhere on the internet, and it worked like a charm. great for a beater, because the thing really IS indestructible. No rack mounts make its utilitarian capabilities pretty limited, but its still a worth while buy, especially at less than marked price.
