Bottom bracket help!

Do you still ride this one? http://www.londonfgss.com/post238651-94.html

I hate to tell you, but I think you got ripped off. It's made from air, FFS. What were you thinking?

I mean, air is really light, and is a nice ride but I've heard that air cranks often have your problem.

Yes that's the one, the man in the shop said it was the lightest bike you can get (that's why it cost so much) - he also sold me some magic beans and 2 year pass to all the London parks.
