Polo Bikes

There's a Hong Kong seller on ebay who is willing to mark down the item when posting and for that same amount IIRC you get a pair. Not too sure BB5 or BB7 though...

BB7 is £55 on Chain Reaction, and the BB5's are out of stock, as they seem to be with a good few places.

Not cheap, but I might pick one up anyway.
Louis if you're interested in the short pull road BB7's let me know.
