One of those that does know more is Yang Qi, who runs 27 Bike out of a warehouse tucked away at the end of an old lane. In fact, he's been known to help his friends at Specialized out in his spare time. Good news: his custom-built bikes are much cheaper than the corporate competition. Bad news: the warehouse is closed for renovation at the moment – a sign on the shutters directs all inquiries to the Specialized store just down the road.
