A bike sits aboard the balance at the Specialized bike-specific wind tunnel just unveiled.

The tunnel has a large test section.

This is a linear "open circuit" tunnel that sits inside a large, vaulted warehouse a quarter-mile from the Specialized headquarters.

This is not just a tool to make better products. It's a process play. Sit retailers here, ask them to watch, and then subliminally ask them how Trek and Giant can match this.

Behind the curtain: It's a linear tunnel in a big warehouse. But it's breezy in that warehouse, so, no shipping done out of here.

Rather than one large fan, hard to replace or fix quickly when down or broken, Specialized opted for six smaller commercially available fans to power the tunnel.

With an open circuit tunnel you must work harder to smooth, condition and straighten the air.
