Can professional cycling reap the benefits of Formula One's hi-tech R&D?  We accompany world time-trial champion Bert Grabsch to Brawn GP's headquarters to find out. - By Daniel Friebe

For a journalist, there can be few things more titillating than being beckoned past a giant iron door and solemnly informed, "There are certain things in here that you're not supposed to see."  A security pass marked "Brawn GP" hangs from our necks and a minibus with blacked-out windows and large 'Highroad' stickers is parked to our left.  These are the only signs of what lurks within this anonymous grey sprawl of a Northamptonshire business park.

We're at Brawn GP's Brackley headquarters to watch Columbia-Highroad rider Bert Grabsch refine his technique and bike set-up in one of the F1 team's two wind tunnels.
