Electronic gear shifts are gradually finding their way from Formula One into high-end road cars, but bicycles have beaten them to it. The system pictured is from French manufacturers Mavic. Shifting up and down through nine gears is controlled by the two yellow buttons integrated with the brake lever, the two on the lever mount top or those on the computer. Connection between the three units is through a CE-approved sub-150kHz radio link, waterproofing is to IP67 and battery life on all the units is over two years,claims the company. Mavic is not the only firm involved in electronic gear changes. Browning, the machine gun makers, made one a few years ago and Shimano has speed-sensing four-gear fully-automatic model with normal, sport and manual settings.
