"The lightweight wheels compose of carbon rims and advanced hubs, in which a miniature high-pressure pump is stored, which is driven by the rotation of your wheels. Via an integrated clutch unit and electro-pneumatic control system the pump gets only active on demand. The wheels are fully compatible with standard bikes. You manage your tyre pressure wireless from your handlebars. Meanwhile, all relevant information can be displayed on your bike computer."
Zelf vind ik het onnodig, maar wie graag geld over heeft voor nieuwe technische snufjes is het misschien wel een aardige upgrade voor de fiets.
