A new innovation for mountain bikes promises to make it much easier to get the optimal tyre pressure, allowing for the right grip and less rolling resistance.

Austrian manufacturer Tubolito says its new, smart and lightweight inner tube is the world's first that can determine the air pressure inside your tyres to a tenth of a bar and send it to a phone.
