Digital Valve Cap makes it easy

The Digital Valve Cap might be a concept, but it would surely come in handy should it ever enter production. This cap boasts a digital readout of the current tire pressure and relies on a small, built-in battery that is activated each time you press the cap, doing away with the need for a tire pressure gauge. Unfortunately, unless some sort of physical security system has been built into the Digital Valve Cap, expect these to disappear at a far faster rate compared to your standard valve caps on your mountain bike. Design credits go to John Wrightson for this.
