Always Full Tire / Bicycle Parts

Always Full Tire

Always Full Tires is an air-control system for bicycles that links the shock absorbers with the tires.
When a shock absorber pumps air, it is fed through a one-way air inlet valve and into the tire.
The system can effectively prolong your comfortable riding experience. What’s more, if can prevent you from worrying about whether the pressure in your tires is adequate.
