PROCORE - the outer chamber
The outer chamber is tubeless. Therefore, any tubeless compatible MTB tires can be used. The tire is filled with some liquid sealant (approx. 60 ml) and should be at least 57 mm (2.25“) wide.
PROCORE - the inner chamber
Two special Procore components form the inner high pressure chamber: the special Procore tube and the Procore inner tire. This "core" is extremely high pressure stable and at the same time very light.
Of course, the rim must be tubeless compatible and sealed with a tubeless rim band. It should have an inner rim width of at least 23 mm. The wider the rim, the easier the installation and the better the performance under low air pressure. The very wide Syntace rims are a perfect fit.
The PROCORE valve
The patented dual valve of the Procore tube distributes the air into both chambers. The upper part of the valve is a selector. With a simple turn, you select whether air is pumped into the inner or the outer chamber.
The PROCORE Air Guide
The small red component made of white plastic ensures that the air can flow past the inner high pressure chamber into the outer low pressure chamber.
