In rough terrain the rule is: if you ride with lower air pressures, the performance always improves ... but at the same time the risk of impact punctures increases. The limit value is currently around 1.5 bar, below which the risk of snakebites is simply too great.
But nothing stays the same: With the PROCORE system you can lower the air pressure down to 0.8 bar. The secret lies in the double chamber system. While you lower the pressure in the tyre - of the outer chamber - the inner chamber, composed of the PROCORE inner tube and the PROCORE tyre, protects your rim with a high pressure.
- 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.
- The rim: 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.
