Schwalbe ProCore Mountain Bike Inner TubeOff road: Riding at lower pressure means better performance … but at the same time it increases the risk of failures. The limit so far is at about 20 psi, below which it’s hardly possible to dare to ride normal MTB tyres.But Nothing Stays the SameIn the future, air pressure can be controlled in the tyre’s double chambers. In the outer chamber, the air pressure is extremely low - ideal for maximum off road performance. In the inner chamber, directly on the rim, there is high air pressure - even a very strong impact cannot dent the rim edge. At the same time, the inner high-pressure system secures the tyre onto the rim. “Burping”, the dreaded loss of air at low pressure in conventional tubeless systems, is impossible.The NameProcore is derived from “Progressive Core”. The core (internal high-pressure chamber) progressively absorbs even the hardest impacts.CompatibilityYou can mount Procore with any tubeless compatible MTB tyre. The system is available for all three MTB wheel sizes (26", 27.5", 29"). Weight approx. 200g per wheel. Compatible with all wheels, independent of the brand. Minimum inner rim width: 23mm.Procore is a joint development of Schwalbe and Syntace.Procore - The Outer Chamber: The outer chamber is tubeless. Therefore, any tubeless compatible MTB tyres can be used. The tyre is filled with some liquid sealant (approx. 60ml) and should be at least 57mm (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 tyre. 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 23mm. 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 ValveThe 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. (Valve sold separately).The Procore Air GuideThe 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.Features: Use: MTB Type: Tyre liner Size: Multiple size options available to select Compatibility: Procore system Includes: Tyre liner onlyTechnologies: - Tyre pressure can be reduced to a minimum 14 psi, thus providing a huge amount of grip. Even on the roughest terrain tyres “stick” to the ground. - Due to the extra cushioning and traction there is much better steering, braking and traction control. - No more risk of snake bites. The rims are extremely well protected from denting. - Even in the toughest conditions, significantly lighter tyres can be used. - Excellent emergency running characteristics due to the internal high-pressure air chamber.Buy Schwalbe Wheels & Tyres from Chain Reaction Cycles, the World’s Largest Online Bike Store.
