Schwalbe has partnered with the component company Syntace to produce and design the Procore Dual-Chambered mountain bike tire system. This system consists of an outer main chamber that utilizes lower pressure (14+ psi) combined with an inner one that’s closer to the rim seat, which would use much higher pressure (55-85 psi). Offering better traction and control, a wider footprint, with no burping, pinch flatting and rim impacts.
