Low pressure tires have more traction. This is one of the underlying reasons that mountain bikers have flocked to tubeless tires and wide rims.

Both of these technologies enables riders to let out a few PSI, rip corners, and climb better, but they come at a cost. The one mentioned by tire manufacturer Schwalbe is snake bite, but we’d like to also include the greater risk of developing a flat spot, and burping when cornering aggressively.

In order to reduce the risk of these scenarios, the company has been hard at work developing a dual chamber system they now call Procore. We’ve gone over the basics before, but essentially, the new system utilizes a inner tube (that’s not really an inner tube) to inflate the center channel of the tire. Then a second valve is inflated at a much higher volume, which presses against the tire bead. This helps prevent burping and allows the rider to dial in traction without worrying about flatting.

The entire system is expected to weigh 200g and be compatible with existing tires. Full press release and more pictures below:

No more snake-bite punctures: A revolutionary dual chamber system makes it possible to ride with very low air pressures and, as a result, improve tire performance enormously. Initially, Schwalbe and the wheel manufacturer Syntace were working on such a system independently of each other. Now, the two companies have joined forces to further develop the dual chamber system.
