Introduced at Eurobike last year, we had all the technical specs, actual weights and details of the Schwalbe ProCore dual chamber tubeless system covered in detail. All that was needed was for it to start shipping, and today the wait is over.
Built around a tire within a tire concept, the ProCore setup places a thin, lightweight secondary “tire” inside your main mountain bike tire, allowing for a lower pressure where the rubber hits the trail and a higher pressure tube inside to protect against big hits. A clever valve stem and air guide let you inflate both with a single hole in the rim.
The parts will be sold as a complete kit and as individual parts. Ready to get pumped up…twice?
ProCore’s goal is to allow very, very low pressure for enhanced traction and small bump absorption without risking pinch flats or rim damage. The outer tire can be run as low as 0.8 bar (11.6psi), while the inner tube inside the inner tire is inflated to 4-6 bar (58 – 87psi).
The only caveats are the inside rim width should be at least 23mm and the outside tire should be 2.25″ wide or wider. Any brand rim and outer tire should work so long as you’re running tubeless rim tape (or a sealed rim bed) and sealant.
Parts include the inner tire, inner tube, air guide (red) and dual port valve stem (which is attached to the inner tube). Check our Eurobike coverage for an in-depth look at how it functions.
The complete kit will retail for €195 and include two bottles of sealant, rim tape, tire levers and Schwalbe’s easy-on tire bead lube with sponge applicator bottle…plus all the important parts of the system required to set up two wheels. If you’ve already got all the extras, you can buy the inner tube (€19,90), inner tire (€59,90) and Air Guide (€2,90) separately. It’s available for 26″ / 27.5″ /29″ wheel sizes.
We’ve reached out for USD$ pricing and will update as we get it.
