A low tyre pressure reduces rolling resistance off-road, increases traction and improves comfort. The disadvantage: With tyre pressures of 1.6 bar or less, the risk of punctures with air loss or even damage to the rim increases. In addition, tubeless tyres can move or buckle on the rim at low pressures, which also results in a loss of air.
Cooperation between Schwalbe and Syntace
In order to benefit from the advantages of low tyre pressure without having to put up with punctures, the two companies Schwalbe and Syntace initially worked independently on a solution - with very similar results: a two-chamber system makes it possible to run tyre pressures of around one bar without the risk of punctures, even during heavy use. Schwalbe and Syntace are now working together on a product to bring the system to market as quickly as possible.
Grip and puncture protection on a new level
BIKE was allowed to ride the prototypes with two valves per rim extensively in advance: With only 0.9 bar at the front and 1.1 bar at the rear, the grip level is outstanding. Hardly any slipping on loose surfaces in bends, perfect traction uphill and significantly more safety when braking. The tyres literally stick to the ground even in rocky, bumpy sections. Unevenness and stones are absorbed cleanly and the bike is noticeably smoother. The increase in traction and tyre suspension allows higher speeds and shortens braking distances.
The puncture protection is just as impressive as the riding experience. Neither the enduro race in Finale Ligure nor 15,000 metres downhill on La Palma elicited a hiss from the system. In principle, it can be used with all conventional tyre models, but the focus is on the gravity sector.
