Schwalbe’s new Dual Chamber System, PROCORE, is getting closer to public release. The system is being tested on the Enduro World Series circuit with Nico Lau and on World Cup DH circuit with Emmeline Ragot and Sam Hill.
PROCORE is short for progressive core. The “core” is filled with a high pressure of about 55-85 psi and progressively cushions very hard knocks. Therefore, the outer tire can be ridden at an extremely low pressure, which reportedly leads to improved tire performance. Running a standard tube pressure of less than 20 psi runs the risk of possible snake-bites.
The potential opportunities are positive
– Reducing the tire pressure to 14 psi will provide huge amount of grip, even on the roughest terrain.
– The lower pressure will improve cushioning.
– Due to the extra cushioning and traction, there will be better steering, braking and traction control.
– Reduced risk of snake bites. The rims will also be better protected from denting.
– PROCORE’s inner system secures the tire to the rim and prevents the dreaded “burping” of tubeless tires.
PROCORE system is a joint development with Syntace, but it can be mounted in all conventional wheels that have a minimum internal width of 23 millimeters. Weight per wheel is 200 grams and will be available in all three mountain bike wheel diameters.
Following Eurobike, Bike will have more information on PROCORE.
