The original full-performance version. CushCore PRO allows you to push the limits of your tires and suspension to new levels. The best choice for the majority of wheels, terrain, and riders. PROTECTION TESTINGCushCore built a drop test tower to measure impact force. The test simulates a rock impact at speed. An accelerometer mounted on the carriage measures the deceleration rate when it impacts the tire (“G-force”). A violent impact delivers a sharp jolt to the rider and increases the danger of rim damage or a flat tire. CushCore reduced impact force by 50% compared to standard tubeless tire. SUSPENSION PERFORMANCE TESTINGMotion Instruments, a data acquisition testing specialist, used sensors to measure suspension travel usage with and without CushCore. More about testing methodology. The table shows the total suspension travel used during the test. Adding up all the compression strokes during 4-hours of testing, test bikes with CushCore used 15-16% less suspension travel. This shows that CushCore absorbed some of the bump forces before they affected the rest of the bike. CORNERING PERFORMANCE TESTSIn addition to Motion Instruments’ testing, CushCore conducted tests to evaluate cornering performance using an MTS Roehrig EMA-2K suspension dyno. Lateral Stiffness Test: The tire sidewalls are compressed equally from both sides. This measures sidewall stiffness. CushCore increased sidewall stiffness by 35%. Tire Roll Test: The rim is fixed in position while the actuator presses against one side of the tire and deflects it horizontally (see photo right). This mimics the forces exerted on the tire in aggressive cornering. CushCore reduced tire roll by 25%. VIBRATION TESTINGMotion Instruments, mounted accelerometers (“G-force” sensors) to two test bikes and ran a 15 mile course with CushCore and without CushCore. The accelerometer is mounted to the head tube, which can accurately measure bump forces as they are experienced by the rider. The test recorded cumulative G-forces (“shock & vibration”) — all the bumps added together during 4 hours of riding. Riders with CushCore experienced 11-12% reduction in shock and vibration. The riders felt a smoother ride and less fatigue. ROLLING RESISTANCE TESTINGWheel Energy, an independent tire and wheel testing contractor based in Finland, performed rolling resistance tests for CushCore. They apply a fixed load to simulate the rider’s weight and roll the wheel on a drum. The test compares a Schwalbe Nobby Nic 2.35 tubeless tire with and without CushCore at 25 psi. CushCore reduced rolling resistance by 3.2% compared to standard tubeless tires.
