- Increased Control
- Most Durable Insert
PROTECTION TESTING
CushCore 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.
SECTION ONE _1.1
16% BETTER SUSPENSION PERFORMANCE
PLUSH RIDE
- CushCore absorbs bumps at the tire
- Less suspension travel used
- More travel available for big hits
MORE MOMENTUM
- More momentum on rough ground
- Better suspension without negative side-effects of a longer travel bike
“A 150mm travel bike feels like it has 173mm”
SUSPENSION PERFORMANCE TESTING
Motion 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.
SECTION TWO _2.0
CORNER HARDER
35% MORE SIDEWALL SUPPORT
CORNERING SUPPORT
- Faster Cornering
- More Traction
- Consistent Feel
- No Tire Roll
CORNERING PERFORMANCE TESTS
In 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%.
SECTION THREE _3.0
RIDE FASTER
12% MORE VIBRATION ABSORBED
FASTER ROLLING
- Smoother Ride
- More Control
- Less rider Fatigue
- Less Rolling Resistance
VIBRATION TESTING
Motion 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.
SECTION THREE _3.1
3% LESS ROLLING RESISTANCE
FAST ROLLING
- Reduced rolling resistance
- CushCore absorbs bumps at the tire preserving forward momentum
LOWER TIRE PRESSURE
- Improved floatation in sand and mud
- Freedom to run lightweight tires supple, fast-rolling casings without compromising lateral stability or impact protection
ROLLING RESISTANCE TESTING
Wheel 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.
SECTION FOUR _4.0
THREE STAGES OF TIRE SUSPENSION
SMALL TIRE DEFLECTIONS
Under normal load or “just rolling along”
- Little or no damping
- Lively Feel
- less rolling resistance than tubeless
MEDIUM TIRE DEFLECTIONS
Bumps and corners that flex the tire sidewalls
- Moderate damping
- interacts with tire sidewalls
- Supports tire sidewalls (stable/less tire roll)
- Controlled rebound (less bounce and deflection)
- Less Vibration
LARGE TIRE DEFLECTIONS
Impacts that fully collapse the tire
- High level of damping
- Dissipates the impact energy
- Reduces bump force experienced by the rider
- Damps rebound force, helping tire to remain in contact with the ground
- Protects the rim and helps prevent flats
TOTAL
CONFIDENCE
THOMAS VANDERHAM
“I like the fact that the insert holds the bead and helps reduce burping under extreme cornering conditions.”
