There are no false promises, just a solid product backed up by heaps of testing and data- lots and lots of data. As the years have passed the race results have started to add up and so has the number of riders using it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWho's this item for:\u003c\/strong\u003e Trail, Enduro, All Mountain, E-Biker, DH racers and riders alike.

The spring would support the load while the damper would dissipate the energy. CushCore's 'Inner Tyre Suspension System' delivers this technology to tyres for the first time. The engineered foam insert mounts inside a mountain bike tyre and divides the inner volume of the tyre in half. The air underneath the tread patch and the CushCore insert next to the rim. Together they work as a spring and damper. The air is the spring, the insert is the damper.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDurability:\u003c\/strong\u003e Cushcore inserts are extremely durable. One of the early tests to determine how well the foam would 'rebound' back into shape was to repeatedly strike it with a hammer on a concrete floor. Agricultural yes, but it served the task. The foam is engineered to repeatedly withstand poundings without degradation. A set typically lasts a few years, although the service life depends on riding frequency, terrain, tyre pressure, and other factors.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFitment difficulty 1 - 10 (10 being the most difficult):\u003c\/strong\u003e This is the most commonly asked question about tyre inserts. How many gorillas am I going to have to befriend to get these things installed? If you have never installed CushCore and prefer to work things out yourself rather than read instructions- all of the gorillas. If you don't mind taking 5 minutes to read the instructions or watch the installation video it's not too bad. You will run into difficulties if you don't use CushCore's installation method. Fitment difficulty = 7\/10 Oh, a garbage bin will be a huge help too.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStand out Features:\u003c\/strong\u003e This is currently the only tyre insert on the market that offers rim protection as well as a tyre suspension system.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlush\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMotion Instruments, a data acquisition testing specialist, mounted accelerometers (“G-force” sensors) to two test bikes and ran a course with CushCore and without CushCore.
