Jelly Interlock Roller Skate Cushions Orange – boost your performance Unique to Chaya, the Jelly Interlock pink color cushions aka “bushings” is a special super high rebound PU formula. The interlock construction connects the coned and barreled cushions, saves more energy than non-interlock cushions and gives you a boost when you need it most. Jelly Interlock cushions absorb all kind of vibration caused by imperfect surfaces as well as impacts from landing jumps. No matter if you need more stability and control or increased agility, the selection of hardnesses of the Jelly cushions will do their job. The 12mm coned / 12mm barreled setup fits perfect to Chaya aluminum plates (e.g Shiva, Ophira and Zena). But, check if your own plate fits Jelly Interlock cushions as well to optimize your performance! The orange Jelly Interlock cushion is made in an 90A hardness.
