We dream of a future where the grass is green, the dirt is tacky, and we never get flat tires. Thankfully, we're not the only ones, which is why the engineers at Cush Core have been putting their all into designing a tire insert that far surpasses yesteryear's attempted quick fixes, and even goes beyond to provide suspension of its own, inside of your tire, for a plusher, more supportive ride of the future. The Cush Core Tire Insert Set might be a dream come true for riders who have blown countless tires or cracked rims on rough rides, designed to mount inside of mountain bike tires to divide the inner volume in half, protecting your rim with dense foam that reduces vibration and adds lateral stability to your tire.
What makes the Cush Core so ideal is that it doesn't only take care of pinch-flats and protect your rim, but it actually improves the supple comfort of your ride by working as an inner-tire suspension system. This is achieved by filling half of your tire's volume with foam that dampens vibrations, while the remaining volume of your tire works as an air spring, effectively responding to blow and chatter like an extension of your bike's suspension, soaking up turbulent forces for a smoother ride. This reduces lateral vibrations by 77%, longitudinal vibrations by 58%, and even vertical impact by 50%. While, naturally, adding an insert to your tire will increase its weight, the Cush Core manages to reduce the rolling resistance of your wheel, so despite a bit of additional rotational weight, the added increased lateral stiffness works to keep your wheeling better than before.
The Cush Core Tire Insert Set comes along with its own valves, which Cush Core recommends swapping to when you add your inserts to your wheel, as they make adjusting air pressure and adding tire sealant easier than with a standard tubeless valve. Cush Core Inserts are easy to maintain once you've mounted them, but there is a bit of a learning curve to installing them, as they involve some stretching to get a tight fit on your rim, and moving an already difficult to seat the tire on top of extra volume poses its own challenge, so Cush Core recommends watching their installation video and playing close attention to instructions before jumping in head-first to your installation. Once you've taken the time to learn how the pros do it, it's only a matter of time before you can get your ride primed for with a flat-preventing cushion to ride every trail with confidence.
