the highest level of flat prevention and rim protection
CushCore prevents the tire from bottoming out against the rim in the event of a violent impact. This greatly reduces the risk of wheel damage and helps prevent pinch flats, tire "burping," and gashes in the tire casing.

No More tire "burp"
If a tubeless tire flexes excessively, it can eject air between the tire bead and the rim. This problem has been nicknamed "burping." Normally it occurs in a hard corner or a big impact, and is much more likely at low tire pressures. Burping happens because the tire bead is held against the rim only by the force of air pressure within the tire.
CushCore acts as a mechanical bead lock. It anchors the tire bead inside the rim so tire burping cannot occur.
