Today we present an insert for tubeless tires, studied and tested on enduro race fields, the Gummer.
The Gummer is a high-tech polymer structured multifunction system compatible with all types of tires, valves and latex.
In other words, it is an insert that adapts perfectly to the variations of soil that the rubber undergoes. It models based on the roughness following the slow or fast return of the tire.
As much as its appearance, it has three grooves and some holes that allow the passage of air and latex. There is also an increased hole near the valve to facilitate inflation and deflation.
