ZERO CUC is the solution for the rim in case of rips or tears. The CUC is the optimal protection to finish a competition or a training session. Introduced into the tyre, it protects the rim and allows you to keep riding. With an autonomy of 20km, tested in competition, you do not set foot on the ground, you continue to ride despite the loss of air. It is the CUC that will give a feeling of “pressure” to continue riding. The rim does not touch the ground, it is protected by the CUC.
