In addition to the MTB models, PTN now also has tire inserts for use on Gravel bikes in its range. The structure and the unique material of the Tire Noodle were specially developed for this purpose and exclusively produced for PTN.
Compared to the RokkLine and RaceLine tyre inserts, the R-Evolution version offers an increased level of sidewall stability. Furthermore, protection against burbing (tyre sidewall rollover) is provided.
Due to the intelligent design and an advanced choice of materials it was possible to achieve a very low weight, only 65 grams for size S (27.5 inch).
