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 manufactured for PTN.
The Gravel Sport range is ultra-lightweight and features durable PTN inserts. The tyre insert has been especially developed from closed-cell technopolymer material to increase the functionality of Tubeless Ready systems. Furthermore, the driving precision is improved and the tyre is protected from impacts. In the runflat case, it is also possible to continue riding at moderate speed.
