PTN (Pepi´s Tire Noodle) was created to provide world cup runners with a high quality product that combines all the main characteristics that can significantly improve the performance of athletes engaged in the various DH-Enduro, XC disciplines and competitions where MTB All Mountain or E-Bikes are used. During the long period of design, research materials, ideal sections except for numerous tests on the test bench and in the field, the main objective was to create an ultra light component, but equally robust to ensure constant performance even during long Down Hill or Super descents Enduro. With its tubular shape and particular material, PTNs exert a constant, dynamic and progressive pressure against the lower internal walls of the tire and the lateral sides of the rim without excessively stressing the structural part of the aluminum or carbon rim. The use of the PTN allows the inflation of the tubeless tire without having to use a compressor. →PTN & PRO-M STORE← We at Pro-M Store, as an authorized distributor, have all the available PTN sizes: 27.5 ", 27.5" +, 29 "
