SK zatiaľ po cca.500km funguje bez problémov, aj pocitovo sa točí ľahšie, bezúdržbové riešenie, prijateľná cena za kvalitu

HU A másik kérdés, hogy gyárilag az alsó görgő fogain van egy kis bemarás a grx 400-nál, de a BBB pont fordított elhelyezést ad meg. Maradjak a gyári beállításnál és alulra tegyem az ilyen kialakításút?
