CS Dobry den,

optimalny tlak zalezi od mnohych premennych - sirky rafika, terenu (kvality cesty) v akom budete bicykel pouzivat a samozrejme od Vasich osobnych preferencii - pre zvyseny komfort je potrebne zvolit nizsie tlaky, pre rychlejsie odvalovanie je potom samozrejme idealne volit tlaky skor vyssie (podla specifikacie vyrobcu je mozne plast hustit po max. tlak 8.5 bar - jednotlive sarze sa vsak mohli trochu lisit, odporucame si rozsah tlakov skontrolovat priamo na plasti, byva uvedeny na bocnici).
