Pripadne nemate 30z prevodnik pro nahrazeni 32z prevodniku v tomto biku?

SK Dobrý deň,
boost verzia je určená pre šírku zadnej stavby 148 mm. Reťazová linka je dôležitá pre správne fungovanie radenia. Pre bicykel v linku budú vhodnejšie ne-boost kľuky.

SK Dobrý deň,

Boost a neboost majú rovnaký prevodník, rozdiel je v pravej kľuke s oskou (tá sa ale samostatne kúpiť nedá). Ak sú kľuky nové nejazdené a kupovali ste ich u nás tak výmena je možná do 30 dní od doručenia.
