SK Dobrý deň,

Podľa BCD áno ale tvar ramien uchytenia prevodníka je rozdielný (viď. https://images.mtbiker.sk/eshop/big/140793-shimano-grx-fc-rx600-10-11-30-z-10-11-sp-prevodnik-69dc3a00eacf134797eb8a30c3763551.jpeg) a kompatibilitu preto nevieme potvrdiť. Ak by ste mali záujem o 30 zubový prevodník priamo z kľuky FC-RX600 tak dajte vedieť a preveríme dostupnosť.
