SK Dobry den, mam kluky Shimano GRX RX600-1 (40T) ale rad by som vymenil pilu za 38zubov, pripadne 36. Je prosim tato pila kompatibilna? Bike mam Kellys soot 90. Dakujem velmi pekne.
Pozeram, ze uz to tu bolo riesene a vase 38T odporucanie je Wolf Tooth 110 BCD 4-Bolt prevodník pre Shimano GRX, 38T.
Viete mi prosim odporucit aj 36T riesenie (nech ma kazde zadne koleso o 10% mensi zaber nez pri 40T)?
Dakujem velmi pekne

SK Dobry den,

zial tento Ultegra prevodnik sediet nebude, GRX kluky disponuju atypickym kovanim otvorov pre skrutky prevodnika

Zial dostupnost prevodnikov je pre tento model naozaj zhorsena, aktualne len posledne 2ks 40T - https://www.mtbiker.sk/shop/komponenty/kluky-a-prevodniky/prevodniky/wolf-tooth-110-bcd-4-bolt-prevodnik-pre-shimano-grx-40t-p173887.html, 36T aj 38T u nasho dodavatela uplne nedostupne.

SK Pri 1x setupe odporucame urcite aj 1x prevodnik - ma inak profilovane zuby, ktore zabranuju padaniu retaze. Aktualne priamo pre GRX kluky dostupny vyborny 1x prevodnik od Wolf Tooth - v ponuke je aj 38T: https://www.mtbiker.sk/shop/komponenty/kluky-a-prevodniky/prevodniky/wolf-tooth-110-bcd-4-bolt-prevodnik-pre-shimano-grx-38-zubov.html.

GRX prevodniky vyuzivaju odlisny offset ako cestne modely Shimano, pri pouziti cestnych prevodnikov by tak bola pozmenena retazova linka.
