Variant Shimano GRX RD-RX810 prehadzovačka, 11-kolo, Shadow+, dlhé ramienko GS

SK Kvalitná prehadzovačka, ktorú možno len doporučiť. Mám odkaz, pre toho, kto hľadá možnosť ľahkých prevodov pre gravel, moja skúsenosť: mám oválne prevodníky 44/34 a kazetu 11-42 a prehadzovač perfektne funguje aj pri nahodených španieloch.

Variant Shimano GRX RD-RX810 prehadzovačka, 11-kolo, Shadow+, dlhé ramienko GS

SK Dobrý deň. Mením kazetu na bicykli na rozmer 11-34. Používam systém shimano 105, avšak prehadzovačka daného typu s dlhým ramienkom je nedostupná. Mohol by som prehadzovačku GRX RX810 2x11-k. dlhé ramienko Shadow Plus použiť ako alternatívu? Aby bolo radenie pákami shimano 105 kompaktibilné s danou prehadzovačkou. Ďakujem, Ptáček.

Variant Shimano GRX RD-RX810 prehadzovačka, 11-kolo, Shadow+, dlhé ramienko GS

Good day. I know you already wrote that it will take a max of 34T gear, but the range of motion in the description is that it can go up to 40 teeth. Could this mean that the cj should take an 11-51 cassette?
