SK Vynikajúci chod a ľahučké nastavenie za 3 minúty. Dokáže po odstránení tej plastovej srandy na vnútornej strane tela prešmyku umožniť hladký chod reťaze aj pri nahodených španieloch.

SK Dobrý deň!
Mohla by spoľahlivo fungovať takáto zostava?
-radenie SH 105/starší model 6800/mechanická 2X11
-kľuky GRX 2X11/46-30/
-a tento prešmykač?
Pýtam sa preto,lebo priemer pôvodných klúk SH 105/50-34/je väčší ako uvedené GRX.
Bude teda možné na návarke ísť s prešmykom nižšie a tak dosiahnuť želanú kompatibilitu?
Ďakujem za odpoveď!

SK Dobry den,

GRX presmyky/kluky disponuju odlisnou (sirsou) retazovou linkou ako klasicke cestne modely - kombinaciu GRX komponentov s cestnymi sadami tak skor neodporucame.
