CS Oproti eTh*** přestal padat řetěz. Je trošku víc ven (od kola) a zdá se že má i lepší vedení. Za mě super.

SK Dobry den, mam doplnujucu otazku k tomuto prevodniku. Niekto tu v recenziach pise, ze oproti e*thirteen E-Spec je viac odsadeny od ramu. Viete to protim specifikovat? Pretoze uz aj tak je krizenie retaze pri pouziti najvacsieho pastorku vzadu extremne. Pri odsadeni od ramu vacsom ako ma e*thirteen E-Spec prevodnik si to uz ani neviem predstavit. Viete to fyzicky porovnat, odmerat alebo? Dakujem..

SK Dobrý deň, áno tento prevodník by mal mať ešte priblibližne o 2-3 mm vačší offset. čo sa týka kompatibility a funkčnosti záleži aj na ráme aký máte ideálny Chainline na ráme, Aký je rám široký alebo aj akú používate kazetu.

SK Dobrý deň. Mám elektrobicykel GHOST E-Teru B Pro 29 s motorom Bosch Performance Line CX a prevodníkom e*thirteen E-Spec 34T. Prevodník je optrebovaný a preto sa chcem spýtať, či ho môžem nahradiť s prevodníkom Race Face prevodník pre Bosch Gen4, CL 52mm Shimano 12Speed, alebo aký 34 zubový by ste mi poradili. Pôvodný e*thirteen sa rýchlo optreboval.

Vopred ďakujem za odpoveď.
Peter

SK Dobry den,

ano, na nove Bosch motory 4.generacie bude tento prevodnik sediet, mozete ho pouzit.
Dizajnom zubov (frezovanim) je predurceny na pozuitie s 12-rychlostnymi systemami Shimano HG+.

SK Dobry den,

zial RF kompatibilitu s Gen5 motormi priamo neuvadza.
Prevodnik moze sadnut, interface je identicky, problemom moze byt prip. len prip. ina prachovka, prip.vzhladom na odlisny dizajn tela motora taktiez priechodnost okolo ramu a pod. - mozete vyskusat prevodnik nanecisto zalozit, a ak by nesedel, tak samozrejme nie je problem vratit (https://www.mtbiker.sk/shop/informacie/vsetko-o-nakupe.html#vratenie-a-reklamacie).
