SK Zdravim, objednal som si https://www.mtbiker.sk/shop/komponenty/kluky-a-prevodniky/prevodniky/shimano-slx-sm-crm75-prevodnik-1x12-p87253.html, ale zial kvoli vytrcajucim skrutkam na zadnej strane mi nevojde do ramu. Viete mi, prosim, potvrdit, ze tomuto vzadu nic netrci, kedze je z jedneho kusu? Dakujem.

SK Dobry den, ano, tento prevodnik nema ziadne atypicky pretrcajuce casti alebo kovanie, ani z vnutornej strany.

SK Dobrý deň. Bude tento prevodník sedieť na kľuky XT-8100, Je uvedená reťazová linka 55mm, na mojom ráme je uvedená 52mm (čo som aj nameral s prevodníkom SM-RCM 85). Zadný náboj je samozrejme 148mm. Bude to fungovať? Nebude tam problém? Ďakujem za odpoveď.

SK Dobrý deň,

ak máte teraz štandardné Boostové kľuky, tak žiaľ po osadení tohto prevodníka bude reťazová linka naozaj 55 mm - t.j. os reťaze bude ďalej od stredu bicykla, pri radení na ľahšie prevody (väčšie pastorky) bude teda kríženie reťaze väčšie - pohon môže byť celkovo hlučnejší a rýchlejšie hrozí jeho opotrebenie.

SK Teda keď kľuky 8100 majú reťazovú linku 52mm a kľuky 8120 – 55mm a prevodník (sm-crm85) je rovnaký, zmena reťazovej linky sa mení zmenou kľúk nie prevodníka. Otázne je či prevodník sm-crm86 a 85 sú rozmerovo rovnaké – majú rovnaký offset a je tam len iný dizajn.

SK Staršie prevodniky - CRM85 - majú 3 mm offset, tieto nové už potom 0 mm. Čiže podľa špecifikácie Shimano je to naozaj inak už nielen pri samotných kľukách, ale aj pri príslušných prevodníkoch - reťazová linka sa tak nemení už len zmenou kľúk.
Aké máte teda presne kľuky, len pre istotu ešte raz M8100?

SK Zdravím,
Tento prevodník by teoreticky mal sedieť na kľuky Shimano Deore XT FC-M8100?
