Dobry den, chcel som sa spytat na prehadzovacku, ktora nie je vymenovana v zozname kompatibilnych. Mam na bicykli tuto: SHIMANO DEORE RD-M4120, Shadow Design, 11sp. Tak ma zaujima, ci by to fungovalo aj s tymto typom. Dakujem.

Kvoli comu potrebujes predlzenie? Prehadzovacka by mala byt na 11-42 zubov. Chces prerobit na 1x11 a nahodit 50z kazetu?
Fungovat to bude aj s inymi prehadzovackami, mam to na Sram X9, este starej 9sp. Len treba pocitat s tym, ze oddiali kladku prehadzovacky nielen na najvacsom pastorku (aby ponalo vacsiu kazetu), ale aj na najmensom.
Ja som napriklad musel zbrusit doraz pre B-skrutku. Inak boli kladky prilis daleko.

Ahoj, chcel by som to ponechat v nastaveni 2*11, ale kazetu by som chcel dat 11-46 (ostala mi nova z ineho bicykla), a kedze prehadzovac nema taku kapacitu, tak som to chcel upravit tymto predlzenim

When I bought a second-hand bike years ago, I was switching from a 26" 3x9 DEORE to a 29" 2x10 XT. I suddenly missed the original gearing for hills. I was looking through the discussions, I didn't want to go to a 1x11 single-speed, I wanted 2x10 but with a wider range.
Automatically translatedI finally got the Microshift 11-48 cassette, but the problem was the derailleur, the XT doesn't have that range.
Based on the discussions, I had to play with other elements, but in the end I managed to fine-tune it. The derailleur remained the original Deore XT + I bought a hook extension (XLC CR-A28 here from MTBIKER) + I replaced the stop B screw with a longer one (a regular screw from OBI) + my chain is 114 links long.
This is how it works for me. Maybe it can be done without extending the hook, maybe it needs to be fine-tuned differently, but this is how I tested it.
It's been working for two years without any major problems: 2x10 cassette 11-48z.
Celkom to ide. Nie je to dokonalé, ale to s linkom nikdy nebude. Ale napriek kapacite GRX400 prevodov 2x10 a zadnej prehadzovačky GRX400 to dovolí pustiť kazetu dozadu na 11-42 a stále to radí skvele. Len pre porovnanie = maximálna kapacita pre GRX400 je uvádzaná ako 11-36 kazeta. A toto mi dovolilo rozsah až na 11-42.

Po 12 rokoch som prešiel z 3x10 na 1x10 prevodov a menil som preto aj kazetu 11/36 na 11/50. Predĺženie pätky prehadzovačky Shimano mi to dokonale umožnilo, radím hladko celý rozsah (samozrejme s predĺžením 10s reťaze o 2 páry článkov, samotný 1-prevodník 36 zubov).

Rozsah starej xtr prehadzovačky bol 36 zubov, vymenil som pôvodnú kazetu za 42z + tento hák a podľa mňa je tam rezerva aj na 46 zubov. Reťaz lepšie obopne kazetu čo je na úkor jej životnosti len veľké +. Lepšie ako kupovať novú prehadzovačku

Tak ako písal kolega predo mnou, použité pre Shimano GRX400 pre 11-42 zubovú kazetu. Radí v poriadku, ale je treba sa pohrať s nastavením.

Sram GX prehadzuje s týmto predĺžením aj kazetu so 46 zubami. Zatiaľ vyskúšané len na rovine, teším sa na hory.

Pouzity na prerabku 3x9 radenia na 1x9. Hak je prilis dlhy/ma velky sklon pre 11-40z kazetu. Koliesko na prehadzovacke je prilis daleko od kazety, aj ked je B-skrutka uplne zasrobovana (Sram X9 ramienko). Bude musiet podstupit jemnu upravu pilnikom.
