Shimano GRX RX817 Di2 rear derailleur, 1x11, Shadow+
Shimano GRX RX817 Di2 derailleur
Gravel bikes are becoming increasingly popular among cyclists. The advantages are obvious. They have a more comfortable geometry than racing bikes, are excellent off-road and are suitable for longer journeys. However, conventional racing bike components have reached their limits on these bikes. That's why Shimano developed its own gear groups specifically for this type of bike.|
The built-in stabilizer reliably prevents chain rubbing and keeps everything in place.
|
|
Ensures high shifting accuracy even in the most difficult off-road conditions
|
|
The Shadow's compact design not only looks good, but also protects the rear derailleur from damage in a fall

Dobrý deň
Mám teraz mechanické Grx 1x11
Prosím Vás bude stačiť tato prehadzovacka a vemit len pravú páku za https://www.mtbiker.sk/shop/komponenty/radenie/cestne/shimano-grx-set-strx815rbrrx810r-prava-paka-a-strmen-11-k-di2-radhydrbrzda-.html
A láva môže zostať mechanická ? Bude potrebovať asi ešte baterku a káble tie su súčasťou balenie prehadzky alebo páky alebo treba ich zvlášť dokúpiť ?
Ďakujem za odpoved

Dobrý deň,
Páku bude stačiť vymeniť len pravú ale nakoľko tie páky nie sú tvarovo identické tak ich nebudete mať súmerné a každá bude iná. Dokúpiť bude potrebné 4 káble, 2x konektor (jeden riadiací a jeden spojovací), batériu a nabíjačku (všetko sa predáva samostatne a spolu toto nevyhnuté príslušenstvo vychádza na cca 470-490 EUR v závislosti od dĺžky káblov). V prípade záujmu nám napíšte na email [email protected] a vyberieme Vám vhodné diely.

Ak tomu rozomiem správne bude treba prehadzovacku brzdovú páku plus ešte príslušenstvo za caa 470€. To sa už pomaly oplatí prerobiť na sram 🫣
•
Dobrý deň,
Rozumiete tomu správne, Di2 je nákladná záležitosť. Zasa pri prechode na Sram treba počítať ešte s kazetou, orechom (12 sady využívajú XG kazety určené pre XD orechy), komplet radením s brzdami a kľukami pre 12 sp. reťaz.

Dobrý deň na svojom bicykli mám systém GRX DI2 2x11. Dá sa táto prehadzovačka zameniť jednoducho za model RD-RX815 ktorí tam mám osadený teraz. Viem že táto prehadzovačka RD-RX817 má v špecifikácii napísané 1x11. Ide mi o to že keď jednoducho prehadzovačku zamenim či bude komunikovať pekne s prešmykovačom a celým systémom tak ako moja stará RD-RX815. Dosť jazdím v kopcoch a potreboval by som ľahšie prevody tak preto to riešim. Ďakujem pekne za odpoveď.

Dobrý deň prajem,
žiaľ Shimano kombináciu RD-RX817 a 2x prevodového systému neodporúča - ramienko tejto prehadzovačky má o niečo nižšiu kapacitu (31T) ako RD-RX815 (38T) danú iným tvarom ramienka, čo môže spôsobiť neschopnosť využívať celý rozsah prevodov.
Poznámka "pod čiarou" - žiaľ osobne to overené z vlastnej skúsenosti nemáme - teoreticky to pri dobrom vyladení môže fungovať k plnej spokojnosti, ale zaručiť Vám to nevieme. Môžete prípadne skúsiť napísať do nášho fóra, či náhodou niekto nemá osobnú skúsenosť - možno napr. do tejto témy - https://www.mtbiker.sk/forum/cestne-cyklokrosove-bicykle/cyklokros-gravel-t39856.html?hilit=grx.
V prípade akýchkoľvek ďalších otázok nás neváhajte kontaktovať.

Dobrý deň prajem.
Mám na bicykli osadenú sadu ultegra Di2 6870, pri páde sa mi zlomila zadná prehadzovačka a nenašiel som už nikde predaj novej, bola by táto RD-RX817 popprípade RD-815 kompatibilná zo sadou 6870? Poprípade je nejaké riešenie?
Ďakujem
•
Dobrý deň prajem, prehadzovačku môžete použiť, avšak kapacitne je určená len pre 1x11 setupy - vid'. tabuľka kompatibilít jednotlivých Di2 komponentov tu: https://bike.shimano.com/content/dam/one-website/common/products/apps/e-tube-project-professional/image/HM-CC%205.3.2-00-EN.pdf
•
Dobry den. Este otazocka: V pripade, ze by som chcel namontovat tuto prehadzovacku na bicykel s rovnymi riadidlami, je moznost ako ju sparovat so shifteroˇ na rovne riadidla? Dakujem.
•
Dobrý deň,
Jediné kompatibilné radenie pre rovné riadidlá a túto prehazovačku (resp. aj iné 11 rýchlostné cestné/gravel prehadzovačky) je SL-RS700. V prípade záujmu môžeme preveriť dostupnosť u výrobcu. Iné 11 rýchlostné radenia pre rovné riadidlá určené pre MTB sady žiaľ nie sú kompatibilné.
