Please, what is included in the ULTEGRA derailleur package, when you mention that the R8000GS package weighs 90g more than the R7000GS???
Thank you
•
Dobry den,
v baleni sa nachadza len samostatna prehadzovacka,a samozrejme sprievodna dokumentacia. Hmotnost samostatnej prehadzovacky je approx. 210g.
Balenie jednotlivych modelov/rocnikov je spravidla odlisne - iny tvar a velkost skatule - preto je celkova hmotnost dodavaneho balenia rok od roku odlisna, nevraviac o roznach modeloch.

Zdravim, GS ramienko zvlada max.34 zubov na pastorku, s kompaktom 50/34 bude kompatibilne 11/34? alebo treba dat 11/32? Dakujem za odpoved.L.
•
Dobrý deň,
Áno GS zvládne kazetu s rozsahom max 11-34z a bude to následne možné použiť s prevodníkmi 50/34.
•
Hello, can you advise me on how to get a longer screw to adjust the distance from the cassette? The original one is too short.
Thanks
•
Dobry den,
zial samostatne B-skrutky dostupne nemame Mozete skusit pripadne s povodnou skrutkou skocit do lepsich predajni spojovacieho materialu, kde Vam ju premeraju a pomozu vybrat vhodnu dlhsiu alternativu.
S akou kazetou planujete prehadzovac jazdit, ze je fabricka skrutka nevhodna?
•
Zdravim, kupil som u vas 11s kazetu 11-34.
•
Dobry den,
s 11-34T kazetou musi prehadzovac spolupracovat aj so standardne dodavanou skrutkou - https://bike.shimano.com/en-EU/product/component/ultegra-r8000/RD-R8000-GS.html (hodnota "Low Sprocket max").
Skuste pripadne doladit spravne nastavenie prehadzovacky podla https://si.shimano.com/en/pdfs/dm/RARD001/DM-RARD001-04-ENG.pdf.

Zdravim, posielam fotky mojho problemu a ako som to vyriesil ale je to nie uplne optimalne. neviem ci ma vplyv tvar pätky nakolko ja jedna o starší rám Spec. roubaix cca 2010
•
ahoj, táto téma je tu už skoro rok a zrovna riešim podobné. Previs reťaze pri maximálnom skrutkovom doraze. Tak ma napadlo, záves prehadzovačky pootočiť hore až nad pätku rámu. Prehadzovačka má dva neštelovateľné dorazy a pootočiť ju až nad spodný doraz. Tým sa záves prehadzovačky dostane viac do vodorovnej polohy (viď foto) a je väčší rozsah štelovania skrutkou. Neviem či som to dal zrozumiteľne, zle sa to vysvetľuje. Ale keď si spokojný tak ako to máš, tak nerieš.

•
Hello,
Will the Shimano R6800 bracket fit this? Or does the package include a new bracket? Or should I buy it separately?
•
Dobrý deň,
Ak myslíte držiak ako taký tak ten je súčasťou prehadzovačky. Pokiaľ myslíte pätku rámu tak na tú bude sedieť aj táto prehadzovačka a nie je potrebné kupovať inú pätku.
•
Hello, how do I know if I have the SS version or GS? Is it marked somewhere directly on the derailleur? Thanks for the answer

•
Dobry den,
ramienko oznacene nie je, avsak disponuje odlisnym tvarom - a samozrejme dlzkou. Viete to lahko opticky identifikovat pomocou produktovych fotiek:
- SS: https://bike.shimano.com/en-EU/product/component/ultegra-r8000/RD-R8000-SS.html
- GS: https://bike.shimano.com/en-EU/product/component/ultegra-r8000/RD-R8000-GS.html (vsimnite si iste zalomenie ramienka v strednej casti)
•
Ďakujem veľmi pekne, pomohlo
•
Hi, what cassette range can the short arm handle max. 30 teeth? I have a short arm Ultegra r8000. Thanks for the answer
Automatically translated
•
Dobrý deň,
Krátke SS max 30z., GS max. 34z.
•
Hello, is it possible to combine this derailleur with Ultegra cranks and an 11-speed cassette where the largest would be 42T?
Automatically translated
•
Ahoj myslim si ze nie, lebo podla popisu ked som ju kupoval mi bolo povedane ze je max do 39 zubov. Pekvy vecer a vela uspesnych cyklokilometrov😁🚴🚴
•
No ja by som to skusil ale pod podmienkou že maš dlhe ramienko na prehadzovačke. Jazdim 36z kazetu kvoli ktorej som daval dlhe ramienko. Alebo najisť odbrého mechanika ktorý poradí. Držím palce v pokuse. Daj vedieť tiež som nad tým premýšlal.
•
Dobry den,
urcite nie, prehadzovac je urceny pre max. 34T pastorky.
•
I would need both an inner and outer guide for this derailleur and pulleys that fit?

Hello, will it work with Ultegra CS-R8100 12s 11-34? If so, I order and thank you. Ales

•
Dobry den,
s 12-rychlostnou kazetou prehadzovacka nemusi fungovat spravne, je urcena pre 11-rychlostne modely kaziet/retazi.
•
Hello, I want to ask, will this derailleur also work on a 10-speed bike?
Automatically translated
•
Dobry den,
nie, prehadzovacka je urcena vyhradne pre 11-rychlostne retaze/kazety.
•
Dobrý deň.
Tento prehadzovač môže byť použitý na kazetu 11-34 ? Ďakujem
•
Dobrý deň,
Áno môže, 11-34 je naväčší rozsah kazety čo zvládne.
•
Hello, is this compatible with Shimano 105 7000 shifting? Thank you
Automatically translated
•
Dobrý deň,
pokiaľ máte ten istý počet prevodov tak nieje problém.
•
Dobry den, prosim Vas, kedy je budete mat na predaj. Dakujem
•
Dobrý deň,
aktuálne nevieme objednať ani z centrálneho skladu v Nemecku - nemáme žiaľ ani dátum budúceho naskladnenia.
•
Dobrý deň, bude fungovať so shimano 105 ST-5800 ? 11 sp.
•
Dobrý deň,
Áno bude fungovať.
•
Dobrý deň,
bude to fungovať s radením 6700?
•
Dobrý deň,
Nebude fungovať, použiť môžete ako jedinú dostupnú "náhradu" https://www.mtbiker.sk/shop/komponenty/prehadzovace/cestne/shimano-prehadzovacka-tiagra-4700-10-k-dlhe-ramienko.html
•
fungovalo by to s radenim 6800?
•
Dobrý deň,
Áno bude fungovať aj s týmto radením
•
je možné s dlhym ramienkom použiť aj menšiu kazetu(11-28)?
•
Dobrý deň,
11-28 je možné použiť ale to je minimum. Ak by ste chceli použiť napr. 11-25 tak by bolo potrebné vymeniť prehazdovačku za verziu s SS ramienkom.
•
Ak nie, tak viete prosím vás zohnať Shimano 105 RD-5701, ktorá funguje s radením 6700?

"Fun" for 12 hours of pure time. If anyone would try to set this up and you're a total amateur like me, here are some tips to shorten the setting time I adjusted my old derailleur (105) for about 5 hours, until I began to suspect that it probably has the best times for with itself (in my case, it didn't want to downshift properly), a new foot didn't help either (the old one was bent in the service, supposedly it was "needed"). A person thinks that he is doing something wrong (that's why he spends so much time trying and pretending), but in the end, the opposite turned out to be the case...
Automatically translatedSo I decided to go for a new one and upgrade it to Ultegra, because the price difference compared to 105 is not that big. So I "installed" the derailleur on the new foot, but the desired result compared to the old one was not very good. After 5 hours of waiting (and nerves), I decided that something was going to be wrong. The first thing that turned out to be bad was the cable, the inside of the clutch started to wire, so it was replaced. It started to get better right away, but still not the same. After 2 hours, it was time to change the bowden, it was together with the derailleur, but I left the flood one from the 105, you know what can "go wrong" in such a pipe. Well, this exchange turned out to be a game changer. After 50 times, I go to adjust the derailleur, and immediately after replacing the bowden, I adjusted it to complete satisfaction in 10 minutes. Beautiful shifting up and down, without skipping or jerking. I did everything right the whole time, but I underestimated the details, that's why the exchange cost me so much time (at least I'm a bit wiser now )
It works perfectly. For the 25 euros or so that is the difference between 105 and ultegra, it is definitely worth it. Using the included cable is essential for proper functioning.
Automatically translatedI installed a larger cartridge and therefore had to install a GS-shifter as well, it is quick to change and after setting the position it also works on the 11-42z. (...)
