    Rear Derailleur Question

    Going from 8 to 9 speed... Does a 9-speed mech travel any different distance to an 8? The cassettes are the same overall size, no? Just wondering if I need change to a specific 9er if all else is changed, ie cassette and shifters...

    Rear derailleur installation issue

    Been trying to fit a new Shimano XT rear derailleur with 11-46 sunrace cassette but having issues with derailleur (tension?) When in 46T ring the top jockey wheel sits just on the cassette teeth but as soon as you move down the gears it's terrible and doesn't hold position at all. Nightmare! by...

    105 rear derailleur missing screw..?

    Hello :smile: I had an off and on inspecting the bike I noticed there appears to be a screw missing from the rear derailleur? This is on the underside near the cage section.. can anyone tell me what this screw was for, and if it might stop me nursing the bike home? Upside down the bike...

    Rear derailleur not shifting to smallest cog.

    Following on form last nights ride showed the gears needed a bit of indexing. On closer inspection and after the normal barrel and limit screw adjustment tricks to get shifting to the smallest cog the shifter has no more clicks left either. But still will not move to the smallest cog. Any...

    Rear derailleur not shifting into lowest gear

    Hello. I've just bought a Triban RC520 from Decathlon. However, the rear derailleur (Shimano 105) wasn't shifting into either of the lowest two gears (small chainring and biggest two cassette cogs). So having googled the problem, I did the following: Pushed the derailleur with my fingers to...

    Does anyone have an exploded diagram of a Campagnolo Victory rear derailleur

    Not fussed which one.... I did take photos before I stripped it, but I have subsequently lost the phone :-( I guess even one of a Triomphe would help, or a late Nuovo/Super Record (cos they're pretty similar). I would even be happy buying a tatty example to use for reference...

    Rear derailleur problem....

    I am having problems with the 7 speed Shimano rear derailleur on a Raleigh Siren in that it will not shift into the largest cog on the cassette. It moves smoothly between the other six cogs on all three of the front chain rings. Before I start messing around adjusting screws etc can anyone on...

    Rear Derailleur - life expectancy?

    My Shimano 105 rear mech has seen approx 3,788 miles of use, two offs and various mashing and tweaks to keep it in working condition. I run a compact double with an 11-28 cassette on the back and the mech has never been serviced bar replacing the jockey wheels. In the small ring on the front...

    Is it true you can thread your chain through a SunTour rear derailleur cage without splitting chain?

    I read somewhere a long while back, can't remember where I read it at but I do remember what it said. Someone wrote on this site that you can thread your chain through a rear SunTour derailleur cage without splitting it. One of my closest friends who rides and works on bikes, too told me you can...

    Shimano Tourney 6/7 Speed Rear Derailleur

    I have a question relating to something weird. From my understanding, modern Shimano derailleurs are supposed to work with modern STI levers for very new road bikes, but for some reason mine is working with vintage road bike levers that say CHARGER on them. The only info I can find on the levers...

    Rear Derailleur Shifts badly under tension

    As I have successfully adjusted quite a few sets of new cables to rear derailleurs I am surprised to find that am having a few problem with this, because after fitting new cassette,chain and longer cage rear derailleur find that whole gear changing operation works perfectly when bikes on the...

    Campagnolo 10-speed shifter with 9-speed rear derailleur - will it work?

    I bought some 10-speed Campagnolo shifters from somebody on the forum a couple of years ago and now want to put them on my old Basso to convert it to 10-speed. It was 9-speed up until last autumn when I took it out of service . I removed the worn-out Ergopower controls from that bike, scrapped...

    Removing rear derailleur - can front derailleur still function?

    Fixed my lad's bike multiple times but now rear derailleur is knackered - gone sort of saggy instead of being taut - so just wondered in the interim before replacing it - if I removed the rear d and then some links in the chain, would it still be possible to change through the three rings using...

    Rear Derailleur Cage Lengths

    Is the difference between a long cage and a short cage just the cage length? I have a short cage Ultegra mech, if I want the capacity to run a 32T sprocket can I simply fit only the cage element of a long cage Sora for example?

    Rear derailleur size?

    I have just bought a 'Shimano Tourney TX' to replace the 'Power Index System' one (which I assume is a cheap thing). I have just taken the old one off and compared it to the new one, I am amazed at the difference in size, the new one looks twice as big as the old one. I hope I haven't made a...

    Rear derailleur, again!

    Okay guys - I have a mid compact ultegra set-up 52/36 up front and 11-28 at the rear. Looking for a lower gear for hilly stuff. Going to buy a mid-cage rear mech, an 11-32 cassette and a new chain. Local Evans has them all in stock and is open today. What do I need to do with the new chain? Add...

    Rear derailleur

    Is this still okay or under too much strain? This is in 52/28: And on 36/11, will it take an extra couple of links: *And yes I know all about chain crossing

    Is this the Shimano short or medium cage derailleur?

    Can't find any identifying marks on it to work it out. I want to change the 11-28 to an 11-32 for a trip to the peak district in a few weeks and want to know if i'll need to change the derailleur. Cheers

    Clunky rear derailleur on lower gears

    A bit of a puzzler. On the smallest four cogs the rear derailleur is smooth. On the cogs larger it immediately is clunking, juddering. Recent history: Reindexed it last week, did some hills in the rain noticed it not shifting properly, did a turbo session with it clunking weirdly (tried to...

    Rear derailleur cable connector
