    Confused about a direct mount derailleur?

    I'm really confused about the meaning of direct fit on a derailleur. I currently have what looks like a a Shimano Tourney RD-TY 500 on my cycle. This derailleur hangs from a hanger on the cycle which looks like this (link below.) The bit I don't get is that all these direct fit derailleurs look...

    I currently have a SHIMANO TOURNEY RD-TX800 7 8 SPEED BIKE REAR DERAILLEUR GEAR MECH DIRECT ATTACH. Unfortunately, the guy who I purchased the Cycle from, he didn't tell me the derailleur had been threaded while fastening it onto the derailleur hanger at some point. This has left the derailleur...

    Why is there a V on the side of SunTour VX derailleur?

    I have a couple vintage SunTour VX rear derailleurs in my collection, aside the original one that was on my vintage Fuji bike. I love the SunTour derailleurs all models besides VX, but one thing that's confusing me is why there a V on the side of the derailleur? Maybe it's saying it's a part of...

    Campagnolo Veloce 10 speed rear derailleur short cage

Selling as its now surplus to my requirements and clearing out unneeded parts at the end of the academic year. The movement of the cage is smooth as far as I can...

    Need tips on setting up my 1940's Tour de France derailleur

    Hey guys. I need some tips on setting up my 1940's Tour de France derailleur, as I've never set up one of these ''odd'' and ''different'' breed of animals; if you catch my drift. I know that this derailleur works with only three cogs in the rear, and I am wondering if it will work on my 80's...

    What does GISU mean, or is it just the model name of the derailleur?

    Today, I got another rear derailleur in the mail. It's likely a basic cheap rear derailleur I know but it's a GISU INDEX SYSTEM derailleur. I had one a long, long while back, in 2013 to replace my stopped working original SUNTOUR VX rear derailleur. I've always wondered since then what the GISU...

    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...

    Is anyone here experienced with setting up a 1930's / 1940's era Simplex Tour de France Derailleur?

    I just bought a 1930's (OR) 1940's era Simplex Tour de France derailleur from ebay last night and I am just wondering if anyone here has set one up before. I hear they're a pain to setup because of the push rod/plunger design. Mine is arriving in a few weeks (coming from a foreign country :=)...

    Can I make the derailleur gap to the largest sprocket slightly larger?

    I have just fitted a replacement cassette with a wider set of ratios, it all fits and works perfectly with the single exception that there is next to no gap between the largest sprocket and the first slightly toothed wheel on the derailleur, in fact I think they are actually touching! I feel...

    6800 front derailleur woes

    having problems with this new set up. The front derailleur cable is supposed to go over the peg at the bottom of the bolt and come up the out side of the same bolt. Cabling up this way results in almost no shifting with an high resistance on the shifter. Shifting is much better with the cable...

    Ultegra Di2 6870 derailleur question.

    I currently have an Ultegra Di2 6870 SS (short cage) derailleur fitted but I'd like to increase the size of my cassette. Unfortunately, to do this, I'll need a GS (medium cage) derailleur. I'm assuming (and stand to be corrected) that the main part of the derailleur is identical on both and...

    35mm downtube shift adapters and front derailleur adapters
