derailleur

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...

I need to replace my sram derailleur on the Montpellier. It has flat bar therefore trigger shifters. I have looked at the sram apex derailleur but this is a road mech. Both it and the mech it is replacing use sram exact actuation which gives a 1:1 pull ratio. Is it likely to work here or will I...

I need a sram rear mech for use with10 speed 11-32 cassette on my fast hybrid. Reliable, good quality v cost, anything on a deal you know about? Don't really want to go above £50. TIA.

Hi all, I'm having some issues with the front derailleur on my new bike (Giant Contend SL 1). In the lowest gear (large back, smalll front) no matter what I try, the derailleur won't travel far enough inwards (towards the frame) to stop the chain rubbing against the plastic plate on the...

Right, I've been having shifting problems for a while. I can shift down the first 5 gears {from smallest Sprocket going up the block} fine by then the last 5 I have to hold the lever for a second or two to shift down and they sound a bit chatty. This is in the big ring up front. In the small...

Looking for a nice example of a 6700 rear derailleur medium cage or the later 6700A that goes up to a 30t cog. Thanks

I have a set of 6800 front and rear derailleurs for sale. Front mech is band on, rear is a short cage so good for up to 28 tooth cassette. Few stuffs on both as shown on pics but fully functional with no play in the jockey wheels. Based in Chester for collection or will post out. Looking for £30

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...

Realise that this is a long stretch but does any one have one of the above that they would like to sell? Thanks

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...

Hey guys :) I'm still in a pickle of setting up my 1940's Simplex Tour de France changer aka derailleur (this derailleur was called changer back in the old old days) and cycleops recommended me to ask someone on here who has messed with this type of derailleur before to get some tips and...

My favorite SunTour model is the VX, but I'm a huge lover of all of the other models as well, except the SunTour Wide. What is yours?

as mentioned in another post I have fitted an 11-36 cassette on my road bike with help of a Wolfs Tooth Road link , all is well but it is a tad lumpy/jumpy going through to the high gears , I been playing around with the barrel adjuster but can’t seem to tweak it just right , it shifts to the...

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...

Used Campagnolo Veloce 10 speed RD (short cage). My research tells me this is the circa 2009/2010 model (do correct me if I'm wrong). 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...

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...

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...

I watched the mailman go by my house, opened the mailbox, saw a package in it, carried it into the house, opened it up and got a surprise. I got my 1940 era SIMPLEX Tour de France rear derailleur. I'm saving it for when I either find or build my own French Tour de France bike, and I will learn...

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...

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...

Very happy to say got my new ''second'' SUNTOUR VX rear derailleur in the mail today. I forgot to add earlier I'm currently riding on a Shimano Tourney 6/7 speed derailleur on my 80's Fuji S12-S LTD road bike. Amazingly, it's working with my vintage friction CHARGER levers. Going to keep my new...

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 :=)...

Taken from the eBay auction where I purchased from last week, needed a larger fitting one: Thanks for looking at my listing for this Shimano Ultegra FD 6800 10 speed front derailleur. The derailleur was used on a road bike on two rides totalling less than 100 miles. It is a 31.8 clamp on...

SRAM X7 Front Derailleur 2x10 Dual Pull Low Direct Mount 42T Max Brand new in (tatty) box https://www.instagram.com/p/BfTKEoFgmGJ/...

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...

Morning, I may be replacing my rear mech, at present I have a Sram via GT groupset on my 2014 Whyte Montpellier. https://www.sram.com/sram/urban/products/via-gt#sm.0000y095ehuzdfi10p12i61j5mvuh https://www.avonvalleycyclery.co.uk/850152/products/whyte-2014-montpellier-carbon-hybrid-bike.aspx...

Hi all, this is on the whyte montpellier hybrid. I've been having some shifting issues in the lower 3-4 gears in both the big and small ring, needing a little extra push on the shifter to get it into the next lowest gear (biggest cog), also a little bit of chatter. I'd been fiddling with...

Hello. I am building (another) road bike from my spare part "store". My friend has told me I shall need one of the above. What is it used for ? Thank you for any replies.

Hoping someone can give some advice on the problem I am having with shifting between the 2 front rings on my Sirrus. The shifter was stiff but operating, but then the chain stopped moving to the big ring. The problem was fixed but returned after a few days. I then took the bike to the LBS for...

Hi folks... For my current project I kind of need to sort out an 7/8-speed Campagnolo setup... for perfectly good aesthetic/pose reasons I'd like to use Syncro (II) gear shifters.... my issue is I need to deal with 32 teeth's worth of chain wrap... kicking around in the box is a rather tatty...
