derailleur

On looking through the posts r.e Derailleur Cage lengths I am now at a loss! 1) are short, medium and long cage lengths all set to standard lengths. and 2) do different manufacturers short, medium and long cages vary from one another? As I have a Shimano tiagra RD ( not sure of the model...

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...

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...

Hi folks, I've seen plenty of adapter bosses to mount downtube shifters and braze-on front mechs on tubes up to 31.8mm, but does anyone do them for 35mm tubes?.. I'm not asking for a friend, I'm asking because I'm building a full-Campagnolo Brompton drop-bar, and I'd rather use clamp on bits...

I have three pairs of new take off SRAM TT500 shifters, 2 pairs are unmarked, one pair has a scuff on the left hand lever. See here; Scuffed are £45, unmarked are £55 https://iansattic.space/shop/sram-tt500-bar-end-shifters-10sp/ Sram Rival Derailleur 10sp...

Hi, I need a new band-on front derailleur. I am planning on replacing a knackered Microshift jobby with a 105 5700. My bike is a 20 speed Boardman CX. The trouble is, I have no idea what band-on size I need! I measured the tube at 140mm circumference and divided by 3.14 as per GCSE maths (now...

Hi, One of my bikes is a Giant Talon 4 2014 and my gears were playing up so decided to tune them. I have performed the front derailleur tuning on another bike okay but I cannot seem to get the front derailleur to tune in on this bike no matter what I try. Please help. Front derailleur is a...

Bought a few years ago as I thought I needed one (I didn't). It's an RD-M360, useful for mountain bike and hybrids. Still in box, unused. £10 + postage, or I can whizz it round to you if you're in Central or South London.

Hi folks just put a new Ultegra 6800 11 speed groupset on my Ribble r872. Was wondering is it inevitable that I will get a bit of chain rub at the extremes ie big chainring big rear sprocket, I'm also aware about cross chaining. What's your thoughts and can you trim the front derailleur to get...

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?

Sold!

I seem to have misplaced my front derailleur for the work bike! Anyone got a 8 speed double braze on or 34.9 band on (I think). Let me know if you have anything and how much you want for it. Cheers

Yesterday, coming to the top of a hill I had to change down into the "help the aged" gear (small ring, biggest sprocket). When I did, I heard some almighty rattling and the chain seemed reluctant to engage. On inspection I found the chain to be really rubbing the inside of the derailleur cage...

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...

Hello all, I recently ordered a Shimano Zee derailleur because I had a pretty bad accident and snapped mine. I run a 1x10 drivetrain. A 32t chainring. A 11-34t cassette. However I ordered the short Cage derailleur, is this going to be a problem ? Thanks.

The front derailleur on my giant trinity had started to rub on the big ring slightly . I took the bike into my giant shop and they sorted the problem but on my next ride it started doing it again after about a mile . The shop has said the plate is slightly bent and they will replace it under...

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...

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

l have been having problems with my specialised racer the last couple of days, when l put pressure on the pedal or going up hill the chain was coming off. Anyway today l went out on the bike and the chain came off twice before a third time when the bike locked up with the chain coming off and...

Both items in great used condition. Calipers have used Clarke's pads fitted. £25 delivered for calipers and £12 delivered for the derailleur. Derailleur now sold.

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...

A new old stock Stronglight white crankset, 170mm with 52/42 cranks: http://www.ebay.co.uk/itm/162427619640 Sachs Huret rear derailleur, 1987: http://www.ebay.co.uk/itm/162428732166

While I changing the cables, I have lost the small piece which connect the cable to the rear derailleur. I googled it and it is not something that you can buy. What can I do?

hi guys. my girlfriend recently bought a specialized diverge (which is nice) but unfortunately on her first trip out she came off pretty bad. the right hand shifter was bent in and i managed to get it back into position. but after this she couldn't shift into the rear big cog without the chain...

My ultegra 6600 derailleur broke and now I am looking for a replacement 9 speed derailleur. It seems that the only new 9 speed road derailleur shops have in stock is the Sora 3500. I'd like to get a Tiagra or above, which makes me wonder what other Shimano derailleurs will take a 9 speed chain...

Hello, my rear derailleur plates got bent and I need to replace either the plates (which seem to be really hard to get) or a new derailleur. Any 9-speed Shimano GS Sora or better will do. Thanks!

What fun that was! My chain was slightly rubbing at one extreme of the gear set (I can't remember which end, I think the very lowest). So I looked on you tube for how to adjust it. Hours of absolute joyful entertainment :wacko: And it still rubs.......I have though, managed to get the set i use...

The rear derailleur on my bike seems to be set up perfectly but if I'm in a smaller cog on the rear cassette and the middle chainring the bike will struggle to go to the smaller chainring and I have to go one of the larger cogs in the cassette to get it to shift. What can I do to get it into the...

I've been cobbling together a bike over the last few months, and it's now almost complete. It needs some way to change gear though. It's 8 speed, so if anyone has an old 8 speed road mech in their bits box, I'd be interested. I've managed to get hold of a 105 front and Ultegra brakes, so...

I just picked up a bargain Surly LHT frame on ebay, currently drawing up a table of components for my DIY build but have been struggling with the gearing/shifters. I've only ever experienced drop bars with STI levers, and now want to give bar ends a go. I want to put on a triple crankset, and...
