derailleur

Hi I have a Cannonade synapse 2016 with Ultegra Di2 gearing. Over the last year I have had problems with shifting on the front derailleur. The front derailleur is over shifting and causing the chain to come of on the outside of the chain ring. It started when going downhill and in 50/11...

I've just acquired a Sun cycle with the above deraillier. I've tracked down a NOS tension spring, and the rest of the mechanism looks like it will clean up well. The cable is a continuous cable which is in tact but just thinking out loud where and how do you replace these? Picture for reference.

The other day I noticed when I shifted into the last 2 biggest gears chain would rub against front derailleur. I tried to tension it but made it worse. What's the best way to do it achieve maximum tension. Step by step guide would be nice. Thanks

Hi is it possible to use an 11 speed derailleur with a 9 speed cassette?

Inspired by my other thread about winter, and this video that I posted on YouTube a couple of years ago, I wondered if anyone has any recommendations for alternative derailleurs that aren't fully enclosed with the chain guides so they're easier to clean. View: https://youtu.be/E4nh0aEiBeI Be...

My daughter took a little spill today, she's fine but the bike hit the tarmac hard and the derailleur took a hit. The hanger has bent in a little which is forcing the chain off and into the spokes in low gear. Is it overall cheaper / less faff to buy a new hanger or is there mileage in...

I'm building a Frankenstein bike out of salvaged spare parts , its going to be a 1x , 22" Coyote hardtail MTB frame,rigid forks, minimal gears, an mtb touring hybrid kind of thing built for comfort and load carrying with panniers. I've rummaged in my pile of bits and come up with these Shimano...

Shifting is poor and when in any gear it isn't smooth. I've tried to adjust tension etc but it makes little difference. There is some play where the mec attaches to the hanger but tightening the relevant bolt makes no difference. Does anyone know why this is the case? I have fallen on that side...

Hi All, I am riding a Ridgeback Voyage which has a triple chainset at the front. As part of a recent service at an LBS, they changed the cable which had become frayed. Unfortunately, as a result of this, they have introduced a fault whereby changing down from the largest ring, it jumps...

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...

Brought this from Evans about a year ago as ex-display, test fitted it but never used and couldn't be bothered to return for a refund. Cosmetic scratch as per the pictures - £10 delivered with payment by Paypal or bank transfer.

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...

On my way in this morning the chain hopped off the front crank, now I can’t get it to shift to the large crank. How do I adjust, sorry for the probably silly question but I leave gear adjustment to the pros usually. Edit: when I lean the bike over towards the side with the gears it’s will...

I have a Shimano 105 groupset and no matter how I adjust the front derailleur the chain still catches on the guard when in the smallest gear and on both big and small ring. If I manage to adjust it to stop the catching I lose the ability to choose the highest gear. It's almost as if there is...

I'm after a 10 Speed medium cage 105 derailleur but can only find them in black. I'm sure they used to come in silver and would prefer that to match the aesthetics of the other components I have. I don't suppose anyone knows where I can get hold of one? Have tried searching all the retailers...

I currently have a sram red set up with 50/34 chain set and 11-28 cassette (10 speed). I want to run a bigger cassette - 34t (don’t judge, I have my reasons!). Any advice on which rear derailleur would be compatible? Most road/gravel derailleurs I’m seeing that take 34t are 11 speed. I’m not...

I was having a chat the other day with one of the guys on my train that has a Birdy Folder. I was moaning about climbing the hill out the station and saying I might fit a smaller chainring (which I've done), and he said can't you fit a front derailleur and two chainrings? I did a quick search...

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...

Hello I've been upgrading Shimano Revoshift to Tourney Thumbshift (SL-TX50) on my son's bike (Python Rock). Rear derailleur was really easy and no problem (and much improved shifting!) but front one is causing me a headache … The main issue I have is that the shifter "maxes out" half way round...

A new experience for me. I heard it snap. I wondered if something had broken. I was in the lowest gear, waiting at the lights. Off I went, tried to change gear, no change gear. I looked and saw that the hook at the end of the spring had snapped off. I can see the shiny metal where it...

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...

Anyone got a spec sheet for this? What are the cassette teeth ranges for this mech, I've done a bit of Gooling but not found anything Thanks in advance

Hi All, My bike came with an SRAM Rival 1 (long cage) rear derailleur. I'll be leaving to travel Asia in the next few months and I want to take a spare derailleur. I'm pretty good with Shimano but I'm now aware of the finicky side of SRAM so my question is this: Can I use another cheaper SRAM...

I want to convert a 9 speed road bike to flat bars and have some 3 X 9 acera shifters. I wondered if they would work for a 2 speed front set up?

Hi I'm in the process of replacing my gear and brake cables, frst time I've done this. I have fitted The front derailleur cable but have not attached to the front mech. I thought I'd check that when changed gear, it actually pulled the cable, it didn't. Is that normal ? They are ST5800...

I have an old British Eagle MTB with 18 speed Shimano Uniglide. I have two questions; The chain (KMC) is approx. 4 years old and has been regularly cleaned and oiled in situ. I have measured the chain and it has no stretch yet. I would like to take the chain off and soak it in some kind of...

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...

As above really, I do about 16 miles a day and a 1000 ft of climbing, are they any good?

Used for 3000 miles. Very tiny mark on side, see 1st and 3rd pic, otherwise excellent. £25 plus post Paypal gift or bank Tx

A quick update about me and my SunTour Cyclone. It just arrived. I opened it. Very happy. Let me know if you want pictures and I'll see if I can upload a couple.
