I’ve just bought a replacement 105 R7000 RD for my bike, as the shifting was getting pretty bad.
The price between just buying new jockeys wheels and a complete RD was about £10, after discounts/vouchers etc.

I understand that jockey wheels and cables wear out (effecting shifting), but does a RD?
Is a RD more of a: “it either works or it doesn’t” piece of equipment, or do they wear out, causing shifting problems?

Thank you.

Thank you. I don’t think they’re compatible with 11 speed?? It says 9 or 10 speed.

Tom_77 was replying to Cdl888 who mercilessly hijacked your thread to ask for 9-speed jockey wheels. You’ll want 11-speed ones if you’re going to replace them.

Thank you.

A bit of play in the jockey
A bit of play in the jockey wheels is a good thing (within reason) – the mech is just guiding the chain onto the right sprocket and that sets the alignment. My 1988 Suntour is working very nicely on a new Tiagra cassette, despite years of salty roads and general neglect. Perhaps they don’t make ’em like they used to.

I realise I have gone a bit Fred Dibnah.

Jumping in on this one. How specific are jockey wheels on shimano mechs? I have a Sora 9 speed equipped bike on my turbo that needs new jockey wheels but I’m unsure which I need. Any suggestions?
 

The ones I bought have a list of what they’re compatible with, think 3400 and 3500 are Sora. Got them from Amazon:

Oops – didn’t spot that they

Oops – didn’t spot that they were out of stock (I usually tick that filter box when shopping for myself).

Here’s some suitable ones on EBay: https://www.ebay.co.uk/itm/132888210884?var=432187554870

Those ones suggest that 7,8 and 9 speed jockey wheels are all compatible, so some shopping around may find some cheaper ones (or colourful aluminium ones).

It can be tricky to spot mis

It can be tricky to spot mis-alignment of rear derailleurs, but I’d expect any problems to make themselves known quite soon after the damage. I’d go for cables first as jockey wheels can easily last longer than 9,000 miles.

Well I totally agree they
Well I totally agree they shouldn’t be confusing at all, but Wiggle there highlight the main problem, none in stock of that version, havent been for months, and you’ll struggle to find anywhere online that does of that specific part, maybe a LBS have a drawer full of them but its difficult to find Shimano spare parts online for their lower range groupsets, you tend to find you have to use their 10speed components, so RD5700s are a good match, instead, but accept it’s not quite like for like replacement.

Why Shimano cant just produce a set of generic bike bits, rather than hide it all behind multiple codes and keep changing them,making it feel like they are constantly reinventing the wheel all the time I dont know. It’s like they think by the time these bits wear out,people just buy a new bike instead.

The main spring will fatigue over time, as will the main pivot bushing. But R7000 is pretty new so I’m surprised it’s already worn, unless you’re doing mega miles?

Thank you ? Just less than 9,000 miles done on the bike, but there are lots of hills. So plenty of gear changing.

I’d expect a derailleur to last a lot longer than 9,000 miles even with a lot of shifting. Far more likely to be jockey wheels and/or cables unless you’ve had some impacts on it.

I did crash the bike back in January on some black ice, on its drive side.
But ouch, the skin on my hip/leg took most of the damage.
I can’t say I noticed any shifting problem directly after that time though.

Can’t say that I’ve used Sora 9 speed, but I think jockey wheels are one of the less confusing bike parts so you just need to go for 9 speed jockey wheels (though I’d ignore Campagnolo ones as they’re more likely to be incompatible with Shimano in general).

Wiggle only seems to show these ones: https://www.wiggle.co.uk/shimano-rd-m430-alivio-9-speed-jockey-wheels

I’m in a similar situation. I looked at prices and new jockey wheels were £11 and a new derailleur was £45, so I bought the jockey wheels. I have yet to fit them.

So did you manage to get a new derailleur for £21, and if so where?!?

Halfords.
I used a combination of British Cycling discount, various Halfords vouchers (the type they give out when signing up to their email newsletter and when you give them your vehicle reg. no.).
I also got £10 off, because when I ordered the RD from my local branch, it showed as being in stock. But when I went to collect it, it wasn’t. So complained via online chat, asking for a £10 voucher, as I’d wasted my time.

I looked around at jockey wheels, but didn’t see any at £11.
Can you post a link to those, please?
