ProsAvailable 9 speed
To replace damaged derailleur on old touring bike. It works fine. Triple ring 9 speed set up with 4 different grades of Shimano on it. And it works a treat. What more could one ask?

Alternatives to a long cage?
16 Jul 2019
As a long cage is not available, will an Alivio long cage rear derailment work. I have SHIMANO ST-3503 SORA STI road levers. Triple chain rings 50-39-30 and a 9 speed 11-32 cassette. Alternatively which inner/outer plates would I buy to convert the Sora med cage to a long cage?
Any of our Shimano 9 speed MTB mechs will work with this combo in SGS copy and paste this link:

I need a long cage, as I run a triple chain ring. Do you have one or any suggestions?

unfortunately, we do not stock a sora long cage, however, we do stock them in different Shimano series such as Alivio although we do understand this may not be suitable for you.
Replacement for Tiagra 9 speed derailleur
14 Jun 2019
I want to replace a RD-4400 GS medium cage derailleur. Rear cassette is 12-25.

Would this Sora RD-3000 GS medium cage be suitable? Any other suggestions?
Yes this would work nicely.

Thanks - 14/06/19
would this sora medium cage be suitable for a 9 speed 11-32 cassette?
01 May 2019
Hi, yes, it is suitable for 11-34 cassettes. However if you want to run a triple chainring setup you should use a long cage mech. Thanks. 02/05/2019
Hi, which cage length do you recommend for a 11t-25t cassette and triple chainring?
22 Apr 2019
Hi, you will need a long cage rear mech for this set up. Thanks 23/04/2019
Can I use this derrailleur only with an 8 speed cassette and a 8 speed down tube shifter??
07 Mar 2019
Hi there,

You should get away with using that with this shifter, However, as we have never done this we cannot say for certain I'm afraid.

Can I use this with 11-21 cassette?
29 Oct 2018
9 speed BBB 11-21 cassette
A GS cage R3000 derailleur will take up to an 11-34, if you only plan to use 11-21 we would recommend a SS cage - SJS Cycles part number : 42944
