So I was sold a Shimano RD with a missing part (on ebay) & the seller will not refund - nice !!!
Anyway the missing part is the small thing that screws into the back of the RD that recieves the outer cable.
I hv found some Shimano parts on the internet and the thing that looks like it could be it is called the 'cable tension adjuster' - does anyone know if this is the part I need ?
If I am not making sense I could take a photo ?
