I have an SRAM x7 rear derailleur only been using it a few months (through the rain) and the jockey wheels seem in a bad way. There's a lot of side to side play in them and the teeth look sharp when i think they should be squared off at the top, I think this is causing issues in a couple of gears which won't setup correctly. The rest of the drivetrains is brand new and seems to be working fairly well.
Given how expensive jockey wheels are, Is it generally worth replacing the jockey wheels in a derailleur at this point, or is it better to get a new derailleur. Seems a waste as I think its been on the bike for 4 months max.
