What Shimano jockey wheels are compatible with my old Shimano 105 9-Speed Derailleur? I'm in the process of getting my Cannondale CAAD serviced, which I reckon is from about 2006 (I got it second hand). I have had the rear cassette and chain replaced, like for like, but the bike shop say the Shimano 105 9-Speed rear derailleur jockey wheels are very worn and may contribute to gear slippage and poor gear changing.

I can't seem to find jockey wheels specifically for the old 9-Speed 105 derailleur. Will the "Shimano RD 5700 Jockey Wheels" for the newer Shimano 105 10-Speed derailleurs be okay for use?
Here you go, VeloOrange has a part for that: http://store.velo-orange.com/index.php/components/shifting-freewheels-cassettes/parts-maintenance/vo-grand-cru-sealed-bearing-universal-jockey-wheels.html
