2007 Record Rear Derailleur pulleys
I need to replace the pulleys on my 2007 Record 10-speed rear derailleur (carbon cage). All of the listings I can find for Campy pulleys specifically exempt the 2004-2008 Record RD's. The Campy website spare parts catalog lists the pulleys as RD-RE600 with a width of 8.8mm but Lickbike shows this pulley as a 9-speed component. I'm confused. Can anyone help me find the correct pulleys?

Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter

I don't know if they changed later on, but for many years 9s and 10s pulleys were then same.

Just curious why not use a Shimano technology patent "Centeron" top pulley? Wouldn't it improve indexing performance on that era of Camp derailleur?

For whatever reason, Campagnolo replaced Record derailleur 8.4mm RD-RE700 pulleys with RD-RE600 8.8mm in 2004. Maybe they did that to get more chain clearance from the carbon fiber outer derailleur plate which is easier to abrade than the previous year and lower gruppos' aluminum part.
The pulleys are marked for 9 and 10 speed use; although I always assumed that was just Campagnolo using the same plastic piece with different metal bushings to change the overall width.

Thanks, all, for the responses. I'll go with the RD-RF600 pulleys.

Third parties can and do make mistakes or occasionally misunderstand, or are not wholly scrupulous in checking - since the Chorus 10s jockeys (and all those of the other 10s groups) were all listed as 8.4mm width, maybe this vendor just made an assumption?
Campagnolo don't always tell us *why* they make a change but in this case, since the change in part number is allied to a change in the spare parts code for the derailleur cage complete, (RD-RE402 migrated to RD-RE002S), and is also associated with a model year number change (RD00-RExx to RD4-RExx) it will almost certainly be the result of a revision in the exact shaping of the jockey cage plates. I don't have an old Record RD with a RD-RE402 cage to check here at present but that would be my bet.
