Record Shifter/RD Compatability

Is a Record 10s right shifter from 2004 compatible with a Centaur RD from 2011.

I have these installed but find it impossible to get the shifting right. When shifting smoothly in the larger cogs it's a bit off on the smaller ones and vice versa.

should be. all cable pull data i found on 10s campag stated the same thing.

is the cassette new? if not, is it custom built? spacers are not the same thickness throughout the range/ratio

also, some useful info here:

Bought the cassette from new and it was shifting perfectly through all cogs with a Centaur 2011 PowerShift Lever.

Here are the cassette details

I only switched it out as I wasn't happy with the Centaur left shifter so switched the pair out to Record 2004 that I picked up second hand. I had to put a new G spring into the right shifter.

I will try fine tuning the shifting again but it shouldn't be this hard. Had no problems adjusting the previous setup.

Well I spent a good 15 minutes tweaking it and I haven't managed to make it much better. It's not out by much but in some cogs I get a little clicking that tells me it's not perfectly aligned. It never fails to find a shift correctly though.

Only thing I can think of now is to thoroughly clean and lube the drivetrain and then possibly consider disassembly of the shifter for a clean and lighter regrease.

After that it may be a new chain and cogs.

cassette lockring torqued properly?

Good suggestion. Checked it and it's good and tight. No lateral play in any of the cogs.
