Does Campy sell 12 speed individual cogsets?

[cgolvin]

One nice feature of the 12 speed [Chorus] cassettes is that only the upper triple varies among the 3 configurations. I have 11-32 (25/28/32 upper triple) but would be interested in buying the 25/27/29 to swap in when the route doesn't have really steep pitches.

I have bought these upper triples for 11 speed but can't seem to find them for 12 speed. Does Campy sell these as separate items, and if so do you know where/how to locate them?

thanks

Actually, the 11-29 does not have the same two sets of 3 sprockets. The 11-29 goes 17-19-21, then 23-26-29. The other two go 17-19-22 before the last three sprockets and the timing would be off, if mated to a 23-26-29. The 22-23 shift would also be mostly worthless.

All of the three sprockets sets have a separate part number. You can convert your 11-32 with the 11-34 last three sprockets and have the correct timing.

Thanks (though I think the highlighted "11-32" above should be "11-29", yes?)

Good news, bad news..part numbers. If it has a part number, it IS available as a small part...finding it 'might' be a challenge tho and undoubtedly it's going to approach the price of a whole cogset.

Yes. I fixed it.

Thanks Peter, but now I'm confused -- you wrote 25/27/29 for CH369 but I think that triple is 23/26/29 (the part name would seem to indicate that too).
