Campy derailers with DT shifters on MTB
Currently have 3x9 MTB drivetrain on my Riv. Front: 44/34/24; Rear: 11-32. Dia Compe friction DT shifters.
Would 9-sp Campagnolo derailers work with this set up? |

Get a Racing T RD

Wow, they are not cheap, are they?
I did find a Veloce triple FD. Hope that will work. Rear: I’m hoping any 9-Sp RD med/long cage will work with MTB spacing. The Racing T RD on eBay is $200. |

Friction shifters don’t care what brand of derailleur is at the end of the cable.

A brand new $60 centaur mid cage will work fine for that setup

That's true, but as the number of sprockets increases (and the spacing between gets smaller), friction shifting becomes more fiddly, and allows less error in shifter position. 9spd is probably on the edge of okay, but I don't think I'd want to friction shift 12spd.

None of the 9s-era Campag derailers were rated for larger than a 26t cog iir, so issues with max cog size may come up as a mere 29t cog is installed.
I have used the long-cage versions of 9 and 10s Campag rear derailers with 29t, but I got the feeling when setting them up that I was at the limit. I recall that there was one particular version (of three choices) of the 10s rear derailers over the years that was made to accomodate 29t, but I recall getting the middle version to work that I think was only rated for 26t. |

My question is, if I get a 10 or 11sp RD, and pair it with the friction shifter and 9-speed cassette, will that cause any issues? Specifically regarding the cable pull ratio? |

Any pull-ratio differences will be slight, far too small to affect choice of friction-shift levers. One thing that can reduce sensitivity of friction-shifting narrow-spaced cogs is the use of narrower chain than the cogset normally uses, so use of a newer derailer and chain might likely work the best overall. And some chains are definitely less tooth-grabbing than others! I can recommend SRAM 9 and 10s chain as being less tooth-grabbing than Shimano's 9 and 10s chain. Normally this can result in poor indexing when using SRAM chain on a Shimano drivetrain, but with friction shifting it's a definite advantage! So I would recommend a one-increment narrower (than the cogset) SRAM chain for use on a friction-shifted 9 or 10s cassette. |
