you might be really surprised on what you can fit on a xxx mech.. not sure if Campy is as conservative as Shimano, but I run an 11-36 on my Ultegra 8000 RD no problem without aids like a Roadlink.. changing the freehub might be the cheapest option to give it a try.. again, you may be pleasantly surprised..

An Athena long cage derailleur is spec.ed for 32 max. sprocket and a 40 tooth capacity. It can often be stretched to 34 teeth, but possible won't reach a 36 tooth sprocket. However, if should have plenty of capacity. Campagnolo 11spd speed drivetrains aren't designed for particularly large gear ranges, so rather than widening your gear range, it might be better to simply lower the gear range (with smaller chainrings). This will still allow a meaningful amount of flexibility, as there are some cranksets that will accept chainrings from 44/28 to 52/36. As far as the most "elegant" solution, that would probably be swapping to a SR WRL crankset. This would have the "Super Record" graphics to match the rest of your drivetrain, and it has chainring options of 50/34, 48/32, and 45/29, allowing you to swap chainrings for different conditions. |

Wow I just came accross this video on YouTube.

With the shorter cage and a geometry designed for a smaller maximum sprocket size, this setup would definitely not work with a 1st generation Campagnolo 11spd derailleur. |

Stupid question for those that know.. I know that all campy 10 speed could accomodate a triple - Did 11 speed come with a long/mid cage option?

The Athena Triple group had a long cage option; all others had short cage only. Ultra-Shift shifters (SR, Record, Chorus) were non-indexed. Theoretically they should shift a triple front derailleur, even though their derailleurs didn't actually have the capacity for a triple drivetrain. All other groups used Power-Shift shifters, which are indexed. Only the Athena group had both double and triple options, all others were double only. For 2nd generation (2015+): Super Record, Record and Chorus had both short and medium cage options. Potenza and Centaur were had a single cage option, which was essentially a medium cage. All shifters, both Ultra-Shift and Power-Shift, were indexed, and there were no triple shifters available. |

Minor correction to the above: Potenza came in both short and medium cage. Its cages were compatible with Chorus. In fact Potenza and Chorus look very similar, but Chorus has the stronger spring in the RD to accommodate Ultrashift Ergos.
Centaur 11 is a weird group all by itself. Why they didn't make it compatible or use Potenza parts confuses me. Using newer cranksets with lower gearing may not officially work because after 11speed HO (~2018), Campy moved over to a 44.5mm chainline for all 2x cranks. Also, the price of the new 45/29 SR wireless crank is the price of a new groupset. |

as I said above, give it a try.. you may be surprised.. don't get wrapped around the axle with all the talk about tooth difference here or there, wrap, etc.. again, I don't know if Campy is as conservative as Shimano on these things, but..
to be fair, I've never tried this with Campy, so it may not work at all.. but as an example, I have my new to me Anderson with a Force 11sp medium cage RD on it that came with an 11-32 cassette.. since I have my Ultegra bike set up with an 11-36, I figured I'd throw the wheel on and see what happened.. from a quick spin up and down my street, seemed to be just fine.. the cage length will certainly be a factor though, so if you have a short cage, you may be out of luck.. not saying any of these will shift with the precision of the 11-32, but will they shift fine is the question.. just do a some very easy test shifting on the workstand the first few rotations..

FYI: I'm running an Athena triple long cage rear D with Shimano 11-36t cassette, pre 2015 11 speed campy, Works. Might be able to go to a 38, but I don't need that (yet!). Cog-pulley clearance is OK, and chain wrap on big-big and small-small won't make you gag.

The crankset I like is White Industries VBC crankset. Yes, it uses a square taper bb, but there are numerous ring options from 52/36 all the way down to 38/24...Good Luck! |

If you have a braze-on hanger, and are considering smaller chainrings, make sure you can adjust the FDER low enough to reach. Please let us know what you choose and how well it works.

Options for your consideration:
Campy 11 with 46/30 chain rings and 11-34 cassette Campy 11 with 46/30 chainrings and 11-40 cassette and Deore RD |

Can you share a link to the shiftmate or whatever device you're using for this?

The old math still applies: 1 tooth in the back is 3 teeth in the front.
If you're looking for lower gearing, a bigger cassette is the best option. Having said that, all that'll happen is you end up pedaling with the same force, just going slower doing it. AMHIK M |

A bigger cassette in the back works only up to a point, because most road derailleurs will have a maximum sprocket size (and Campagnolo road derailleurs typically have a more limited maximum size than the S groups). Another disadvantage of larger cassettes is that they require a derailleur with a larger capacity (i.e. longer cage), whereas reducing chainring size generally doesn't require the derailleur capacity to increase. It should also be noted that larger cassette also usually means bigger jumps between gear sizes. Last edited by Mark McM; 04-29-2024 at 12:31 PM. |
