EPS rear derailleur and 11-29 cassette

Hi,

I'm almost at a point of switching my Record mechanical for a Record EPS V3.

I've been running a 52/36 with a 11-27 for some years now but I'm getting old, and starting to think about adding 2 rear cogs at the largest sprocket.

Planned to go the 11-29 route but came across a Campag tech manual stating that it won't work with a rear EPS derailleur. Only 11-27 or 12-29 will do.

I very much like the added speed of a 52/11 combo instead of a 52/12, but I would certainly welcome more 2 cogs at the rear end with my 36 front chainring.

Does anyone here had a try with a rear EPS and an 11-29 cassette?

Thanks!

    I noted the same guidance from the technical literature.

    Installed Record EPS on a bike previously running Super Record mechanical (2012 vintage) primarily because I broke a front shifter and was hacked off at a crazy replacement cost for a single front lever. Zero issues with 11-25, 12-27 or 11-29 cassettes running on the various wheelsets I swap around. I am running a 52-36 front chainring combination with TA chainrings in place of the Campag OEM but I don't think that alters the rear cassette clearance one way or another.

    My conclusion EPS is brilliant, never a shift wrong from installation onwards.

    If you can afford it - go for it!

    After all as I said to the wife - "What's an extra couple of hundred quid .........."

    :D:D
  • I have Record or SR EPS on all but a couple of my road bikes. I've used all the cassette combinations you've listed with 53/39 and 52/36 up front and no problems whatsoever. Just make sure the chain is the correct length for your setup.

    Different set up but the same advisory from Campagnolo. The maximum ratio is 16 teeth, so 11/27, or 12/28 (29 at a push, no 28 available). However, I fitted Athena 50/34 to 11/29. It worked but there was a lot of chain slack if I inadvertently crossed the chain to 34/11.
    The above may be fact, or fiction, I may be serious, I may be jesting.
    I am not sure. You have no chance.
