Sorry for not addressing the question I have no trouble going 18 tooth drop with Rene hearse crank & a Campy triple front derailleur. Course I am friction shifting.

I may or may not rebuild the bike to friction and silver and if I do I’ll choose components that I’ve found or that are reputed to work best while looking nicer than the fugly components on the bike now. OTOH, I may just leave the R8000 group because, ugly or not, it works superbly and I ought to have (I’ll leave parsing “ought” to later) have at least one bike with a modern drivetrain. At least you can cross chain with relative impunity, as many people responded when I asked, “How many cogs can I use with the Big? The small?" I’d thought of swapping the R8000 crank to smaller outer and inner rings, but I see that “they” offer only 50 and 46 outers and that 34 is the smallest inner. What shite. I’d like a 48/34 or perhaps a 48/32 or even a 48/30. Damned systems that lock you into the machine’s choices instead of your own; as computers do. So my original question in fact bears only on some possible future friction setup. Still, can I shift 20 t between 1X + granny chainrings if well set up and use relatively occasionally for the steepest hills?

Nothing better was ever made by anyone, and not many were as good. --Shannon On Saturday, February 14, 2026 at 10:55:45 AM UTC-8 [email protected]<mailto:[email protected]> wrote: Thanks, Steve. I’m using an Ultegra 11 sp 50/34 double and wondered if I could go as low as 32 for the inner ring. Perhaps what I’ll do is switch to a 48/32. If I go friction, I’ll center the outer ring on the cassette.

The original small chainring was a 28t, so I may - or may not - have been exceeding Shimano's spec for the FD. I don't recall if you're using 'brifters' on your Roadeo, so I should mention that the bike was setup with friction shifting.

This group includes a 50/34 double. I think of switching it to a 50 + something smaller than 34. Do any of you have a 20-tooth gap between big and small rings? What front derailleur? How does it work? I’d center the big ring so that the drivetrain is a 1X + occasional use granny. I’d use the 50 with all 11 cogs, cruising gears would be the middle 5 cogs in the big ring, and I’d use the granny only for very steep hills. Would this work? Things to be wary of? Thanks.
