Thanks for the kind words! Yes, it's a nice bike and takes 38s for sure. (Shown with tires that measure 37mm actual and there's still some room).
Yes, Reed Idlewild was the one with ultrasonic tube measurements. His sheet has two Rams with oversize ~8/5/8 top tubes (which matches the info above), and a Roadeo with oversize ~7/5/7. For what it's worth, when I asked Riv about tubing, Will told me "the Roadini is similar to a Ram, and the Roadeo is lighter than either". -Arvi On Monday, February 16, 2026 at 8:50:40 AM UTC-8 iamkeith wrote: I take that back. I must be thinking about a different bike. Here's historical info on ram tubing: https://web.archive.org/web/20070513053057/http://rivbike.com/webalog/frames/50074.html BTW, it was Reed [Idlewide?] that was measuring tubes. Look for threads titled "unmeeting", from around 2008.

If that's true, the Roadini will not only be heavier, but noticably stiffer. If you're sensitive to a stiff bike, I can see you preferring one or the other on that basis alone. (I dislike stiff frames. Others prefer them. Most don't care.) Just a thought. --Shannon That's a good point. I have this vague recollection that the 58cm was the cutoff pount after which some of the tubing became more stout, too. I could be wrong, but I have a 60 Ram, next size up, so it stuck with me for some reason. It might have been a number of years back when the someone in this group was measuring members' bikes and creating a spreadsheet. *Also, that's a stunning bike. I'd have to actively hate it before I'd sell something that pretty. On Tuesday, February 10, 2026 at 7:17:28 PM UTC-8 Arvi wrote: Hello. I'm tentatively considering whether my new to me Rambouillet (blue, size 58) has a long term home in my stable. It's a great bike, but I already have a perfect-for-me 700x30 road bike and a 650x42 randonneur, and the Ram overlaps with these. A 54 lugged roadini would fit me and be a little more different, with bigger tires and slacker angles. Let me know if a trade (with $ to balance as needed) interests anyone. I'm in Oakland, CA. (I would not be interested in other, stouter-tubed Riv models or non Rivs, thanks!)
