No - it has definitely been trending slacker, and the top tube trending longer. Other models, too. I don't think that, for Rivendell, this has as much to do with following the general trend in mountain bikes though, as much as it is intended to balance things out and keep the rider centered with the ever-longer chainstays. Mainstream mountain bikes still seem to keep the chainstays as short as possible, so the slack front for them is mostly about keeping the wheel out in front as you're bombing down steep hills.
My All Rounder - predecessor to the Atlantis - has a 72.5 degree headtube. The "classic" Atlantis, which was still very much just a production version of that road/touring geometry, had for many years a 72 degree headtube. In 2016 or so, it briefly went to 71.0 (and 650b wheels). But then in 2018 it steepened back to 71.5 (and regained 700c wheels.) I guess I'm not exactly sure when it went to 70. It may have been a couple of years/versions ago. But it just got longer and gained tire clearance in this update. Maybe I just wasn't paying attention and my current enthusiasm is delayed. At any rate, I'm glad it doesn't stay static. Incremental improvements never justify upgrading for me, but cumulatively it eventually becomes a whole new bike and worth considering. ESPECIALLY if it approximates my "ideal" bike. I do enjoy the slacker headtubes of modern mountain bikes though, too. It just works better with the way I ride these days On Friday, October 18, 2024 at 8:35:22 PM UTC-6 Dan wrote: > I’m curious to know if the 2025 Atlantis has changed much from the > previous one.
