There have been on-going subtle variations. I tend to focus on the 58 cm Atlantis since that's what I ride. In the current chart, the gray one with the old geos shows chainstays for a 58 cm Atlantis at 45.5 cm, which is what my '03 has. But in the May '17 chart, the clock in at 47 cm. I believe these would have been Waterford. Now they're up to 53 cm. So at least 3 variations.
There could be similar slight differences on other models. Evolution happens. dougP On Sunday, May 27, 2018 at 5:15:01 AM UTC-7, Bob Lovejoy wrote: > > I do think there are are typos and/or oddities in the geometry charts, > though, who knows, maybe with certain center pull brakes 55mm is possible. > I think you are certainly right about the Tektro sidepulls though.
