My saddle is between 72-72.5 and I'm on a 56 Ram and 57 Bleriot. I also once owned a 58cm Ram as the size recommended by Grant and it fit the same with a shorter stem, handled well, but frankly I traded downsize because I didn't like the less than a fistful of post and slammed stem look myself. I think I could have easily gone with a 55 Bleriot as well as I like a short top tube with drops. I test rode a 54.5 Atlantis and it fit great as well.
I would recommend you go with the 56cm if you want swept back bars. I am actually surprised by the smaller recommendation, If you talk to Grant and say what bars you are using, and that you like less post showing, I think he will say the 56cm. 57 Bleriot (650b) with 72.5cm Saddle pictured below, since it has a geometry close to the AHH: <https://lh3.googleusercontent.com/-rDd5SsKpw8I/V60nAmVK5CI/AAAAAAAAAYQ/c0JX_WYIyHY5ySNW8W8YsTLzfR42p9lKQCLcB/s1600/Side%2Bview.jpg> <https://lh3.googleusercontent.com/-rDd5SsKpw8I/V60nAmVK5CI/AAAAAAAAAYQ/c0JX_WYIyHY5ySNW8W8YsTLzfR42p9lKQCLcB/s1600/Side%2Bview.jpg> <https://lh3.googleusercontent.com/-rDd5SsKpw8I/V60nAmVK5CI/AAAAAAAAAYQ/c0JX_WYIyHY5ySNW8W8YsTLzfR42p9lKQCLcB/s1600/Side%2Bview.jpg> -Dave J On Wednesday, August 10, 2016 at 11:02:07 PM UTC-4, blakcloud wrote: > > Yes, I have contacted Riv on this but I am leery of their suggestion as it > puts me on a bike that is smaller than I have ridden and this information > contradicts their own charts on the website. > > 81 cm PBH > 71 cm Saddle height > > The chart on this page <http://www.rivbike.com/kb_results.asp?ID=41> > would suggest a 55 or 56 (for 650 wheelset), yet I was told a 54 cm would > fit better.
