Based on my personal experience, the choice between the 58 and 61 frames will really come down to the desired effective distance to your handlebars for your own personal fit. I'm 5'11" and my saddle height is 79cm, which means id be at the top recommend range for the 58 or in the middle for the 61. Riv put me on a 61 which is perfect vertically, but based on where I need the brake hoods to be so in order to minimize/avoid shoulder and neck pain, I've ended up with a 7cm stem and my bars exactly 1" higher than my saddle.
If I wanted to ride with a longer stem which could have a different effect on the handling of the bike, the I would need the 58 but also a taller stem and would show more seat post and stem post to preserve the saddle height and bars relationship. If I didn't have the left shoulder pain, then I'd probably be riding an 8-9 cm stem. This is applicable to Noodle bars which have a long reach. With other drop bars or bar types such as Albatross or Moustache bars, the stem length would have to be adjusted accordingly. So, the fine points to consider when talking with Riv to choose a size should be your preferred position in terms of how upright or bent forwards you want to be, the type of bars you'll want to use and the height of the bars in relation to your saddle. Even if you have trouble measuring your PBH (I couldn't do it right until they did it), measure the distance between the top of the saddle and the center of the crank arms along the seat post on your current bike where i assume you are properly fit and use that as a guide. Last, trust their advice and if needed, send them a photo of you on your current bike so they can asses your riding position and make additional recommendations. Forget about your current preconceptions about stand-over height and trust them. They'll stand by you and giver you good advise. I have both a 61cm Atlantis and a Homer, but the 60cm Bombadil they recommended turned out to be too long for me with its longer top tube. And I'm running 50mm Marathon Supremes on the Atlantis, which make it taller than thinner tires. Vertically, however, it fits perfectly. With the 7 cm stem I have the best fit I've ever had on a road bike in my entire life. More importantly, I'm starting to ride completely pain free on most of my rides now. And of course, working on the causes of the pain with a good chiropractor. It's amazing how unbalanced we get physically over the years as we get older and hit the 5th floor! Congratulations on choosing to get an Atlantis.
