Hi Lester You are confusing me. You say you have a 55cm Cheviot with e 57.5cm ETT. That's not what the current Geo-chart <https://www.rivbike.com/pages/geometry> says. Do you have a Cheviot that does not match the geo-chart? Does your post have a typo? According to the numbers on Rivbike.com, a 53cm MIT-Atlantis has a 2cm SHORTER effective top tube than a 55cm Cheviot. In addition to that, a 53cm MIT-Atlantis has a 0.5 degree more laid back seat tube angle, which means that you will move the saddle ~5mm farther forward on your Atlantis than you did on your Cheviot. That's 2.5cm (a full inch) shorter cockpit, so you should be good to go with drops.
