I recently made a 'WTB' post looking for a 58cm Atlantis or Saluki. Thank you to everyone who responded (minus the infamous Gran who reached out with detailed photos of a butterscotch Saluki and a story about how he needed to make room for a custom Chapman).
I connected with a non-RBW list person and ended up with a 56cm Atlantis. After reviewing older geometry sheets with suggested PBH ranges I thought the 56cm might be a good fit if I used wider tires. After a few rides I realized the 56cm was a bit small, and then I had the chance to buy a 58cm Atlantis. I followed through and now the 56cm Atlantis needs a new home.
The frame is in very good condition with only minor cosmetic blemishes that could be addressed with a little touch up paint. I purchased the bike from the original owner who bought the frame in 2000 from a shop in Maryland.
