Yes, 23" (58.5cm) seat tube. But what I didn't count on is the short, less than 5" (13.5cm) head tube.The short story is that I was looking for a clean, feminine color, european mixte that could fit my non-riding wife (in another attempt to get her back on 2 wheels ). But having failed in the past, this effort had to have an alternative plan -- for me! So, presto chango = old man's mixte. But new to upright riding, so having component/positioning debate. edit: i mentioned my desires in this Forum last summer, and a Chicago area member had such a bike with a few things missing.
