I am 5’6” with 41” X-seam and ended up getting the Bacchetta Giro A20. I considered the A26, sat on one in the shop and my feet could barely touch the ground. I think if I was doing long touring miles it would be great, even at my height. I ride in the city though, with lots of starts and stops, so the smaller front wheel lets me get my foot confidently down, as well as the height difference between the seat and bottom brackets is less than on the A26.
Not sure of your height or riding location would affect your decision, but it did for me. I’m interested in how your test rides go and what you learned. Please keep this thread updated.
