Justin, curious to know your fit specs. Height, PBH, saddle height? I only ask because it may help you determine exactly what you may need. For example, I have a 54.5cm Toyo with 26" wheels and I am 5' 8", with an 83 PBH and a 72 cm saddle height. My Atlantis fits me well, but at times it feels just slightly on the small side. Maybe it's just a silly thought, but I often wish I could find a 56 cm 26" Atlantis for a bit better fit. I've ridden a 58cm Toyo and while I *can ride it, that size is definitely too big for me, especially with the 700 wheels.
