3rd bike For bar hopping and guest. Largest Mixte I ever rode or seen. Seat tube (center to center): 54.6cm, Top tube (Horz.) 56.5cm.
I'm 5'11" and the seat height in the picture is set for me. Now I can understand why the girl who I bought from said it was too big for her. I normally ride a 55-56cm track frame. The bike came stock with drop bars.
These bikes are fast & comfortable when built in a minimal way and matched with a light wheelset; this is key. Don't notice a huge amount of much flex when riding hard except in the stem/bar area.
