It depends on what you want. The Ruby I tested was post-geometry change (when Spesh introduced the Amira, they retooled the geometry of the Ruby into a "plush" road bike), 51cm (I'm somewhere between a 51 and 54). The shop I tested it in was located in a busy area and it was my first experience with SRAM, so it was really hard to judge the bike properly. Smooth ride, but not quite as much get-up-and-go as I want in a road bike right now.
