From Bicycle Magazine (May 2007): The R-660 has character. It feels responsive under power, rides comfortably and its handling is razor sharp. Corner turn-in response is instantaneous. The R-660 slices and dices; in you want to change your line midturn it’s plenty willing. Handling is consistent, not twitchy ad holds a line at high speed. With its standard-sized chainrings and zesty ride, the R-660 has the heart of a racer.
