xxx The 109% refers to the crotch-to-floor distance. It was generated by testing racing cyclists several years ago. Many people now recommend, for sport cyclists anyway, that the seat hight be set closed to 105%. Another way to set the seat hight is to pedal backwards while someone holds your bike upright. Set the seat hight just low enough so that your hips do not rock up and down while you're pedaling. -- Kenton Lee Bell Labs - WB ihnp4!wbscc!kfl or ihnp4!hoxna!kfl
