Ladies only? Not the Flightline One ST...One of Haro's most popular models, the FL One also comes in a step-thru frame (all genders welcome). While it is true the majority of these are purchased by women, men with difficulty lifting their leg over a traditional frame may want to jump on an ST. The Flightline One ST features an all new 6000 series alloy frame with an internal head tube mounted to a Haro suspension fork with 80mm of travel to smooth out all the bumps. The FL One ST is available in 26" wheel size only and is fitted with alloy double wall rims, a Shimano rear cassette hub, and 2.2" wide tires with multi surface tread-pattern. The FL 26 ST is ideally suited for all-around riding and an introduction to fire-roads and easy MTB trails.
