Ladies only? Not the Flightline One ST...One of Haro's most popular models, the FL One 27.5 now also comes in a step-thru frame (all genders welcome). While it is true the majority of these are purchased by women, men needing an easy-to-step-over frame may want to jump on an ST model. The Flightline One 27.5 ST features a newly re-designed X6 series alloy frame with internal cable routing and a HL suspension fork with 80mm of travel to smooth out all the bumps. The FL One ST is now available in 27.5" wheels only (in two frame sizes) and features alloy double wall rims, a Shimano rear cassette hub, and 2.2" wide tires with a multi surface tread-pattern. The FL One 27.5 ST is ideally suited for all-around riding and an introduction to fire-roads and easy MTB trails.
