The Flightline One 27.5 model features an X6 series alloy frame with an internal head tube mounted to a Haro suspension fork with 80mm of travel to smooth out all the bumps. It features 27.5" wheels, which are slightly taller and faster rolling than the 26" size, made from alloy double wall rims fitted with a Shimano cassette rear hub, and 2.2" wide tires with multi surface a tread pattern. The FL 27.5" is ideally suited for all-around riding and an introduction to fire-roads and easy MTB trails.
