One of Haro's most versatile, affordable, and trusty steeds, the Flightline One 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 has tried-and-true 26" alloy double wall rims, a Shimano rear alloy hub, stainless steel spokes and 2.2" wide tires with multi-surface tread patterns ideally suited to on-road riding as well as off-road. Its 21-speed drive train has everything you need to get there and nothing you don't.
