The 2021 Flightline One 27.5 model features a brand new X6 series alloy frame design with internal cable routing and an HL suspension fork with 80mm of travel to smooth out all the bumps. The FL One 27.5 model features alloy double-wall rims fitted with a Shimano cassette rear hub, and 2.2" wide tires with a multi-surface tread pattern. For 2021, we have switched to 27.5" wheels as the main wheel size on the FL One models. Following an undeniable trend towards taller and faster rolling wheels than the 26" size, The FL One 27.5 platform is ideally suited for all-around riding and an introduction to fire-roads and easy MTB trails.
