Thanks to its lower stand-over height frame and 20" wheelset, the Flightline 20 is perfect for adventurous youngsters who love to ride but aren't quite ready for the larger 24" or 26" wheel-sizes yet. The FL 20 features Haro's low profile X6 alloy frame with a ton of stand-over clearance. Bumps don't stand a chance thanks to its suspension fork with 35mm of travel. The FL 20 features a new 1x7-speed drive-train with a single chainring and Revo shifter to make it easier to switch gears.
