Thanks to its lower stand-over height frame and 24" wheelset, the Flightline 24 is perfect for adventurous kids who love to ride but aren't quite ready for the larger sizes yet. The FL 24 features Haro's FL3G low profile X6 alloy frame with a ton of stand-over clearance. Bumps don't stand a chance thanks to its suspension fork with 40mm of travel. The FL 24 features a new 1x7-speed drive-train with a single chainring to make it easier to switch gears.
