A bike they can grow with—Diamondback's Line 24 is a junior version of their do-anything hardtail. Equipped to handle the abuse of real mountain bike trails and the bumps and bruises that come from daily use around the neighborhood. It’s made from the same 6061 aluminum alloy as their full-size bikes so it’s practically indestructible. An SR Suntour fork performs like the big guys’ bikes, giving your ripper-to-be 80mm of front suspension travel. The 24-inch wheels are stiff, stable, and shod with aggressive 2.35-inch wide Kenda tires: perfect for tearing up the woods. Powerful Tektro Aries disc brakes and a wide-range SRAM 1×8-speed drivetrain are real performance features, reinforcing that the Line 24 is a legit mountain bike—only smaller.
