KHE BLACK JACK DISC AL 20 Inch
The KHE BLACK JACK DISC AL is the ideal BMX for pump tracks, park, and street – lightweight, stable, and modernly equipped.
With its lightweight aluminum frame and a top tube length of 20.4 inches, the bike offers perfect stability and agility, with an extremely low weight of only 10 kg. The frame is matte black and is complemented by a robust HiTen fork with 3D dropouts.
A real highlight is the disc brakes front and rear, providing exceptional braking power. The peg-compatible disc hub at the rear with a 14 mm axle and industrial bearings allows for the installation of pegs. Aluminum double-wall rims and KHE MVP 2.125 inch tires with a brown tread and gray sidewalls ensure optimal grip and a cool design.
Thanks to the innovative KHE Affix Rotor System, 360° handlebar rotations are easily possible. The setup is completed by a forged 3-piece aluminum crank (165 mm) and a robust 38T steel chainring for optimal power transmission.
With its clever equipment and modern look, the BLACK JACK AL is one of the most versatile and lightest BMX bikes in its class.
