DK Flux 20" Complete BMX Bike - Black


NEW MODEL FOR 2021. Long, stable, and strong. The all-new Flux is built with mid-school geometry for your return to the trails.

Brand new to the DK lineup, the 2021 DK Flux 20” was created for the purest form of bicycle motocross: Dirt. Don’t get us wrong, the Flux will handle the skatepark or street with no issues, but with a stretched out 21.25” top tube, super stable geometry and a longer rear end, this thing is built for speed and stability at any altitude. A matte-black finish and camo accents (including a throw-back cross bar pad) gives it an earthy vibe the mid-school will embrace. All-chromoly construction of the frame, fork, bars and cranks are built to last and ready to thrash. Sealed bearings for no fuss maintenance and 20 X 2.20 XLR8 110 PSI tires are ready to roast in the bowls or at the jumps. Chain stay mounted brakes and 28/10 gearing are details the trails crew will appreciate.
