As the name implies, the DK Professional series complete bikes are designed for premier level BMX racing, right out of the gate. All Professional models are ready for the race track, box stock, with a size for every class. Created with advanced Airformed construction, the 6061 aluminum frames of the Professional series feature external Euro bottom brackets, integrated headsets, and 3D 15mm dropouts. The low profile geometry of each frame size is crafted for speed and stability. The crucial front end setup of the Professional series starts with Box carbon fiber forks with 20mm dropouts for the ultimate combination of strength and lightweight racing performance. From the sealed headset up, youll find a CNC machined top load stem clamping tight to the DK chromoly race bars, in sizes proportionate to the frame size of each model. Promax brakes provide the stopping power, with forged aluminum 2-piece cranks putting the power to the ground. The wheelset of the Professional series is where things get rolling, and Maxxis DTH tires put the rubber to the race track with minimal resistance and maximum traction. Sun Envy double wall rims are laced to DK sealed bearing hubs, for smooth spinning, straight-line speed, and lateral strength in the turns. In the front, youll find the stiff responsiveness of a 20mm thru-axle, while the rear hub is ready to snap out of the gate with a 15mm cassette featuring 120 points of engagement for instant response and transfer of power. When the race is over, flip the quick-release seat post clamp and raise the Box Echelon seat to cool down. If youre ready to take your BMX racing seriously, look no further than the DK Professional series bikes.
