The DK Professional-X BMX Race Bike-Cruiser-Green takes the proven geometry DK is known for and gives it an upgrade for improved stiffness and speed. Built to perform straight out of the box, the Professional-X series features premium BOX components like the X5 carbon fork and 1-piece Echelon seat/post combo. The frame is built from hydro-formed 6061 aluminum for increased strength while remaining lightweight and features a tapered head tube with internal cable routing. First-rate components from DK, ProMax, Maxxis and DUO Brand complete the set-up to deliver this high-performance racing machine.

NOTE: As with any complete bike, J&R Bicycles recommends that you have a professional bicycle store build your bike. Bikes ordered through mail-order come partially assembled and need to be inspected and assembled by a bicycle mechanic. Failure to do so may void the manufacturer’s warranty. Manufacturers warranties differ for every brand. You can check the brand’s website for warranty information.
