Professional = the highest level in the sport. X = 10 years. Professional-X = ten years of progression.

DK celebrates 10 years of high performance with the all new Professional-X series of race bikes. Building on the same proven geometry thats been raced to countless UCI World titles and Olympic main events, the Professional-X frame is remastered to be stiffer, stronger, and deliver more speed straight out of the gate. The pro-level build delivers straight out of the box too. BOX Components X5 carbon fiber fork and lightweight Echelon 1-piece seat/post combo come standard. Other impressive spec includes top of the line components from DK, ProMax, Maxxis, and DUO Brand.
