The DK Professional celebrates 10 years of topping podiums and high performance with an all-new design called Professional-X. Building on the same proven geometry that’s been raced to countless UCI World titles and Olympic main events, the Professional-X is remastered to be stiffer, faster, and deliver straight out of the gate. The Professional-X frame includes a Hydroformed tube set with tear drop and hourglass bridges, 3D dropouts with 20/15/10mm axle compatibility. The low-profile geometry of each frame size is crafted for speed and stability.
