DK Professional-X BMX Race Frame Pro XXL 21.5"TT

The DK Professional-X BMX Race frame in the Pro-XXL version is based on a geometry that has proven successful on international BMX race tracks for years. For the Professional-X update, the frame was specifically stiffened to enable an even more direct power transfer during the start and acceleration phases.
The Pro-XXL size offers more reach and a longer wheelbase, which becomes particularly noticeable at high speeds in the form of additional stability and control. The hydroformed 6000-series aluminum tubing combines low weight with high structural stability. Details such as the internal brake cable routing, the trapezoidal seat tube in the bottom bracket area, and the variable 3D dropouts with integrated chain tensioners make the frame a consistent choice for ambitious BMX racing.
