Combining the power of their existing range of frames, Ground Control has come up with the ultimate frame, the Ground Control FLT 4 Frames. Using the strength of the Mega frame, the low weight of the FLT 3 frame and the wheel protection from the HD H-Block the FLT 4 uses these parts in synergy to make the ultimate GC frame to date. The FLT 4 frame comes standard with a plastic H-Block, but the aluminium HD blocks are also compatible. The bottom of the frame is trimmed, squaring off for longevity and better wheel protection. The FLT 4 frame is designed for 60mm maximum wheel size (but we tested them with 62mm wheels flat and button head UFS frame mounting bolts).
