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). 

Wheelbase options
Size 1 = 247mm /   US 4-7 / EU 35 - 40 / UK 3-6
Size 2 = 257mm /   US 8-9 / EU 41-42 / UK 7-8
Size 3 = 270mm   US 10-13 / EU 43-47 / UK 9-12
