FR 4D 255mm 84 165 Flat Inline Frames

FR 4D 255mm 84 165 Flat Inline Frames. The FR 4D 255mm frames are ideal for those who want a strong freeride 4-wheel frame with 84mm wheels. The FR 4D Flat frames are compatible with almost all FR, Micro, and Seba inline skate boots, as well as many Rollerblade inline skate boots (including the Rollerblade Twister models).

The frames have a flat setup (all four wheels touch the ground simultaneously).
