Rotatable footplate integrated with bearing assembly imbedded in a single-board sport board

A rotational footplate assembly for a sports board, said rotational footplate assembly comprising:

• a hollow member comprising a cylindrically-shaped interior wall, said cylindrically-shaped interior wall comprising an interior race around an interior circumference of said cylindrically-shaped interior wall, said hollow member at least partially housing within the interior circumference of said cylindrically-shaped interior wall, a shaft and a ball-bearing assembly, said hollow member at least partially imbedded below a top board surface of said sports board;
• said shaft comprising an exterior race, said shaft underlying an integrated footplate;
• and
• said ball-bearing assembly comprising a cylindrically-shaped device that houses a plurality of ball bearings, at least some portion of said ball-bearing assembly positioned between said interior race of said hollow member and said exterior race of said shaft, said ball-bearing assembly presenting at least some of said plurality of ball bearings for rotational contact with said interior race of said hollow member, said ball-bearing assembly presenting at least some of said plurality of ball bearings for rotational contact with said exterior race of said shaft, said hollow member accommodating freely-rotatable movement of said footplate according to freely-rotatable contact of at least some of said plurality of ball bearings with said exterior race of said shaft and further according to freely-rotatable contact of at least some of said plurality of ball bearings with said interior race of said hollow member.
