In-line skate wheels

An in-line skate wheel, comprising:

• a radially symmetrical body, said body defined in cross section by:
• an axial bore surface,
• a first convex arcuate perimeter surface having a constant radius subsuming less than a 180 degree angle and having a first edge and a second edge wherein said first arcuate surface is radially disposed concentric to said axial bore,
• at least one first convex transitional arcuate surface having a constant radius greater than said radius of said first arcuate perimeter surface and tangentially connecting to said perimeter surface at said first edge and radially disposed to said axial bore,
• at least one second convex transitional arcuate surface having a constant radius greater than said radius of said first arcuate perimeter surface radius, said second convex transitional arcuate surface tangentially connecting to said perimeter surface at said second edge and radially symmetrically disposed relative to said axial bore,
• a pair of spaced apart parallel sidewalls normal to said axial bore and each connecting to one of said first or second transitional arcuate surfaces to said axial bore surface and radially symmetrically disposed relative to said axial bore.
