The brand Bones is like the Holy Grail in bearings. All the brand's bearings are high quality bearings. The Bones bearings models are, ordered from high to highest quality: Bones Reds, Bones Super Reds, Bones Swiss and Bones Swiss Ceramics. All these models are a quality label on itself and that's why an ABEC indication is not applicable. (ABEC is an industrial standard to indicate the rate of roundness of the little balls in a bearing, but other things are important too for the overall quality of a bearing.)
The Bones Super Reds bearings are the excellent choice for who wants high quality bearings for a very reasonable price.
There exist some flavours in these Bones Super Reds bearings (depending on their intended use: for inline skates or skateboarding). We offer the Superior Grade Steel variation of the Super Reds bearings, that is suited for rollerblades. The steel of outer and inner rings has excellent skate properties for frictionlessness and resistance against torsion.
