Powell - Bones Super Swiss 6
£49.98 (ex VAT £42.54)
ADD
Same as the standard Swiss bearings except Super Swiss have six larger diameter balls instead of the seven balls used in most bearings. The advantage of this design is higher speed, faster acceleration, greater strength and durability. They tend to deal with dirt alot better being more resistant to scratching which can effect the shape of the ball bearing.Heres a testomonial from George Powell'We test all these bearings with custom equipment we have made to compare the important qualities of bearings like drag and vibration at high speeds and extended roll at low and medium speeds. Then we have our team ride the bearings until the bearings "die" to see how long they will last and how they perform in actual skating environments. Some of the bearings you will see advertised or sold in shops are junk and some are pretty good, but no bearing we have ever tested has equaled the performance of Bones Swiss.'READ FOR MORE INFO www.bonesbearings.com/products/historyCheck out the bones site, there's tons of info on there about their bearings, history and cleaning methods.ABEC 7 million PleaseABEC - Stands for Annular Bearing Engineering Committee. These dudes set up a comity to rate the tolerance of bearings. Which is basically the gap between two moving parts. (we're talking hair widths and less here) As this gap is so small many factors, such as smoothness of the rolling contact surfaces, ball precision, and material quality are obsolete. So if your a machine gunner in Afghanistan on the back of a snatch land rover, this may effect you. But if your a skateboarder and are crazy about ABEC size then burn your board and buy some rollerblades.
