Bones Super Swiss 6 bearings (SS6) are fundamentally different from the famous Bones Swiss.
Super Swiss have 6, 3/16 inch balls instead of 7, 5/32 inch balls. The SS6 balls are 20% larger and roll fewer times to go the same distance. Like bigger wheels on a car, they create less rolling friction and have a higher top speed.

SS6's special design and Swiss quality materials enable it to accelerate quicker, roll faster, and resist the impact of skate trick landings better than standard designs. 20/Pack.
