The new Center Trac Bearing from YoYoFactory is now available; this is the LARGE size one. This yoyo bearing will really improve your play!
The Center Trac has a concave outer surface so that the string is focused towards the centre of the bearing. This result's in a much smoother and longer spinning yo-yo because the string does not rub against the side walls of the yo-yo slowing it down.
With this bearing you will be able to compile yoyo tricks which are very complicated and long.
This bearing fits any yo-yo that uses the bearing size or type C, Large Size C, measures 0.250 x 0.500 x 0.178 inches.
