This set includes two hubstacks, two O-rings and two Dorothy bearings, to replace the hubstacks on a single yo-yo in case the originals are lost or damaged, or if you want a different color hubstack. These bearings are the same models that come standard with hubstack yo-yos.
*This part can only be used for YoYoFactory yo-yos compatible with hubstacks.
