A smaller bearing can in theory make a yo-yo spin faster, but due to the bearing width, small bearing yo-yos lead to a smaller gap width that defeats the long spin. This kit uses SPR technology to give a small bearing a large bearing gap while still preserving the longer spin times. Just like the large kit, except these spacers are designed for a smaller bearing. This kit comes with two SPR spacers, a pair of friction stickers, a threaded rod, a pair of nuts, and a type B bearing.
