If you want a tidy bearing upgrade for the Ultima SB, the Kyosho BRG014TSB fluorine shield units are a sensible choice. They are produced to resist contamination and keep your wheels spinning true across different surfaces.
The Kyosho BRG014TSB bearings come in the 10x15x4mm size to match Ultima SB mounting points. The fluorine shield limits dust and grit entry, which helps preserve bearing life when running on grass, carpet or hardpack.
