Rubber Sharp is a Performance Tip released as part of the Hybrid Wheel System. It debuted with the release of Grand Cetus T125RS and Grand Cetus WD145RS in July 2010.


RS is a sharp tip made of rubber. RS's primary purpose is to counteract Attack customisations: the high friction of the rubber tip, along with the lack of movement due to the sharp tip make it incredibly difficult to move, and KO.

RS has similar problems to other sharp tips, and is easy to destabilise. RS also suffers from the poor stamina of rubber-based bottoms, and their tendency to wear down after extensive use.

RS also has difficulty sometimes outlasting left-spinning customisations. Against right-spin Attack customisations however, despite its poor balance and stamina, it is able to effectively neutralize them.

Use in Defense Customisation

RS can be put to use in the top-tier combination, MF-H Basalt Kerbecs 85RS.
