OJ Shin Sanbongi Dolphins Wheels

The dual-durometer construction pairs a hard 101a outer urethane for speed and sliding with a softer 95a inner core. This gives you the crisp, loud slide of a street wheel while the inner core helps absorb road vibration on rougher ground.

The wheels feature a round back and a conical front, which allows you to customize your setup. You can run them with the conical side facing out for easier lock-ins on grinds, or flip them to prioritize stability and a different aesthetic.

These are primarily designed for street and all-terrain skating. The 54mm size and wide road surface provide the stability needed for technical tricks, while the dual-durometer setup makes them much more forgiving on imperfect pavement than a standard hard wheel.

Yes, because the outer contact patch is 101a, they offer the same slide performance you expect from a hard street wheel. The softer 95a core is internal, so it improves ride quality without making the wheel feel 'grippy' or sluggish during slides.

Yes, 54mm is a versatile, industry-standard size that works well for most street and park setups. It provides a good balance of speed and weight without being so large that you risk wheel bite on most standard truck heights.
