The Street Invaders wheels are the wheels that are pre-installed on the better inline skates of Seba and FR. As such you can deduce that it is suited for slalom, freestyle, freeride, tours. In my experience it is the most comfortable wheel in these diameters. On bumpy streets you really experience less vibrations than with other wheels. And yet it is quite fast and durable. In rainy conditions it behaves, let's say, reasonably.
