Orangatang 75mm In Heat 83A Purple Wheels
Offset design with hard sharp edges for grip; thick lips for maintaining speed and rippled inner walls for progressive energy return through turns and when pumping.
Designed to maintain grip, when desired they can be slid very predictably and smoothly to shed speed. These wheels will not slide right out of the box because of their grippy sharp edges, but repeated sliding will wear down the sharp lips and allow for smoother slides.
For a more slide oriented 75mm wheel have a look at the Orangatang Durian Freeride wheels.
The In Heats are a popular wheel for speedboarding in high speed grip and rough road courses due to their size and wide contact patch.
