New US maker Boa (might just be new to me), has brought out two longboard wheels, which interestingly have the same core hole system as the Orangatang Kegel, meaning that they can be used as a direct replacement, with no change of pully or belt, with Boosted V2 boards.
The wheels, both 83a, are the Constrictor at 100mm and the Hatchling at 90mm.
UPDATE (7/4/18): Ordered some Constrictors and will write a review when they arrive.
