VTC Solid Coverstock
Versatile Traction Control (VTC) was formulated with durability and consistent performance in mind specifically for the HP1 and HP2 lines. This formula delivers outstanding performance while providing control and versatility without being overly aggressive. So, if stability and control is what you are after, look no further.
Hustle Core
When the original Hustle Core was created there was one goal in mind, more of an overall performance type motion in our entry level price point while providing control and stability. It is safe to say we exceeded even our expectations with this medium RG, medium differential core design. In fact, back in 2017, the Hustle INK was used to record the 34th sanctioned 900 in USBC history, thus solidifying the Hustle Core in the record books forever.
