Questions & Answers

What is 97D hardness best suited for?
97D is a hard wheel, ideal for smooth concrete, skate parks, and street spots with good surfaces. Hard wheels roll faster and slide more predictably, making them the go-to for technical street skating and park sessions.

What does Conical Full shape mean?
Conical Full wheels have a wider outer lip and a full contact patch that runs across most of the wheel's width. This gives you more grip on landings, a more stable roll, and reliable lock-in when grinding ledges or rails.

What size setup do 54mm wheels suit?
54mm is a popular mid-size street wheel that pairs well with 8.0" to 8.5" decks and most standard truck heights. No riser pads are typically needed at this diameter, keeping your setup low and responsive.
