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 axle and truck do these fit?
56mm wheels fit most standard skateboard setups. They pair well with 8.0" to 8.5" decks and mid-height trucks. Riser pads are recommended if you run larger wheels to prevent wheel bite.
