The all-new TSI Wheels come 120mm by 30mm and feature a fast and smooth 88A urethane rating! To be specific, the core is 24mm wide, and the urethane is 30mm wide. This gives the wheel a larger balance point for manuals, fakies (going backwards), and higher stability in general. However, this will not fit with every deck, please reach out to us if you're unsure. They are also sold individually, so the price is for one wheel. Make sure you select the quantity of 2 if you're looking to purchase a pair. All TSI product are made in the US and are backed by some of the best riders in the world. Pair these wheels with one of their decks, and who knows what tricks you'll learn!
