Featuring an exclusive profile designed for the optimal balance of speed and slide. 58mm to fit all sizes of Balance frames as well as most other low profile frames on the market. The 90A hardness provides a more durable ride focused on long lasting performance.

Sold in packs of 4, but we highly recommended you ride them flat. Also works great when paired with softer wheels on the outside to reduce wheel bite and increase longevity.
