The 63mm x 45mm Hot Spot is a small, super-agile version of our 69mm and 76mm Hot Spot shapes.  Molded around our advanced Mini-EC hub, it’s a light, quick, do-it-all wheel – ideal for general-purpose cruising, surf-skate, and Tight / Hybrid slalom.

Not too big and not too small, the Mini-EC hub preserves ample tire thickness while saving over ½-ounce per wheel, stiffening the inside edge, and super-charging inside edge rebound.

_**Available in TWO proprietary formulas, with finely-tuned durometer choices.**
