The 66mm x 49mm 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 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.

_**Now available in DEFCON™ ultra-high-rebound formula, in three finely-tuned durometer choices**  
_Thoroughbred race ‘thane • Guinness WR speed • directional slide • long-lasting grip • slow, consistent wear
