The 76mm x 59mm Hot Spot is the wheel of choice for the World's Fastest Man on Urethane – Mischo Erban, holder of the Official IGSA Downhill Speed Record of 80.83 mph (130.08 kph). Molded around our advanced Mini-EC hub, it's quite possibly the fastest all-around wheel ever developed for DH and GS racing. 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. Put everything together in the 76mm Hot Spot and you get a big, wide wheel with superior traction and roll; smooth, predictable handling; and the quickness of a smaller wheel. Choose Defcon formula for explosive speed and rebound with smooth, predictable grip-to-slip.
