The Abec11 75mm BigZigs are some of the best downhill racing, carving, and grip oriented wheels available today. They were the wheel of choice for downhill racing between 2007 and 2012. This wheel has big flexible lips and a small core so there is lots of absorption for rough roads, especially in the softer durometers like 77a. This wheel has a ton of grip, and lots of roll speed and you can rely on it to be extremely durable and fast for your transportation, carving, or grip oriented downhill board. A big solid urethane Reflex formula wheel with a perfect aspect ratio. The highest level of traction and faster top end make a great downhill and GS wheel. Also great for carving and cruising on larger boards. Extremely smooth, even on rough surfaces. It rolls over everything in its path. Diameter: 75 mm. Durometer: 78A Core Placement: Offset.
