The Jet 4 Flamme Rouge (FR) wheels represent the finest clincher aero wheel technology in the world. It's built with aerodynamics that can win Kona and a weight that can put your bike below the UCI legal limit. The 2011 edition features 1K carbon aero sections (saving 30g per rim), stadium C2 outer rim, hub hardware, new rear wheel lacing pattern, and a new grease port rear hub.

Since the introduction of the C2 platform in 2008, Hed has experienced a dramatic improvement over previous designs: aero drag was reduced substantially and the use of wider tires dramatically improved cornering. Stability Control Technology (SCT) is Hed's proprietary rim profile tuning process. Each rim depth is shaped for lowest aero drag and fine-tuned to maximize stability in crosswinds.
