F-Surface Plus technology was created so you can convert the same watts into higher speeds. This technology is incorporated into our Noah and Dean models. It is the application of a textured surface (similar to grooves in a golf ball) in strategic locations for decreased wind drag. What these grooves do is create a tiny turbulence which causes the main flow of air to better follow the shape of the tube. With a smooth air travel around the frame, you’ll expertly cut through wind. The stronger the wind, the more you will feel this technology working for you.
