One weighs 2 grams while the other is 12 grams. That allowed designers to add a pair of internal 8-gram titanium weights behind the hitting area to improve ball speed, and another 8-gram titanium weight in the back of the head to boost the moment of inertia and enhance stability.Ĭomplimenting those internal weights are a pair of external adjustable sole weights. The T-shaped titanium chassis is also 7 grams lighter. To make that possible, 40 percent of the 460cc RadSpeed’s head is carbon fiber, with the carbon-fiber crown and side pieces being 6 grams lighter than the components used in last season’s SpeedZone driver. “Rad” refers to radial weighting, the positioning of more weight in both the front and rear portions of the head, to get the best benefits possible.

Moving the center of gravity back in the head can make a driver more forgiving, but it also can add dynamic loft and create excessive spin, robbing distance.Ĭobra designers know these things, and with the release of the new RadSpeed family of drivers, they think they have created three drivers with technologies that can provide the ideal centers of gravity to give golfers more ball speed and better performance without making sacrifices. For example, when the center of gravity is shifted forward, it can improve ball speed and lower spin but typically sacrifices stability and forgiveness. Most of the time, those tradeoffs relate to the center of gravity location.
