The G-Carbon Series poles are available in 10.4mm and 12.7mm shaft diameters. The 12.7 G-Carbon Lite provides for a stiffer (less flexible) shaft than does the 10.4mm diameter shaft.
About GOODE ski poles
Our patented pole design features thin "pencil" shafts for better balance and feel. G-Carbon composite poles are about 25-percent lighter and up to six times stronger than aluminum alloy poles, don't bend, are more durable, and have excellent feel and balance. Our poles are smaller in diameter, only 10.4 mm or 12.7mm vs. up to 18 mm and most shafts are the same diameter at the top and bottom.
Our firm, flexible shafts take advantage of the natural shock absorption properties of the carbon blend. Lightweight, firm performance, but less "kick back" for better balance, and they're easier on hands, wrists, elbow and shoulders.
And we're not just lightweight in the store, but we get even more lightweight during a long day on the slopes when compared to larger diameter poles that have more wind drag. Wind drag equals exponentially more weight the faster you ski. Lightweight poles simply perform better than heavy ones
