The adjustable grip allows you to adjust to a shorter length for a truly customized pole fit. You have -3" of customizability from the original height. Our patented pole design features thin "pencil" shafts for better balance and feel. Pure carbon composite poles are about 30-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 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 carbon. 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. Goode Pure Carbon Ski Poles
