A usual complaint from new riders trying to get into the cycling groove is feeling uncomfortably perched forward with too much weight on their wrists and having to crank their necks backwards just to be able to see in traffic. We specifically design our Explorers to remedy this. With extra long head tubes to push handlebar height up, shorter top tubes to pull handlebars closer to the saddle, 4-inch rise handlebars that sweep back at a natural hand-grasp angle and long-quilled or angle-adjustable stems that allow for a wide range of adjustment to tune handle bar height and reach perfectly for each rider.
