This Fold-Up Hex Wrench Set combines seven common hex wrenches into one convenient fold-up tool, eliminating the need for a jumble of loose tools and allowing you to adjust most smaller hex fasteners typically found on modern bikes including seat posts, handlebars, brakes, and derailleurs. The wrenches are made from heat-treated industrial tool steel for long life, with chamfered tips for a perfect fit. Its multi-position composite handle is comfortable, lightweight, slip-resistant, and 40% stronger than steel handles.
