User manual BONTRAGER RACE XXX LITE HANDLEBAR

[. . . ] Fatigue refers to a low-stress force that, when repeated over a large number of cycles, can cause a material to fail or break. The length of the life of a part varies according to its design, materials, use, and maintenance. Although lighter parts may, in some cases, have a longer life than heavier ones, it should be expected that light weight, high performance parts require better care and more frequent inspections. Regularly inspect your handlebar for signs of fatigue stress: dents, cracks, scratches, deformation, or discoloration. [. . . ] Do not attach bar-ends that use an internal, expanding clamp mechanism. Bar-ends that attach to the outside of the handlebar must use a clamp mechanism that is designed with the clamp slot radial to the clamp center, with the bolt perpendicular to the slot and as close to the handlebar as possible (Figure 3). The clamp only needs to be tight enough to prevent rotation on the handlebar. Overtightening can crush or damage the handlebar. Figure 3 Bar-end bolt perpendicular to hole radius 2 Adjust your handlebar for comfort Handlebar position- the angle, width, and height of the handlebar- is largely a matter of personal preference blending comfort, efficiency, and balance. Your hands should be comfortable, and able to easily operate all controls. If your hands, arms, or shoulders are uncomfortable or numb you may need to adjust the handlebar or select components more suitable to your personal needs; consult your dealer. Cutting the bar could remove critical carbon layers and weaken the handlebar. To adjust the angle of the handlebar 1. Loosen the handlebar clamp bolt(s) on the stem just enough that the handlebar can be rotated in the stem. Position the handlebar to the desired angle, making sure they are centered in the stem. Tighten as in Inspect your handlebar regularly. To change the handlebar height with a quill stem Adjusting the handlebar height on a direct-connect stem affects the headset bearing adjustment. This procedure requires special tools and training so this should only be done by your dealer. Tap the top of the stem expander bolt, with a wood or plastic-faced mallet, to loosen the stem wedge. This line must be hidden inside the bike frame Figure 4 Minimum insertion mark on stem quill 3. Adjust the handlebar to the desired height, but with the minimum insertion line inside the frame (Figure 4). A minimum of 23/4 inches (70mm) of the stem quill must always remain in the frame. Tighten as in Inspect your handlebar regularly. WARNING Never ride your bicycle with a quill stem raised above the minimum insertion mark. A quill stem that is positioned too high can damage the bike and can cause you to lose control and fall. Make sure the minimum insertion mark (Figure 4) is inside the frame.
