The ORBEA Stem Preload Bolt and Low Cap Diem is a small but essential component designed to keep your cockpit running smooth, quiet, and secure. Mounted at the top of your headset, the preload bolt and cap work together to correctly tension the headset bearings before the stem is tightened. This helps eliminate play, reduce unwanted creaks, and maintain precise steering control, whether you are commuting, training, or riding long weekend routes. As a genuine ORBEA part, it is engineered to integrate cleanly with compatible ORBEA frames and stems, preserving the bike’s original look and performance.
This low-profile cap is ideal for riders who appreciate a sleek, modern aesthetic and want a tidy transition from stem to headset. It is particularly useful when fine-tuning stack height or refreshing a tired front end during routine maintenance. Replacing a worn or damaged preload assembly can extend the life of your headset, protect bearings from uneven wear, and restore that crisp, confident steering feel. Simple to install with standard tools, the ORBEA Stem Preload Bolt and Low Cap Diem is a smart upgrade or replacement for any detail-focused rider.
