The ORBEA Upper Bearing 1 1/8" + Ring ACROS MTB is a high-quality headset bearing assembly designed to keep your mountain bike steering smooth, precise, and reliable. Positioned in the upper part of the headset, this bearing works together with the lower bearing to ensure accurate control and stable handling on rough trails, technical descents, and everyday rides. Compatible with 1 1/8" steerer tubes and ACROS-style headset systems, it is an ideal replacement part when refreshing a worn-out headset or completing a frame build that uses integrated or semi-integrated bearings.
Using a dedicated upper bearing and ring helps maintain correct preload, reduce play in the front end, and extend the life of your headset and fork. Quality bearings can significantly improve steering feel, reduce creaking, and protect your frame from damage caused by excessive movement or contamination. This ORBEA component is engineered to meet the demands of modern MTB riding, offering durability and consistent performance in wet, muddy, or dusty conditions. It is a smart upgrade or service part for riders who want dependable, low-maintenance steering performance from their mountain bike.
