Restore the silky-smooth, responsive steering your bike was designed for with the genuine FSA ACB MR172 36x36 Steering Bearing. As a critical component of your bike´s headset, this bearing is the key to eliminating frustrating play, notchiness, or grinding noises that develop from a worn-out part. Engineered by Full Speed Ahead (FSA), a brand synonymous with high-performance cycling components, this replacement bearing is crafted to meet and exceed original equipment standards, ensuring a perfect fit and a return to flawless handling.

Experience a significant upgrade in your ride quality. The primary benefit of installing a fresh FSA MR172 bearing is the immediate improvement in steering precision. Feel more connected to the trail or road, with confident control in tight corners, on fast descents, and during technical maneuvers. Its robust construction is designed for longevity, offering exceptional resistance to contamination and the constant forces of riding. This means more time enjoying your bike and less time on the maintenance stand. By replacing a worn bearing, you not only enhance performance but also protect your frame´s head tube and fork´s steerer tube from premature wear and potential damage.

Main Features:

* Angular Contact Bearing (ACB) Design: Specifically engineered to handle both the radial and axial loads unique to a bicycle headset, ensuring optimal performance and durability.
* Precision 36° x 36° Contact Angles: The precisely machined inner and outer angles guarantee correct alignment and load distribution within compatible FSA and other brand headsets, preventing binding and ensuring fluid rotation.
* High-Precision Manufacturing: Built to exacting tolerances for a drop-in fit, providing a stable and secure interface between your fork and frame.
* Direct OEM Replacement: Designed as a direct replacement for bearings marked with MR172 or TH-872, taking the guesswork out of your repair and guaranteeing compatibility.

This FSA headset bearing is the unsung hero of your bike´s front end. Over time, the constant micro-impacts and environmental exposure to dirt and moisture can degrade your original bearings, leading to that dreaded "indexed" steering feel where the handlebar seems to click into a central position. The FSA ACB MR172 is the definitive solution. Its Angular Contact Bearing (ACB) system is superior to standard radial bearings for this application, as it is purpose-built to withstand the complex forces exerted during steering and braking. Trust in the quality and engineering of FSA, a brand with Italian roots, to bring your bike´s handling back to its peak. Before ordering, we highly recommend confirming the specifications by checking the markings on your existing bearing.
