Restore the crisp, responsive feel of your bike´s steering with the genuine Fsa MR137 ACB 45x45 Steering Bearing. As a critical component within your headset, this high-quality replacement part from Full Speed Ahead (FSA) is engineered to eliminate play, roughness, and noise, bringing back the factory-fresh performance you expect from your ride. Whether you´re performing essential maintenance or upgrading a worn-out part, this bearing is the definitive choice for cyclists who demand precision and reliability.

The primary benefit of the Fsa MR137 lies in its advanced design. It is an Angular Contact Bearing (ACB), a feature that sets it apart from standard radial bearings. This sophisticated engineering allows it to handle both radial (vertical) and axial (side-to-side) loads simultaneously. For a cyclist, this translates into exceptionally smooth steering under pressure, whether you´re climbing out of the saddle, cornering at high speed, or navigating technical terrain. The ACB design ensures that forces are distributed evenly across the ball bearings, significantly reducing friction, preventing premature wear, and enhancing the overall longevity of your headset assembly.

Main Features:

Precision Angular Contact: The 45x45 degree contact angles are meticulously machined to ensure a perfect interface with compatible headset cups. This precise fit is paramount for eliminating any micro-movements or "slop" in the steering column, providing you with direct, confident control and a connected feel to the front wheel.

Engineered for Durability: Built to withstand the rigors of all cycling disciplines, from road racing to mountain biking, this bearing is a testament to robust construction. It is designed to resist contamination from dirt, water, and sweat, which are the primary causes of headset failure, ensuring consistent performance ride after ride.

Optimized for Performance: These high-performance Bearings are the heart of your headset. By replacing a gritty or indexed bearing with the Fsa MR137, you will immediately notice a significant improvement in steering fluidity. This not only enhances the riding experience but also improves safety by allowing for more precise and effortless line adjustments.

Genuine FSA Spare Part: As an authentic FSA component, the MR137 (also associated with the NO.54 headset) guarantees perfect compatibility and performance with specified FSA headsets and other systems requiring a bearing with these exact dimensions and angles. Avoid the uncertainty of generic parts and trust the brand that is synonymous with high-performance bicycle components. This specific part is your go-to solution for maintaining the integrity and performance of your FSA-equipped bicycle.
