【Rust-Resistant Aluminum Alloy】Made of high-quality aluminum alloy, this anodized design offers a smooth, corrosion-resistant, and highly robust surface. Its rational structure ensures reliable load distribution in key areas, making it a dependable tool for repeated assembly and disassembly. Whether for daily maintenance at home or frequent use in the workshop, it maintains stable performance, guaranteeing safety on every outing.

【CNC Precision | Fine Threading】The center screw utilizes precision CNC machining to achieve a uniform and fine thread pitch, ensuring smooth and controlled insertion. This effectively controls the force required to prevent damage to the steerer tube or bearings from sudden jerks. Combined with high-precision aluminum alloy connectors, the overall structure is stable, minimizing vibration and movement during use. [Knurled Handle] The CNC-machined knurled handle provides a firm grip, increasing friction and ensuring a secure hold, even with wet hands or gloves. This optimizes the angle of force application and utilizes the lever principle to reduce fatigue during installation. The flat push design distributes pressure evenly and vertically, preventing bearing tilting due to angled pressure and protecting the frame from damage. [Hydrostatic Flat Pusher] Its intuitive design allows for use without complex assembly. Simply align the pressure block with the bearing, hold the handle with both hands, and apply light pressure for installation or removal. The clear positioning mechanism reduces adjustment time, and the static press-fit method eliminates impact force, reducing the risk of errors and making it easy to use, even for beginners. [Widely Used Universal Base] Compatible with common headset sizes (1", 1-1/8", 1-1/4", 1.5") and common head tube lengths, it is also compatible with standard bottom bracket shells such as BB73, BB86, BB30, BB91, BB92, and PF30, covering most mountain bike and road bike repair needs. A single tool set covers a wide range of models, reducing costs and space. It is truly effective and versatile.
