【Material】
Made of high-hardness carbon steel and treated with a hardened heat-treatment process, increasing overall hardness by approximately 10%. Strong, durable, and resistant to deformation with excellent load-bearing performance.

【Features】
Precision-cut spline design ensures an accurate fit with threaded freewheels, allowing fast removal without damaging the freewheel. The upgraded slot structure improves grip and stability, preventing slipping during use.

【Design】
Optimized spline geometry allows the tool to fully and precisely engage the freewheel. The widened wrench interface provides better leverage, reduces slippage, and makes removal easier and more efficient.

【Application】
Designed for installing and removing threaded (screw-on) freewheels. Ideal for routine bicycle maintenance and repair tasks.

【Usage】
Works with a 24mm wrench to install or remove the threaded freewheel from the hub. Simple operation with high efficiency.
