Park Tool Cone Wrench

Standard wrenches are typically too thick to fit between the locknut and the cone on a bicycle hub. This cone wrench is specifically machined to be thin enough to slide into those tight spaces while providing the leverage needed for precise bearing adjustments.

No, this is a size-specific tool. You must measure the width of your hub's adjusting cone to ensure it is exactly 19mm before purchasing, as using the wrong size will likely damage the flats on your cone.

Yes, the industrial phosphate finish is designed to be corrosion-resistant, which helps protect the steel from rust in damp shop environments or humid storage conditions.

The Y-head design reinforces the wrench at the point of highest stress. This added material prevents the tool from flexing or spreading under the heavy torque required to loosen or tighten stubborn hub cones.

This tool is purpose-built for hub assembly and disassembly. While it is a high-quality steel wrench, its thin profile makes it unsuitable for general-purpose tasks where you might need to apply significant force to standard-sized nuts and bolts.
