Bottom Bracket Wrench - Cup-and-cone Lockring

The Park Tool HCW-5 is an outstanding double-ended wrench crafted to fit the lockrings on cup-and-cone bicycle bottom brackets. One end comes with a single hook, while the other end has 3 notches, which provide a better grip on the lockrings. This wrench is heat-treated and nickel-plated, ensuring it will last a lifetime. It's a must - have tool for any bicycle enthusiast or mechanic.

To use this Park Tool HCW-5, first, identify the lockring on your bicycle's cup - and - cone bottom bracket. Then, choose the appropriate end of the wrench. If the lockring has a design that suits the single hook, use that side. If it works better with the 3 - notch end, use that one. Just place the wrench onto the lockring and turn it as needed. When using, make sure to apply steady pressure to avoid slipping. For maintenance, after each use, wipe it clean with a dry cloth. You don't need to oil it often, but if it starts to feel a bit stiff, a light coating of oil can help. Keep it in a dry place to prevent rust, and it'll serve you well for a long time.
