Product Information

Full details

The Park Tool HCW-5 is a professional-grade, double-ended spanner designed for bicycle mechanics and enthusiasts tasked with adjusting cup-and-cone bottom bracket lockrings. Its primary benefit lies in its dual-sided design, which offers two distinct hook configurations for secure engagement on notched lockrings; however, users should be aware that this tool is strictly for bottom bracket lockrings and is not compatible with fixed gear lockrings.

FAQs

Can I use the HCW-5 for fixed gear lockrings?

No, the HCW-5 is specifically designed for cup-and-cone bottom bracket lockrings. For fixed gear lockrings, use the Park Tool HCW-17.

What is the maximum diameter this tool fits?

The HCW-5 is designed to fit lockrings with a maximum outside diameter of 46mm.

Does this tool work on cartridge bottom brackets?

No, this tool is intended for cup-and-cone style lockrings, not the internal splines found on modern cartridge bottom brackets.

How do I maintain the tool's finish?

Simply wipe it clean with a rag after use. Its nickel plating is naturally resistant to rust, but avoiding moisture will keep it in peak condition.

Why are there two different hooks on the tool?

The two sides offer versatility for different styles of lockrings; one side uses a single hook for general notched rings, while the other provides a 3-notch grip for better leverage.

Troubleshooting

Tool slips out of the lockring notches

Ensure the lockring is clean of debris and that you are using the correct end of the spanner for your specific lockring design.

Lockring is stuck and will not budge

Apply a high-quality penetrating oil to the lockring threads and allow it to sit for 15 minutes before attempting to loosen again.

Pros and Cons

Pros

  • Versatile dual-head configuration
  • Professional-grade durability
  • Excellent engagement for notched lockrings
  • Corrosion-resistant finish

Cons

  • Not compatible with fixed gear lockrings
  • Limited to specific diameter ranges (40mm-46mm)
  • Single-purpose tool for specific bottom brackets

Setup, Compatibility & Care

The HCW-5 requires no assembly; it is ready to use immediately. It is compatible with cup-and-cone bottom bracket lockrings that fall within the 40mm to 46mm diameter range. To care for the tool, wipe it down with a clean, dry rag after use to remove grease and debris. While nickel-plated, keeping the tool in a dry environment will extend its life. Do not use the tool as a hammer or pry bar, as this can deform the delicate hook geometry required for precision engagement.
