Park Tool Crank Bolt Wrench CCW-5

The CCW-5 is specifically engineered for crank bolts that require a 14mm socket or an 8mm hex wrench, which covers a wide range of standard bicycle cranksets.

The primary advantage is convenience and reduced clutter. By combining the 14mm socket and 8mm hex into one handle, you eliminate the need to swap tools mid-job, making your maintenance workflow faster and more organized.

Yes, the handle is designed with ergonomics and leverage in mind. Its length is optimized to provide the necessary torque to break loose tight crank bolts without requiring excessive physical strain.

While it is primarily intended for crankset maintenance, the 8mm hex and 14mm socket are standard sizes. You may find it useful for other components on your bike that utilize these specific fastener sizes, though it is optimized specifically for crank bolt access.

The CCW-5 is designed for standard crank bolts. If your crankset uses a self-extracting system, you may need a different specialized tool, as those systems often require a specific cap-removal tool rather than a standard socket or hex wrench.
