The Wolf Tooth Pack Wrench Cinch and ISIS Spline Wrench Insert is designed for dedicated cyclists and bike mechanics who prioritize weight savings and portability during trailside repairs. This precision-machined tool allows users to maintain ISIS bottom brackets or Race Face Cinch direct mount chainrings without carrying bulky shop tools; however, it requires the separate purchase of the Wolf Tooth Pack Wrench to function effectively.

No, the Wolf Tooth Pack Wrench is sold separately. The insert is a modular component designed to be used with the wrench.
The insert is specifically designed for the Wolf Tooth Pack Wrench geometry and may not fit standard 3/8-inch or 1/2-inch drive sockets.
While it is durable enough for home use, it is optimized for portability. For high-volume daily shop use, a full-sized steel handle wrench is often more ergonomic.
No, this specific insert is designed exclusively for ISIS splined bottom brackets and Race Face Cinch chainring systems.
Use a clean shop towel to wipe away grease and dirt after each use. Avoid harsh chemical solvents that could potentially degrade the nickel plating over time.
Verify that your component is either an ISIS standard bottom bracket or a Race Face Cinch lockring; the insert is not compatible with other standards like Shimano Hollowtech II or SRAM DUB.
Ensure the insert is fully seated into the Pack Wrench housing and clear any debris from the connection points.
The Pack Wrench has a specific orientation; ensure your grip is positioned at the end of the wrench handle to maximize the available mechanical advantage.
To use the insert, simply slide it into the Wolf Tooth Pack Wrench until it locks into place. The insert is compatible with standard ISIS Drive bottom brackets and Race Face Cinch direct mount chainring systems. After use, wipe the insert with a clean, dry cloth to remove debris or grit. While the electroless nickel plating is highly durable, it is recommended to store the tool in a dry environment to prevent surface staining over long periods. Regularly inspect the splines for any metal burrs or damage before inserting into your bike's bottom bracket or chainring lockring.
