The Problem Solvers Holy Driver is a durable chromoly tool used for holding and turning spoke nipples when building wheels and fixing them. You can use it manually, spinning it in your fingers to quickly fasten nipples. And, you can use it in a power drill for even faster wheel work. The tool tip fits into the slot in the top of the nipple and holds securely. Plus, the length is adjustable so it's great for use on standard and deep-profile rims.
Compatible with rims up to 45mm deep
