What spoke nipple sizes does the Park Tool SW-7.2 cover?

The Park Tool SW-7.2 Triple Spoke Wrench covers the three most common spoke nipple sizes in a single tool: 3.23mm, 3.30mm, and 3.45mm. Nickel-plated for long-term durability, the SW-7.2 is designed for the home mechanic who wants one spoke wrench that handles the full range of standard nipple sizes without buying multiple individual wrenches. Precisely sized openings provide a snug fit on each nipple size, reducing the risk of rounding during truing adjustments.

Wheel truing is one of the most common and satisfying home mechanic tasks, and having the right spoke wrench fit is the difference between clean adjustments and rounded nipples. The SW-7.2 keeps all three sizes on a single tool so you can identify the correct size and get to work without rummaging through a drawer of individual wrenches.
