Park Tool SW-9 Spoke Wrench

The SW-9 is a dual-ended tool that fits two common spoke nipple sizes: 0.127-inch (3.23mm), which corresponds to the Park Tool SW-0, and 0.136-inch (3.45mm), which corresponds to the SW-2.

The primary advantage is its slim, double-ended profile. It is specifically designed to fit into tight spaces where standard, bulkier wrenches might struggle to seat properly on the nipple.

While it does provide a comfortable, non-slip grip, the vinyl coating is also practical for maintaining control during delicate tensioning adjustments, ensuring you don't accidentally slip and round off the nipple flats.

Yes. The SW-9 is constructed from forged and machined steel that has been heat-treated and plated, making it durable enough for professional-grade, long-term maintenance.

It is compatible with standard spoke nipples that match the 0.127-inch and 0.136-inch sizes. However, it is not designed for proprietary spoke systems or aero-bladed spokes, which often require specific, non-standard tools.
