The Park Tool SW-7.2 Triple Spoke Wrench: A Versatile Tool for Home Mechanics

For the home mechanic, the Park Tool SW-7.2 Triple Spoke Wrench is the perfect tool to true the vast majority of bicycle wheels. This wrench combines precision-fit wrenches for the three most popular spoke nipple sizes into a single, ergonomically-shaped tool that fits comfortably in the hand. Manufactured in the USA and nickel-plated for years of reliable service, the SW-7.2 fits the following spoke nipple sizes:

• 3.23mm (0.127") - equivalent to the Park Tool SW-0 (black)
• 3.30mm (0.130") - equivalent to the Park Tool SW-1 (green)
• 3.45mm (0.136") - equivalent to the Park Tool SW-2 (red)

Spoke nipples come in a variety of sizes and shapes, and having the correct wrench is crucial. Fortunately, Park Tool offers a comprehensive range of spoke wrenches to fit virtually every size found on bicycles.

To determine the right wrench for your bike, the best method is to use a caliper and measure the nipple across the wrench flats. Keep in mind that most square nipple sizes are within 1mm of each other, so a wrench that is slightly too large may still seem to fit. However, using the wrong size can easily damage the relatively soft brass or aluminum nipples.

The two most common square nipple sizes are 3.2mm (Park Tool SW-0) and 3.5mm (SW-2). Always use the smallest wrench that fits the nipple snugly to avoid causing any damage.

In addition to the versatile SW-7.2, Park Tool offers a variety of other spoke wrenches to meet the needs of different bicycle types and applications:

• SW-0 Spoke Wrench (3.23mm/0.127")
• SW-1 Spoke Wrench (3.30mm/0.130")
