Park Tool SW-7.2 Triple Bicycle Spoke Wrench
The Park Tool SW-7.2 Triple Spoke Wrench is the perfect spoke wrench for the home mechanic, empowering you to true the vast majority of bicycle wheels. The SW-7.2 combines precision fit wrenches for the three most popular spoke nipple sizes into one ergonomically-shaped wrench that fits nicely in the hand. Made in the USA and nickel plated for years of service. FIts the following size spoke nipples:
- 3.23mm (0.127") - equivalent to Park Tool SW-0 (black)
- 3.30mm (0.130") - equivalent to Park Tool SW-1 (green)
- 3.45mm (0.136") - equivalent to Park Tool SW-2 (red)
SIZE MATTERS
Most square nipple sizes are within 1mm of each other, so a wrench that is too big may still seem like it fits. However, nipples are typically made of brass or aluminum. Both are a relatively soft material and can be easily damaged by the wrong sized spoke wrench (or poor-fitting off-brand wrenches).
MEASURE TWICE
The best method to determine the correct spoke wrench size is to use a caliper and measure the nipple across the wrench flats. Don't worry about the size of the spokes themselves - spoke gauge is not correlated to nipple size.
TOP TWO
For square nipples, there are several size possibilities, but the two most common are nominally 3.2mm (Park Tool SW-0) and 3.5mm (SW-2) when measured across the flats. Use the smallest wrench that fits on the nipple.
