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.

I was hesitant to mess with my spokes so I approached the task very gingerly. I watched a YouTube video. The takeaways were 1) It's NOT righty-tighty, it's lefty-tighty, and 2) Loosen first (the ones that need loosening), then tighten (likewise), and 3) go easy, like 30 degree increments. The tool itself had a slight burr running along the outside edge of the slots, so I sanded them smooth. But it's a great tool. My bike with steel wheels didn't need much adjusting, but my 2 bikes with aluminum wheels benefited a lot.

OK back up tool.Actually way too heavy 62g awkward to true rims. Also too bulky especially 48 spoke rims.The walls are extremely thick, NO need to worry about spreading/ stretching the channel.VS the Park #2 standard 16g***** drilled out the center 1/2" dropped weight too 56g. This successfully balanced the weight ratio.Also provides a stable finger guide.

The spokes on my bike were very loose and the wheel was way out of alignment.I have never re-aligned a bicycle wheel before. But the bike repair shop near me didn't even bother answering their phone, so I was frustrated and ordered this spoke wrench so I could do the job myself.I read some internet articles and watched some videos on how to do spoke alignment. The first time I spent about 1/2 hour and got the wheel reasonably straight. It didn't wobble from side to side. I tried out the bike and it was fine for about 2 days. Then the wheel started wobbling once again because some spokes had come loose.So I did it again and the same thing happened after a couple of days.Then I found out what I was doing wrong -- I was not getting the spokes tight enough! Not even close. So finally I got them all really tight. Months later the wheel is still fine.My advice if you have never done this wheel alignment before is to check a known good wheel and get a feel for how tight the spokes need to be. Otherwise they could come loose just by riding your bike.

Excelente herramienta, de muy buena calidad, agarra muy bien el rayo (no como una patito que compré antes que se barría y me fregó dos rayos) y es cómoda de usar. Súper recomendable aunque sea para uso ocasional, como en mi caso. Las baratas ni para uso ocasional sirven (ni siquiera una vez me dio buen resultado la patito).

Bought this to replace my favourite spoke key which had died. Works well and is sturdy enough to deal with the dreadful (old, knackered and well on the way to being rusted up - oil every nipple) wheels that I am asked to true. It's worth paying the extra money for such a sturdy tool
