Park SW-1 Spoke Wrench - 3.30 mm
This professional-quality spoke wrench is sized for spoke nipples with 3.30 mm (0.130 in) wrench flats and built for a lifetime of use.
The SW-1 sits in the drawer we open every day. Park Tool design and manufacture it in Minnesota; ProWheelBuilder is an independent wheel builder in Georgia and a Park stockist, not the manufacturer.
What it does
Nipples are soft and the flats are small. A wrench that is a size out will round one on the first hard turn, and then the spoke has to come out.
Which size is this one?
The 3.30mm size. It has to match the part exactly — close enough is what damages the fitting. Measure yours, or send a photo and we will confirm it.
What Park say about it
- Pro quality, vinyl coated, nickel-plated steel construction
- 3-sided nipple interface for secure engagement
- Color-coded for easy sizing reference

About this listing
This is the SW-1 on its own. Tools ship by themselves rather than being built into anything, so it goes out the same day where we can.
How we use it at ProWheelBuilder
We are a wheel shop before we are a tool shop. The Park tools we list are the ones that earn a place on our own bench, not a catalog we resell sight unseen. Tell us what you are working on and we will confirm the SW-1 is the right call before you buy it.
There is a reason the blue handles are everywhere: Park document their repair procedures publicly and build the tools to match, so the instructions stay valid for years.

SW-1 questions
Do you ship tools on their own?
Yes — tools go out separately. Only rims, hubs, spokes and nipples get built into a wheel before shipping.
Is this the right one for my wheels?
Tell us what you are working on and we will tell you straight. A spoke wrench has to fit the part exactly; the wrong size does damage rather than work.
Not sure? Text or leave a voicemail on 470-253-0929 or email info@prowheelbuilder.com — you will be talking to the people who build the wheels.
