Park Tool Pedal Tools and Park Tool Grease
Updated · DrPedal is independent and not affiliated with Park Tool
Which to pick
Park Tool pedal tools cover the job most home mechanics need: the PW-5 for occasional pedal swaps, the dual-size PW-3 if you also meet 9/16" wrench flats, and the long PW-4 for shop use or stuck pedals. For Park Tool grease, buy PolyLube 1000 in the 4 oz tube for home use or the 16 oz tub for a busy workshop. Grease the pedal threads every time you fit pedals.

What Park Tool is known for
Park Tool is the St. Paul, Minnesota, maker of the blue-handled tools found in most bike shops. For pedals, that means dedicated pedal wrenches and PolyLube 1000 grease for threads and bearings.
Park Tool pedal tools explained
A pedal wrench is thinner than a standard spanner, so it fits the narrow flats between pedal and crank, and longer, so you get leverage on tight threads.
- PW-5: compact 15 mm wrench for home use.
- PW-3: 15 mm and 9/16” openings for mixed-age pedals.
- PW-4: long professional wrench for seized pedals.
Many modern pedals have no wrench flats, only a 6 mm or 8 mm hex socket in the axle end. For those, use a long hex key from the inside of the crank. Our pedal removal tools guide covers both types.
Park Tool grease explained
PolyLube 1000 is Park’s general-purpose bike grease. Use it on pedal threads, pedal bearings and bottom brackets.
- Clean the crank and pedal threads.
- Apply a thin coat to the pedal threads.
- Start each pedal by hand, then tighten firmly with the wrench.
On carbon or thin alloy cranks, a pedal washer can protect the crank face. For other greases and cleaners, see our grease and lube guide.
Which Park Tool products should you buy?
- Home mechanic with modern pedals: PW-5 and the PolyLube tube.
- Mixed fleet including older bikes: PW-3.
- Shop or seized pedals: PW-4 and the PolyLube tub.
Park Tool vs other brands
Park’s pedal wrenches are built for daily shop use. Generic 15 mm spanners are often too thick or too short for pedals, which is why a dedicated pedal wrench is worth having. For a full list of options, see our tools guide.
Park Tool: FAQ
Which Park Tool pedal wrench do I need?
Check your pedals. If they have 15 mm wrench flats, the PW-5 is enough. If some older pedals use 9/16" flats, get the PW-3. If your pedals only have a hex socket in the axle end, use a 6 mm or 8 mm hex key from behind the crank.
Should I grease pedal threads?
Yes. A thin coat of grease such as PolyLube 1000 stops pedals seizing and creaking. Use anti-seize on titanium axles.
Which way do I turn to remove pedals?
With the wrench pointing up, push its top toward the back of the bike on both sides. The right pedal unscrews counterclockwise and the left clockwise, because it is reverse threaded.
