Pedal Tools

Swapping pedals or repairing stripped threads is simple with the right gear. Our pedal tools collection offers everything from professional long-handle wrenches for maximum leverage to specialized speed wrenches for quick installs. Whether you need a double-sided wrench for your home garage or a Crowfoot attachment for a torque wrench, these bicycle tools deliver a precise, slip-free fit.

Frequently asked questions

Which pedal wrench do I need for my bike?

It depends on how the pedal grips. Older and many current pedals take a 15 mm wrench on the flats at the crank arm, served by the Pro Pedal Wrench 1613/2BI. Most modern clipless pedals have dropped the flats and use a hex on the inboard end of the spindle instead. Shimano SPD-SL and SPD, standard Look Keo, and Wahoo Speedplay Zero use 8 mm hex; titanium-spindle models like the Look Keo Blade Carbon Ti and Speedplay Nano use 6 mm hex. The 3-in-1 Pedal Wrench 1620/2P-US covers all three in one tool.

Do I use a 15 mm wrench or an 8 mm hex for clipless pedals?

Check the pedal first. If it has wrench flats on the spindle next to the crank arm, use a 15 mm pedal wrench. If the flats are gone and there is a hex socket on the inboard end of the spindle, use a hex key. Shimano SPD-SL and SPD, standard Look Keo, and Wahoo Speedplay Zero use 8 mm hex; the Look Keo Blade Carbon Ti and Speedplay Nano use 6 mm. The Speed Pedal Wrench 8 mm and Speed Pedal Wrench 6 mm cover the hex side.

How tight should bike pedals be?

Pedal axles thread in at a typical 35 to 40 Nm; Shimano publishes 35 Nm, and some makers spec up to 40 Nm. Run them to the upper end of the band, because a pedal that backs out can chew up the crank-arm threads. Grease the threads first, and defer to the pedal maker's published value where one is given. A long-handled Pro Pedal Wrench 1613/2BI gives the leverage to reach that torque cleanly.

Why does the left pedal turn the opposite way to loosen?

The left pedal is left-hand threaded. Both pedals use the same 9/16 inch by 20 TPI thread, but the left side is reversed so that pedaling load tightens it rather than backs it out. The practical takeaway: the left pedal loosens clockwise and the right pedal loosens counter-clockwise. A reliable shortcut our mechanics use is to turn the wrench toward the rear of the bike to loosen on either side. Getting this backwards is the most common way to feel a stuck pedal that is actually just being driven tighter.

Can I fix stripped or cross-threaded pedal threads in a crank arm?

Often, yes, if the damage is in the aluminum crank arm rather than the steel pedal axle. The Crank Saver Kit 1695MB1-US chases and recuts the 9/16 inch by 20 TPI pedal thread to clean up cross-threading or light stripping, and where the thread is too far gone it sets a steel insert. Note this is a thread-repair job, not the same as the Pedal Genie install aid, which spins the cranks during a build and does no cutting. In our experience, catching a cross-thread early, before it is forced under pedaling load, is the difference between a quick chase and a new crank arm.
