15mm bike pedal wrench: the essential tool for easy pedal removal

When it comes time to replace a stuck pedal, install a new crankset, or simply maintain your drivetrain, the bike pedal wrench quickly becomes your best ally. Among the different sizes available, the 15mm pedal wrench is the most common, especially on road bikes, mountain bikes, gravel bikes, or city bikes equipped with standard axle pedals.

What is a 15mm pedal wrench used for ?

The bike pedal wrench is specifically designed to loosen and tighten pedals on the crank arms. Unlike a regular open-ended wrench, it offers a thin, long handle, allowing easy access to the nut located between the pedal and crank.

• Removing worn pedals

• Installing new pedals

• Routine crankset maintenance

• Applying grease to pedal threads

• Quick replacement during drivetrain upgrades

Key features of a good bike pedal wrench

To be effective, a 15mm bike pedal wrench should provide:

Ergonomic handle

A long handle creates enough leverage to loosen tightly fastened or rusted pedals.

Strong, durable steel

The tool must withstand high pressure without bending. Chrome-plated or heat-treated steel models are the most durable.

Thin and precise head

Access to the pedal nut can be tight, especially on narrow crank arms. A perfectly fitted 15mm slot prevents slipping and avoids damaging the crank.

Comfortable working angle

Some wrenches are beveled or slightly angled for better access and smoother motion while tightening or loosening pedals.

Why choose a dedicated pedal wrench instead of a general tool ?

Many cyclists try to use a regular open-ended wrench or pliers. Bad idea! Generic tools lack precision and can round off the nut or scratch the crank. A bike pedal wrench is designed for this specific job: precision, leverage, and secure tightening.

Pro tip: remember the reverse thread

• Right side (drive side): standard clockwise tightening

• Left side: reverse-threaded, tighten counterclockwise

A quality bike pedal wrench sometimes includes a visual marker to remind you of this special threading, avoiding mistakes during removal.

A must-have tool for every bike toolbox

Whether you’re a casual cyclist or a bike mechanic, owning a 15mm pedal wrench in your toolkit is a real advantage. It complements other essentials like Allen keys, tire levers, crank puller, chain tool, cone wrench, screwdrivers, and lithium grease—everything needed for a well-equipped bike workshop.
