Learn about properly removing and replacing your pedals
This task sounds really easy (but isn’t always). Removing or replacing pedals is one of the bike maintenance projects that most will attempt at one time or another. Reasons for removing or replacing pedals include traveling for an event like Rookie Triathlon (in which your pedals need to be removed), buying new clip-in pedals, and just general bike care.
Tools and supplies needed:
Pedal wrench – a normal adjustable wrench will work, but a pedal wrench will help you protect the pedal and provide more leverage for stubborn pedals.
Grease – used to re-grease the pedal threads if dry.
Set of Allen wrenches – some pedals are not compatible with pedal wrenches and require the use of a 5, 6, or 8mm Allen wrench from the inside tip of the spindle.
The first thing to know is that the left pedal is reverse threaded. This means that the right one is “righty tighty” and “lefty loosey.” The left one is the opposite. Viewing from atop the bike, both pedals thread in the direction the bike moves forward. This design is to prevent the pedals from coming off as you pedal forward.
The second thing to know is that pedals are right and left specific. They are usually marked with a small R or L.
Leave the wheels on the bike. This stabilizes the bike for stubborn pedals.
If you ever notice that the threads are dry, add a little grease. Do this once every six months and on every set of new pedals you buy.
The best position for taking pedals off is to stand over the bike with the crank arm that has the pedal you are taking off facing straight forward. Attach the pedal wrench so that it is facing straight back. Hold on to the reverse side crank arm with your free hand and press down on the wrench. This is the easiest way to remove pedals.
When replacing pedals, always use your fingers to start the threading process to prevent stripping the pedal threads. When tightening, make sure that both pedals are snug. They do not need to be so tight that you may have trouble removing.
