6. How to Replace Your Pedals

Applies to both 1/2″ and 9/16″ thread sizes. The left pedal has a reverse thread.

IMPORTANT: Nuts and bolts on your bike should always be tightened to the manufacturer's specifications.

Replacing a set of pedals on your bike may seem simple enough, but here’s a few tips that will help you prevent damage and make sure they stay on tight for those long rides. I recommend using a proper 15mm pedal wrench for this job, as they have a long handle and are designed to fit properly in the small axle slots.

When removing your pedals, the first step is to make sure you have both wheels firmly on the ground. This will give you better support for the leverage that is required to loosen your very tight pedal threads.

Right Pedal Removal

Loosen the right side pedal by turning counter-clockwise just like any traditional threaded nut. Notice how I have positioned the crank arm and pedal tool so that I can push down with more force.

Left Pedal Removal

It is very important to remember that the left pedal has a reverse thread, which keeps the pedal from unscrewing while you ride. To loosen the left side you will have to turn the wrench clockwise.

Pedal Installation

Before installing the new pedals, apply a thin coat of waterproof grease to the threads. This helps tighten your pedals and keep the treads from seizing, so that they can be removed in the future.

Tighten the right pedal by turning the wrench clockwise, and tighten the left pedal by turning counter-clockwise.

01/23 Will this crankset work with this freewheel?

Hello everyone. I'm new to here so what I'm going to ask might be stupid. I'm trying to fix a bike I inherited but I'll need to change wheels and probably crankset as well. If somebody could have a look and let me know if be really grateful. Also the front wheel's hub is 100mm but my fork's 90mm. I read on other forum it should be ok to stretch the fork to fit the hub in. Is that true? Thanks a lot and have a nice day!

12/03 Gt pedal size issue. Need help

Get guys, forum and bike repair noob here. I picked up a 1994 gt performer (always wanted one when I was a kid). The pedals are in bad shape and need to be replaced. I've done some research and 1/2 and 9/16 are the common size of pedals based on 1 or 3 piece cranks. I've measured the diamater of the threaded end and it's neither size. Anyone know off the bat whit size runs on my gt? It's bone stock btw.... Read more >>

12/03 Im new. Need help.

I have an entry level MB Diamondback Sorrento from 2011 and I need a new crank set and FD. Currently, my bike has a MTB 24/32/42t and my BB width is not specified. I'm looking for a replacement crank set without breaking the bank. If I have to get a new chain or BB then so be it. But I'm trying to avoid a front end rebuild.

For reference, my back cassette is a 7-speed 14-28.

Can I change chainring sizes without getting a new BB? And how do I know it will be compatible with my frame and rear cassette? Insight would be much appreciated.... Read more >>

11/16 Gitane Mixte Crank bearing repair

Starting in on Wife's 1970-ish bike...
Removed cotter-ed crank after oiling pins for a few days.
Brief look at insides.. RUST! 7 Bearing 'assembly' coated with rust... closed that area for now.

At present, soaking crank and gear parts in solvent to remove light rust from chrome... Will examine bottom end cups and cones later today...

This bike will remain steel BB.

Saving grace for both bikes is they were in a garage for entire life....... Read more >>

11/15 Sram Red Non-Drive Bolt Problem

So I attempted to remove this crankset, but the bolt that attaches the non-drive crank arm to the spindle did not budge. Instead, two other bolts that seem to work in conjunction with the one I wanted to loosen have come out.

Anybody have a suggestion on my next course of action?

10/21 Replacement Crankset

Hello all!

So like many others I have had the unfortunate experience of the thread on my right crank arm stripped after only a month of usage (gutting I know!). However, I am not silly enough to try and take the easy and definitely unsafe option of using a helicoil kit (as surely that would just make the hole larger than it already is and therefore the pedal even more so unstable?).

Therefore I am in the market for a new replacement crankset that I can take to my LBS to get replaced.

I currently have the Felt F95 bike, size = 58cm.

10/21 Cranks for Haro Backtrail X2

hi everyone...i'm giving a 2004 haro backtrail x2 nyquist to an 8-yr old kid as his first real bmx bike. He's tall enough to ride with the seat almost all the way down, but the stock one-piece cranks on the bike are way to long to ride in that seat configuration. How do I determine the proper aftermarket crank type and size for the backtrail X2 so I can order a new set? Do I need a new sprocket too, or is the old one (remember one-piece crank) reusable with new cranks? And if I need a new sprocket, must it have the same number teeth as old sprocket to work with the existing freewheel hub? ... Read more >>

10/03 How do I remove this crank?

[attachment=5378]Hi all I found this place by google, Im going to sound like an idiot but I hope someone can help me. Im not much of a bike person but I bought this trike to ride with my kids for fun, exercise & family outings. Unfortunately not long after buying (secondhand) I was riding and the right hand pedal came out of the crank, the crank thread is striped. Through googling I have become aware the reason is who ever assembled the bike put the right pedal on the left crank and vice versa.

Bike is from trike-bike.com.au .[hr]

09/11 Clank sound after 10 miles

[attachment=5352]I hope someone has run across this before. I have a Giant mountain bike and I have been using it on the paved trail a lot lately. Recently, I began hear a clanking sound after I ride about 10 miles. Sounds like when a pedal hits a kickstand that isn't all the way up. I can't duplicate it on a bike stand. It doesn't start until 10 miles and after 15 miles, I get an added rubber squeaking sound on top of the clank. The noise happens in the same pedal position every time and particularly when I'm pedaling hard and hardly at all if I pedal lightly. I had the derailleurs and s... Read more >>

09/06 Threaded Left Crank Arm (Pedal thread)

I shipped my Dawes Super Galaxy home and have just had an unfortunate experience of not being able to re-attach my left Shimano M324 pedal.

It looks threaded, but I still have hopes as I think it's only the top couple of rings on the inside.


From what I can tell the pedal thread is fine.

I know there are tools out there to fix a thread. I'm hoping that mine is not so bad that I need a new crank set. Can anyone offer any advice?
