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.

I hope I'm posting in the right place.

So as I was riding this morning, I noticed my pedals starting to loosen.

Upon closer inspection, looks like the entire crank is loose, but I have no idea how to retighten it.

04/07 Dawes 1500 loose crank/repair price

I have a Dawes 1500, under a year old and started hearing ¨popping¨coming from the crank área. I´ve ridden the bike pretty much every day for the past 3 months since I moved to mexico. I now have some minimal lateral movement in the crank área and was wondering on lets say ¨average¨cost for a repair like this, if there is such a thing. I don´t want to get railroaded when I take it to the bike shop here. Also, in the future could using clip on pedals be better instead of my current straps. I am riding alot of hills and standing for a good part of the ride. Thanks for help and for... Read more >>

03/01 Carrera Subway 2 Left Crank Replacement- Help Needed

Hi all,
my first post on here Smile
Was just given a carrera subway 2, which needs crank replacing. The thread on the crank that holds the pedal is worn and can keep the pedal on. So, I need to replace it. When I looked at it, I notice that the bolt that holds the crank to the bottom bracket is actually not a normal bold, but an Allen Wrench Hex key one. So, my question is if the procedure for removing and replacing the crank wil be same as with other ... Read more >>

02/28 Cross Threaded Crack Arm

Hey Guys,

This is my first post. I did read a lot of the forums when deciding on which bike to buy. I decided on the Vitus Vee 1. Now it has just arrived and I already need some advice from the experts as I have very little knowledge.

I am having problems with the right hand pedal. It screws in a little then stops. When I looked more closely it seems there is a problem with both the pedal and the crack arm threads.

The pedals threads are painted black but there is a part that is silver, showing the metal. So I would expect this means that it is damaged. I... Read more >>

02/25 One piece crank repair

Good evening all.
I have a few sets of one piece cranks, all the same brand, that the sprocket tab (?) has broken off of. I do not have the tabs as they both are from 1985. Does anyone make replacement tabs that can be welded to the cranks so they can be used again? Other than the tabs missing they are in terrific shape and are the stock cranks for my bike.
Any help or info is appreciated.
Thanks...

02/08 Crank Bolt Torque?

I just need a little clarification on the torque specs in the Parks repair manual. In the torque specifications for Shimano crank bolts they give a broad range of torque values(305 inch pds - 390 inch pds).
-How do you know what to tighten the bolt to??
-Should you go to the lowest, middle or the highest torque value??
-If the cranks don't get tight enough, you can end up with a wallered out crank that will never stay tight, right??
-If you go too tight you might split the crank, right??

Sorry for all the ??'s...

01/04 How do i choose the right size bottom bracket for my new crank?


My 1-speed crank need replacing and currently I have a 122mm bottom bracket with it. Ive seen a cheapie 1-speed crank on Ebay for around £15. Would the same 122mm bottom bracket definitely fit this new crank? Or is it the case that all cranks are made differently and might need a shorter or longer bottom bracket?

Thank you...

12/23 Need help with crank replacement

I have a Fuji 1.7c roadbike with the threads stripped out of the right crank arm. Cranks are Fuji branded square taper 172.5mm length and 50/34t chainrings. I found on Ebay FSA VERO ROAD CRANKS CRANKSET 172.5MM 50-34 COMPACT crank arms for around $60.

All of the numbers I can see match up.. Is it safe to say they will bolt up to my bb and line up with my derailleur or is there anything else I need to consider?

I've also found a Nashbar isis CR2 compact crank set for $50 and a isis bb by Nashbar for $20. Would that be a better option for around the sa... Read more >>

11/22 Newbie - problem with pedals

Hello all,

First of all, sorry if I need a bit of explaining - first bike I've owned since I was a kid and I've never done repairs. The other day I was biking to work when I took a stroke forward on the right and the pedal just slipped down. The pedals are now at similar levels (instead of opposite as they should be), making my bike unbikeable, sadly.

I have no idea what the problem is, but there were a few symptoms (I think) before this happened. There's been a clicking noise for a while whenever I take a stroke forward, and the other day I had a bit of a wipe out. ... Read more >>

11/10 Replacing Rings on a Riveted Crankset?

My MTB has a riveted triple ring chainset/crankset and I need to replace it. It is a Suntour SR 180 XR with 24/34/42 teeth. My bike is 21 speed.

Two questions:

1 : Is it in any way feasible to drill out the rivets on the chain rings and replace with discrete chain rings?

2: I have looked online to see what is available in cranksets. The specs of some products indicate that they are suitable for 9 speed. So does the crankset have to match the rear sprockets? Does this have something to do with chain ring spacing?... Read more >>
