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.

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?

09/04 Bike makes clicking sound also gear problems

When I cycle my bike makes a clicking sound. Also when I change gear it won't change the first time I have to keep putting it back to the previous one and back to it and eventually it will change. Also when I put it into gear 1 the Chain will come off. This started happening weeks after I brought it I went back to the shop as it has a 12 month warrantee but they said it's not covered under the warrantee as it's wear and tear

does anyone know what the problem is and is it an easy fix or do I have to take to a repair shop?... Read more >>

08/12 Broke a Crank Arm !

The cruisers right pedal felt slightly askew, it was late and only a mile from home. I gave it a cursory inspection, I'd check it at home on the stand.
I gingerly rode on a few revolutions and BAM!

1) Right foot slams to the ground and pushes forward off the toes
2) Gonads pound into the nose of the seat
3) Chest hurtles towards the the bars
4) Body rotates slightly to the right as the right foot is dragging
5) Left foot tries to slide outwards off the studded pedals
6) Every ounce of strength in my being tries to lock my shoulders, pecs and bic... Read more >>

06/29 Older Giant Acapulco Left crank arm falling off

Hello, I just got this bike. I paid 50 bucks which I thought was fair. It is a Giant Acapulco probably from the late 90s/early 2000s. The bike functioned well until today when I felt the pedal wobbling and the pedal fell off. So I was reading a few other forums and they said that the crank arm was most likely the problem. The nut also appears to be stripped. So my question is should I just go to a bike shop and get a new nut or should I just order a crank arm set off of ebay. Also if I order a crank arm off ebay which one should I get. I am looking to spend under 30 bucks for this sinc... Read more >>

06/06 Sram red

Got the Sram red chain rings. Definate difference. The shift is quicker and it does not hesitate at all. Feel much more confident in the bike now. Feels real good. Took it to a park in the area where there are some real twisty trails and quick up and down hills. It requires a good bit of shifting and it really performed well. Super fun ride! Am happy to put this chapter behind me and now just ride!

05/20 Noise coming from crank

Hi there,

There is this random clicking nose that sounds like it's coming from the crank shaft possibly. As I pedal you can hear a clicking noise as if two pieces of metal are tapping each other. It's kinda rusty back there as I had to leave my bike outside during the winter.

What does someone recommend I do?

Thanks....

05/20 Will a 7-speed freewheel work with a single speed chain and crank?

Hello guys

I have a folding bike with 7 speed freewheel in the back. My front crank needs changing. I have seen one but it will only run a single speed 1/8" chain. My question is can I run a single speed crank & chain with a 7-speed freewheel?

Thank you in advance for any help....

05/14 New crank?

Hi all,
As you may remember,I am having a big prob with fd shifting up from little ring to big ring.bike is back in the shop at this time. They are thinking that the trouble is the fsa crank and rings. The rails are notbuilt like the sram and shimano. The cervelo has Rival on it w/fsa crank. we are talking about upgrading at shop cost for materials to shimano crank. I guess my question is do i want to replace the whole crank or just the rings? What would be the advantage to a complete replacement? I was thinking about replacing the rings with red an see what happened.
