6. How to Replace Your Pedals
Applies to both 1/2″ and 9/16″ thread sizes. The left pedal has a reverse thread.
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.
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.
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.
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.
Haven't rode in years, just bought a new MTN Bike and the pedals are a longer distance apart than I was used to.....I want to replace the crank arms w/shorter ones and are the fittings universal? and where can I purchase them?... Read more >>
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 >>
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!

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.... Read more >>
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.... Read more >>
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.

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.
(ignore the cord in the second image, those are my headphones)
In the fourth image, the ball bearings are exposed.

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 >>
my first post on here
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 >>
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 >>
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... Read more >>
