Click in my left pedal

New bike, new pedals.

Did about 10 miles on it and noticed a click in my left pedal only when I'm really pushing it. When I'm cruising I can't feel it. I don't feel any play (by hand) spinning the pedals or pushing/pulling on the crank. Any ideas?

What kind of pedals are these? You need to be very specific in order to get proper advice.

Probably the pedals aren't the problem?

Who knows what the problem is? It could be the pedals, it could be the shoes, it could be the crank etc etc. We need specifics about the problem to properly diagnose

Reading your post again I have an idea that it is likely the crank arm. Is it really a click or is it more of a slight jump in the pedal that you feel on the downstroke? Does it feel like the pedal is off axis when you pedal? What kind of bike is it? what kind of BB spindle does it have?

How old are the pedals? Can you feel any play if you grab a pedal and try to move it up & down?
We need more info!

Since this guy has been posting the Fixed Gear forum I am guessing he has a Square taper spindle. Since the complaint is about the left side pedal I am betting that he has a trashed left side crank arm, and it is not his pedal.

Wow, some quick replies!

The bike and the pedals are brand new, only 10 miles total. I feel the click under my foot when I'm pushing down, right when the crank passes 12:00. I thought it was the teeth on the pedal rubbing the tread of my sneaker, but I used my heel to pedal and felt the same thing. The bike is a Gavin Solo, IDK the brand of the cranks but their stock. I went to my bike shop and swapped out the toe clip pedals for some generic jobs.

Edit: Oh, I have the hub on the freewheel side.

Sorry to tell you but I am almost certain you have a trashed left side crank arm. Too bad that looks like an expensive crank.

This happens a lot on fixed gear bikes when the spindle bolt is not properly torqued down prior to riding. You can try torquing it down really hard and hoping it works, but you have about 20% chance that it is not destroyed.

Here is what happens:
when the bolt is not torqued enough the weight of the rider will loosen the bolt a little more. Then when you pedal the hardened steel square spindle rubs on the soft alluminum arm and reshapes the square hole. It doesnt take much before the hole does not securely fit the spindle and the arm is trashed. Usually you feel it in the pedal at 12:00, its because there is now play between the crank arm and the spindle.

Unfortunately the only way to fix it is with a NEW crank arm.

Sorry bro, that SUCKS!!!!!

BTW, try to find out the brand of cranks, those look friggin sick I'd love to get a set if they are any good.

Also if the LBS assembled the bike for you then they are responsible to replace the crank if they did not properly torque it down. If you just bought the bike TAKE IT BACK and DEMAND THEY TAKE CARE OF IT. DO NOT TRY TO FIX IT YOURSELF or they will blame you.

Agree with soop probalby is the crank, take the cranks out, put grase on the axle, put the cranks back and tight them really well.

Sweet. I'll check the crank arm. Naah, I got this bike off the net like 75% assembled. The bike shop was nice enough to install the pedals, check tire pressure, yadda yadda yadda.

You can check to be sure that its the crank arm like this:

Stand on both pedals with the left foot foreward.

take your weight off the pedals and rotate them until the right pedal is forward

now stand on the pedals again- do you feel the pedal "give" a little bit ?

If yes then it is definately the crank arm.

I just had a new set of MKS pedals that clicked until I greased them properly.

I'd call the company you got the bike from and give them hell about it. They should either take the bike back or send a replacement crank to you. whoever assembled the bike is at fault.

I promise these arent the pedals, its the crank. It happens so often that most bikes switched to splined spindles. The only ones that still use square taper are the track bikes that they sell these days, or cheapo wallmart bikes.

If you put 10 miles on the crank while it was like that then it is for sure trashed, no amount of tightening that spindle bolt will solve the problem, not even removing it. lubing it and putting it back on. The shape of the hole has been altered and it will no longer function correctly.

Sorry for all the separate posts, I'm A.D.D.

Put some dirt in the other pedal and in a week both pedals will click!!!

No, the bearings are going out be cause they are cheap or got dirt in them. Take "THE BIKE" to the shop and get the click fixed.

It could be the bottom bracket also that's why I said take the bike.

You arent paying attention to the symptoms- the click happens at 12 oclock in the rotation, if it were dirt in the BB then the click would happen sporadically, and would be more of a grinding than a "click". It's the crank arm.

I repacked the pedal bearings with some Belray waterproof grease. I tried taking the crank arm off to reset it but that biatch wouldn't budge! I even wacked it with a rubber mallet a coupla times, no good. So I just tapped it back toward the BB a few times and tightened the bolt. Took it for a quick spin and it's a little better but I still felt something a coupla times. I wonder if it actually is the tread on my sneakers? Even though I have different ones on today????
