Th espindle needs greasing, get a thickish grease take your cranks arms off, and put some rgease on the edge where s[pindle meets bearings, you can just take spindle out too but i find this un necessary, go pedallihng about for around 10 minutes. and it will fix itself.

Nah, it's the cranks. I have hollowbites and I have to grease them every few weeks if I don't want to hear the creaking. It's because the arms are alloy, and the spindle is chromoly or titatnium, depending on which one you have. It's basic metalurgy. Chromoly (or Ti) and alloy don't play nice together. They creak.

You could just pop off the arms and grease the spindle, but since you have the arms off, you may as well take out the spindle and grease where the spindle touches the bearing races. It should take a whole 5 minutes.

Not unless your chain is as dry as the Sahara. There's no such thing as a chain being too tight as far as noise goes. It can be too tight and keep your cranks from spinning freely, like when you do a crank flip, but that's about it. If it's your chain making noise, take it off and soak it in some motor oil overnight (in a can). That'll lube that sucker right up!

Actually it's an aluminum crank arm with steel inserts for the pedal bosses.:wink:

drive sprocket could be crooked or bent/bent teeth,
bottom bracket bearings could be bad,
bottom bracket bearings could need lube,
bottom bracket could be too tight,
chain could be too tight,
peddle bearings could need lube or be bad (not likely)

my bike does that only on the left side. i still have warranty so i called and they are sending me a new bearing. I will tell you if that fixes it when I get it.

If i where you I would:

Take chain off drive sprocket, spin the peddles around and see if the drive sprocket wobbles. (On my old bike there was lock tight on my crank where the drive sprocket bolts on, that made my sprocket sit weird and wobble.)

If it doesn't, lean up against something and peddle with chain still off. If it still makes noise, its probably not chain. Unless it only does it when you peddle hard.

If it isn't the chain, open up bottom bracket assembly.

Look for wear in your bottom bracket stuff like bearings, races (if it has races), ext...

If thats not worn out. Try cleaning and greasing the bottom bracket bearings and races (if it has races). Mainly grease all stuff where metal touches and may rub.

Put the bottom bracket back together. Make sure you don't put to much pressure on the bearings or they could rub/get hot/get ruined.

I hope that helped some.
