Why does my bike make a noise when I pedal hard? When I pedal forcing a little with my right leg, the bike makes a noise that I don't know how to describe. I'll try to do it. It's like:


a short "ting"
a tiny bell
if a small rock hits the down tube


I don't know what is causing this noise, but I think that it could be any of this things:


pedal
crank arm/pedal connection
crankset


I think the material of all these things is alluminium.

I don't feel anything (like a bad shifted chain) when I hear the noise.

It happens when there is movement and when there is NO movement (I use the brake, so the bike doesn'e move, stand using all weight on right pedal, and it makes the noise)

The pedals could be in any position, It is not in a particular position. Just pressing the right pedal.

Has someone else has this "problem"? Any ideas of where this comes from?

Update:
Yesterday I took out the chain and stood on the right pedal, and made the noise. Then is not the chain, nor the transmission system.

I put oil in the pedal axis, but had no luck. Also tried to loose the pedal, but the juncture point is too tight, and I couldn't.

Today I will try to use oil in the bottom bracket.

Update: here is a link to info on the bike http://www.diamondback.com/2012-sorrento maybe it helps to know the model of all the components.
Could be any number of things.  The first thing to check (because ignoring it can rapidly cause expensive damage) is that the crank arms are tight.  Even if they don't seem loose it doesn't hurt to put a wrench on the fixing bolts and torque them a bit.  (If one moves more than a small amount, get a torque wrench and do them up right.)  Likewise with the pedals.

You can also get noise from a cartridge BB if the cups are not totally tight. No big emergency here, but you need to tighten them to see if that's the problem.

Spokes can make a "ting" sound, especially if the wheel is relatively new.  Unless there are loose spokes, though, there's not much you can do about this and it will usually go away on its own after the wheel breaks in.

It's unlikely to be that the BB needs lube, unless it's been sorely neglected for years (or submerged in Sandy's tidal waters).

If the bike is relatively new (a few months old), you should take it back to the shop where you bought it and ask for a "tuneup" where they would tighten the crank arms, adjust the brakes and shifters, and true up the wheels.  On a new bike they should do this for free or for a nominal sum.

If the bike's older a tuneup won't hurt, but expect to pay more.
