Hi

Like the title says, I have this noise that's mostly there only when I'm pedaling hard or riding uphill, otherwise, it won't be heard. I can actually hear it even when I'm stopped -while sitting on the saddle- and push hard on the pedal. It seems pushing hard on either pedal will cause this noise. I'm almost positive it's not the pedals themselves because I already tried lubricating the threads several times. So, what can be causing this noise ? The bike is about 5 years old but it's only used a few months out of the year. And other than the noise everything works perfectly.

Thanks.

BTW, how come when I use the search function the results aren't what I'm looking for ?
