I've had this bike for about 2 years now. There is this really annoying clicking sound coming from somewhere in my front derailer. It happens in regular intervals relative to the turns in my pedals. (1 click for every time the pedal goes around) The sound is only there when I put a lot of torque into it when accelerating or climbing a hill. If I am just cruising, there is no clicking. I have a feeling it is coming from inside the axle that the pedals attach to but I can't be sure, that is just where the sound is coming from.
