Sorry, another "ticking noise" thread!!. Bike has started making a "clicking" noise from the left hand crank or bottom bracket area. Sort of a rythmic.......click,click.......click......click,click..........click......etc, with each revolution of the pedal. However, if I ease of the pedals/power and gently pedal along it vanishes. It's sort of like as soon as I start putting any real power down through the left pedal or putting pressure/weight down through it by increasing effort it starts clicking. Ease off and it goes quiet. Oh - And it only seems to be coming from the left pedal/crank area. Right side doesn't do it. It's a Pinarello FP1 with MOst cranks and Tiagra. Any ideas?.
