I have had an irregular ticking sound coming from the pedal – bottom bracket area since this summer. The ticking doesn’t follow any particular pattern. It can start right away or sometimes it takes a mile or two to get going. It only makes the sound when I pedal and going faster or slower doesn’t make a difference. I can’t duplicate the sound just by turning the crank on a workstand I have to be riding it. I believe I’ve checked all the silly stuff like loose spokes, cables etc.
It started when I transported my bike upside down for a vacation. I also put on a new pair of cage pedals at the same time. At first I thought it was the pedals, so I inspected them and made sure that everything was tight. However, the sound remained. I took it to the LBS and had them replace all the old cabling and lube everything, which needed to be done regardless. Still the sound remains. Finally, they replaced the bottom bracket (I’ve had a similar sound on some other bikes and replacing or lubing the bottom bracket has always fixed it). Yet the sound remains. I suppose I could replace the pedals just to make sure. Is it possible the LBS didn’t install the bottom bracket correctly? Or is there something else I should consider? FYI…my bike is a ’03 Trek 7500.
Somebody last month posted a similar problem, but I can’t find his post. I would like to know how his turned out.
