What type bottom bracket do you have? Is it a sealed square taper?
Can you wiggle the crankarms? Side to side? Independant of each other?
Is the bottom bracket tight enough? Are the crankarms tight? How about the pedals?
Check these and you'll find your problem.
We had a customer with an odd tick. We couldn't find it. New BB, overhauled the cranks, pedals, rear hub all. Finally the boss jumped up and down on the bike and we found a crack in his frame. Thing was, none of us were as tall and big as this guy and we couldn't get his bike to make the same sounds the customer could.
I'm not sure if its sealed or square tapered .... The bike is a 2007 Trek 1500 with an Ultegra bottom bracket ....
There doesn't seem to be any wiggle on either side on the crank arms. They are tight..
I'm not sure how to check if the bottom bracket is tight enough or not..
Doesn't seem to be any wiggle at all on either pedal. Maybe i'll swap pedals for a test ride tomorrow..... just to be sure though.
Don't see any cracks anyplace on the frame...
Hmmm One thing I did forget to check was the chain ring bolts.
Thanks for the input though, much appreciated ...
