Hi!
I am having an issue with my Shimano Dura Ace 7900 Crankset.
When I push with the left foot I can hear a loud click. That happens when the left crank arm is almost vertical (7 or 8 o'clock).
I notice that with a clean chain the noise take 5km to reaper. But after that it's continuous.
I lubed/greased everything, checked that noting was on the way of both crank's arms.
Finally I first tried with another crankset (Turativ rouleur) and then the noise disappeared.
I then took the chainrings out of the Shimano crank and replaced them with the Turativ one's (those are "classic" with the bolts made of 2 parts as opposed to the Dura Ace one's that you screw directly into the big ring).
I am wondering what could be going wrong with the chainrings...
Iactually started to get this problem when I installed the crank into my new frame. I had one of the chainring bolt coming loose on the first week and I noticed it only after a few hours riding... It was already noisy anyway.
I am wondering if the issue is the big ring or the bolts...
Thanks for your comments
