My road bike squeaks when I shift to bigger cogs with the rear derailleur. For some weird reason, I don't seem to hear the squeak until the 2-3 mile mark and then it progresses to every downshift eventually. Doesn't seem to matter what ring in front I'm in.
I thought it might be my cleats... I know that doesn't make sense but it sounds just like the squeaking from a Look cleat that needs to be lubed or changed. I made the change and the squeaking hasn't stopped or changed.
The bike is relatively new. Shimano 105 10-speed. About 1200 miles on it. I don't ride this bike in the rain per se, but it's seen a few drizzles and I ride past midnight often when there is lots of fog around here. Is it possible that the squeak is coming from the cables?
Thanks much for any help.
