Last couple of weeks, I've been chasing down noisemakers on my bike.
This morning, I isolated an intermittent squeaking noise to my saddle. Once I noticed it, i realized how bad it was. Hit a rough patch on the road while seated, and it squeaks two or three times as I bounce up and down on it. Bounce up and down on it intentionally, and it really complains.
Now that I'm at work, I just isolated it further. It's coming from the leather rubbing on the front corners of the rear frame - just forward of the side-rear rivets.
Time to finally tighten the bolt? Or should I add proofhide between the moving parts to quieten them?
