Pothole & Loud Noise
I unexpectedly slammed into a pretty big pothole tonight and my bike made a very lound ::CLANK:: sort of noise...
I am used to hearing the noise of the brake/shifter cables smacking against the frame, but this was a much more solid sound that I can only compare to the sound that my skis make if I smack them together while skiing...
This felt like it came from the fork area, but I couldn't be sure at the time. Any ideas? This is what the front wheel area of my bike looks like:
The clearance is low, is it possible something made contact? The other thing I was thinking is maybe the spacers on my steerer are not quite snug, and it smacked into the frame?
The loud crack noise is common with modern bikes although I'm not sure what the cause is It sure sounds bad but I don't think there is anything to worry about.
I've experienced the noise with both of my bikes and have never been able to determine what the cause is. I think it comes from the threadless fork/headset interface but it may be comming from the handlebars slipping in the stem - not sure, obviously.
Sorry I can't answer the question but thought I'd share.
My bike's better than me!
Is it possible that the tools in your seat wedge bag smacked into your seatpost when the bike took the jolt??
Sound travels through bikes. What you hear in one place may have actually occurred in another....

Most likely the chain slapping either the chainstay (which is why they have chainstay protectors) or something in your bag.
no bag on the bike, so that's not it.
all of the above seem plausible, buti can't find any real damage, so i'm just going to pretend it never happened.
I have occasionally been in a group on a rough fast downhill and the racket coming off some bikes was pretty scary...nothing apparently was amiss. I don't know if it a tubing resonance or what. Some Carbon fiber forks sound like a sword fight with PVC pipe on rough roads (my reynolds and lightspeed are quiet, however). I believe that if you had done damage, you would feel funky handling. hope so anyway!
I agree with the poster above..

Chain slapping against chain stay. If you were on a small cag at the back, this is very likely to happen all the time when going over bigger bumps. That's why you have chain stay protectors.
