For the bike tech guys and gals,
I did a pretty serious hill ride today - good 9% grade over multiple miles which made me stand out of the saddle a lot more than I am used to. When I got out of the saddle and over my bars, I noticed a creaking sound on every mash of the crank. It sounded like it was coming from the front derailleur area, but I really could not tell. It was one of those things I could not duplicate because when I sat down it went away. At first I thought it was a front wheel bearing because it actually sounded similar to an automobile bearing going, but it was too synchronous with my peddles and after about thirty minutes I felt like I was pretty sure it was in the front part of the drive train. I was in small chain ring and the inside half of the rear cassette so there wasn't any cross over.
Your thoughts? My chain is about ready to be replaced (if not past slightly past due...) I fear that it could be a combination of a wearing chain, and wearing chain ring. I am pretty handy when it comes to fixing, but am still too new to the sport for proper diagnostics.
Here's something else - mechanics are out of control expensive here in Adelaide, Australia (10x PLUS, after exchange rate, to what I paid in Boston for comparable service), so I will do what I can to avoid that... If that means posting a macro shot my chain ring for inspection, just say the word
