This was driving me crazy all morning: while pedaling, there was an intermittent "tick tick" that sounded like a derailleur cable hitting against the frame. I isolated each cable individually while riding by pinching it with my hand, but the noise persisted. Any ideas what might be causing the noise? It sounded like it was in the BB area, but nothing is loose that I can see.

Pedal Spindles or Bottom Bracket..

You can check the pedals for tightness yourself with the right allen wrench. Bottom bracket is a shop job for most.

There is no universal source of ticking noises. It could be caused by any number of things. Often the noise seems to come from the BB but turns out to be caused by something else entirely.

Here are common methods to narrow the search. Does it make noise while pedaling only? When standing? Depending on the answers, you can eliminate possible causes.

If the noise continues while coasting then it has nothing to do with your drivetrain. Check skewers, spoke elbows, and nipples. If it stops while standing then it has something to do with your saddle. Lube saddle rails at the points where they attach to the underside of the saddle, lube between saddle rail and seat post clamp, and remove seatpost and reinstall with lube (depending on frame and post material).

Any two parts that come in contact with one another can be a source of a creak. They do not need to be moving parts either. The smallest amount of movement or flex can produce some ear-piercing creaks. The following is a short list of items to check when searching for sources of noises:
-BB in frame
-BB spindle/chank arm
-chainring bolts
-pedal threads
-pedal cleats
-stem faceplate bolts
-wheel skewers
-Spoke elbows
-saddle rails
-cable boss/housing ferrules

Good Luck!!! ;)

Does it correspond to cadence? (which would suggest pedals or BB)

or

Does it correspond to speed? (which could be the hub)

Does it correspond to pavement conditions? (which might suggest stem, seatpost, fork)
