Just to add to thread on creaking for archive purposes,
I had a tick or creak during every revolution of crank. But from where was it coming?
I narrowed it down to either left pedal or left shoe/clip.
I rode with my moccasins and it continued so I'd narrowed it to left pedal (It wasn't right side as pedalling with right foot only didn't cause it to tick.
I changed out left pedal for a spare platform pedal and sound stopped! So, I thought it was my Speedplay X/1's maybe a bearing or something. I sent them to the factory, they disassembled them, lubed 'em and sent them back saying all is/was well internally.
I mount them back on crank and .... tick, tick, tick from the left pedal again!
I removed the offending pedal and put a tiny bead of grease on pedal shaft where it contacts outside flat of crank when pedal is threaded tightly in place.
Wah-lah!!!! That was it.
The fix lasts for a few hundred miles, then I have to re-grease it again. No biggie.
I think after having two or different pedals on my crank before buying the Speedplays might have caused that surface to distort ever so slightly which makes for an imperfect fit when using the Speedplays.
