Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

One way to check that - jam little squares of card in the crossings.

Did you try 1-legged cycling?
Does the click occur at the same point in the clock relative to the pedal positions, and if it is, does it change if you change gears ? Or is it completely random when the noise occurs?

To fully eliminate pedal/cleat possibility, you could swap in some platform pedals and see what happens.

Since it happens under heavier loads there’s no way I can do one legged riding.

I can’t imagine it’s the pedals or cleats. I used the same combination for 500 miles before this issue started.

Well, YMMV, but recently I was convinced that I had BB creaking and it turned out to be in the stem. Yeah, under heavy load you may be leaning on the bars more, and the front end becomes suspect.

When I took the bike into the LBS, the mechanic said, "everybody always thinks its the BB, but it could be anywhere."

And that's the point, it can *sound* like it's coming from the cranks or BB, but it could be anywhere.

Unless you are really good, I suggest a trip to the LBS.

I try all sorts of stuff to reproduce the sound off the bike, then you have a chance of narrowing it down.

LOL, had this happen this morning, it was driving me nuts, until I realised that a shoe lace kept hitting the crank.

You sir or madam are in my debt. If you are in SE Michigan I owe you a beer or 2. There are others with the same suggestion if I recall. Thanks to you all.

I feel foolish, dismissing these suggestions, but it finally clicked. Loose skewer, flexy rear triangle, especially under load. Duh! Just came back from a ride and the angels sang once again.

It's not madam and you don't owe me anything. I've been there before. I've even switched out press in BB bearings when all I had to do was tighten that rear skewer. Lot's of force happening around that part of the bike.

Glad I could help, enjoy the quiet.

In the vintage steel frame days you would've torqued the wheel into the chainstay.

I may know that from experience..... Or not..
