    I have no idea what a rod is, but your exclamation mark button appears to be stuck, and you seem to have a bold, large-type problem as well. They may be related.

    I had an issue where if I coasted and then applied a decent amount of power right away I'd get a loud pop that I could feel through the frame and sounded like the crank area. It ended up being the rear hub. It wasn't on a Madone though, it was a Superfly (Trek carbon hardtail 29er with bontrager wheels)

    A number of FH-6600 Ultegra hubs with sticky pawls got out into the market some years ago. The usual symptom was one loud pop when applying power after low-speed freewheeling. Most people ignored the problem because it occurred infrequently and at very low speeds only. From what you're saying or trying to say, it could well be that—especially if you've got the FH-6600. If it is, no big deal. I'd ignore it.

    Try tightening the seat post clamp I had a similar problem when applying down force.
