My gravel bike is making a clunking sound when I'm pedaling. It's a oneby. I only seem to notice it on the harder (smaller) gears. It's cyclical, but doesn't seem (??) to match with either pedal or wheel revolutions. In this clip we can hear 3 consecutive "clunks" repeating every few seconds, but depending on the gear or the load (I think??) sometimes it will only be 2 clunks. The bike is 1 month old and this started maybe 2 weeks in.
You might need to turn up the volume a bit in order to hear it, but you can't miss it.
