I've been posting quite some videos about defects on my bike her recently, so I seem to be a winning streak.
On my last ride, a strange noise started to occur on my bike. Might be that it was announcing itself slightly before (and I thought it is chain rub because the barrel adjuster slipped) but not as present as today. I'm 80 percent sure it comes from around the BB area, for me it sounds more like on the NDS, but I could be wrong. It seems like a clicking noise at a certain position, once per pedal stroke/rotation.

It's a Ridley frame, they are using BB386 Evo bottom brackets. I don't know when it has been replaced last time but I had the bike at service during winter and only rode indoors or in good conditions (except one race in the rain). No jet wash and no excessive dirt that could have pressed into the bearing
The noise seems to go away when it put more power on and on out-of-the-saddle efforts (which probably means the same), you should be even able to see that in the riding video, as soon as I pedal a bit harder, it gets a lot better and that's also consistent when I really dig in versus loosely pedaling when coasting.
Not sure how well this can be diagnose via internet, but do you think it is the bottom bracket respectively a bearing? From the characteristic noise, can you tell what is gone, here?
I've mailed this to my dealer as well and he'll take a look, most likely just a bit of grease. He said, it might just be tension due to high temperatures (it was 30°C for the first time, indeed).
Let's see, to back that theory, it might even be gone after the bike sat in the cold basement over night, but it probably needs a fix, anyway.
It for sure was a BB issue. First, it went away when I had the bike indoors in the cold basement, so perhaps the sit and fit of the BB cups has slightly changed and everything is good for now.
However, the dealer offered to take out the BB and regrease everything. From what I can tell now, it is gone, no noise whatsoever on a 4 hour ride in relatively warm conditions with all kinds of load.
Let's hope it stays like that, I haven't had any BB issues for the first 4 years with this bike, so maybe it was just a phase...
