It happens both seated and standing, hands on/off the bars and varies with cadence. Pretty sure it's only under load (pedalling, not just hills), but can't be 110% sure cos the hub is so noisy. Have lubed the dropouts. No new C cages. Cage bolts and pedal spindles are greased. Tried ducky's BB test but no sound. Let a couple of drops of lube drip over the crank/bb join but no improvement. It happens in thongs so it's not cleats. It happens with one leg unclipped (pick a side, any side). Doesn't seem to be any headset movement (if I'm pushing hard enough). Handlebar clamp bolts are secure, chainring bolts are good. Can't seem to get any hub play but not really sure what I should be doing (friend tried that though). Have had a couple of different saddles on it; doesn't seem to matter. Climbing out of the saddle (steep little bit) I can sometimes feel cable twanging under the tape so lubed the cable guides; no change. Figure that, given it varies with cadence, spoke rub and seat post bolt are unlikely.
So, likely BB (which I wouldn't tackle)? Or something I've missed?
Based on your description, I would go with the wheel/frame interface. You've checked the dropouts (which would have been my first guess) but what about the threads of the QRs and all the surfaces where there is contact? What did you use on the dropouts? I'd suggest grease if you used anything else.
OK, thanks. I used a light lube in between the QR flange and the outside dropout surface and onto the dropout contact area. Will grease it, and the threads, and report back. I also tried a different front wheel a while ago, which didn't help.
