Did you ride in the wet recently? Discs are a great source of noise but I've also had my SP dynamo squeal a bit after a very soggy ride. It went away after a couple of rides.

Very soggy commute a couple of weeks ago but I've used it for a 20 mile ride since then with no noise.
Have dropped it into a bike shop to see if they can look at the brake today. They have things like a rotor trueing tool, that I do not, and no doubt more patience and skill too.
If it is the dynamo and it doesn't go away, new hub time?
It is weird in that it is not the usual brake squeal but very much a squeak instead. King of like a bird tweeting

I mean, if the dynamo hub still works, it's just making a noise, I'd keep using it. Might try some spray lube to see if that helps but there's no way I'd build a new wheel just because of some noise.

You don't understand how annoying the noise was! And if it was the hub, surely a sign that it was on its way out.
Bike shop agreed it's the brake rubbing though so should be an easy fix thankfully

I've ridden 800km with an improperly seated tyre. Annoying at slow speed, dangerous at high speed. I'm very well versed in what annoying is. Anyway, as I said of my hub, it was making noise, I kept riding it, it stopped making noise. I'm still using that hub maybe 5 years later.
As for brake noise, well I rode a QR bike across Europe with disc brakes... I've had my fair share of squeaks.You should've been able to diag that by spinning the wheel and either eyeballing the disc in the pads to check for contact or squeezing the pads slightly when the noise happens - it will change the noise, so you know it's the brakes. I'll often pick up grit in the pads and then to get rid, very quickly stab the brakes to dislodge or move it. If it's constant then you can recentre the pads or bend the rotor or to fix it.

Ha, you have a lot more patience than me! Appreciate the tips

I definitely don't. But when you don't have options you have coping mechanisms :)

But it's the BB 80% of the times

Well, I was enjoying an absolutely beautiful ride from Gloucester to Bristol yesterday, squeak free after adjusting the brakes, until the last ten miles when it returned with a vengeance. Quickly becoming not just a squeak but a constant, and very loud, screamingly loud, squeal. After much roadside adjustment and frustration, I took the brake disc off entirely and... It didn't stop screeching.
All suspicion now pointing at the dynamo hub again.

Suspicion confirmed
Extremely rough as well as squeaky.
New hub time since that's cheaper than sending to Taiwan for repair. £54 from Spa cycles, I paid £70, 5 years ago for the original, so that's not too bad.
V annoying that it's not user serviceable but neither is the much more expensive SON

If you're going to replace it anyway, at least try getting some spray grease in there first.
-
• #1389
I will try, as I'd love to get it running acceptably before I can sort the replacement, but there's barely even any gaps where a spray could get in

Any thoughts :
Creak everytime of transfer to right pedal power. I've
- Changed the pedals
- It's not seatpost saddle as still creaks out of saddle
- New BB (cleaned / greased threads)
- Removed chainset, greased etc
- Removed chainring, greased bolts etc
- Can't see a crack anywhere on frame, but it is an AWOL so probably on borrowed time...
- Removed and greased rear mech thread
- Hubs seem fine, no play
- Removed and reinstalled cassette
Running out of things here.... It's not breaks, and consistent on every stroke unless I put no power down at all.
- Changed the pedals

Tighten your quick release / replace for shimano closed cam skewers

Check spokes.

Things that have driven me mad in the past and never sound like it’s the cause.
Cleats
Loose stem bolts
Cracked bars -
• #1394
I once spent ages stripping down everything including the BB and freehub and it ended up being the rack mounts on the seatstays bring slightly loose.
-
• #1395
I’m not telling anyone about the time the click that only happened when seated turned out to be a pair of keys in my wallet.
-
• #1396
Ok, few more things to check there!
-
• #1397
Cleats
classic one. try a different set of shoes or new cleats :-)
-
• #1398
Its flat pedals for me, so no chance of clear clicks.

I was in same hell recently. Spent two days doing all of the above. Turned out it was loose screw holding on the mech hanger. Might be worth a look

That's a good shout. I only have one 5mm screw holding the hanger on, and it was a tiny bit loose.
Been messing about with it now for a while and fairly sure it's the front wheel not rear - it's an SP dynamo with BB7 discs. Think dynamo hubs aren't serviceable? So I'll start with the brake, which might be rubbing just a teeny tiny bit. Being a dynamo, the wheel doesn't spin forever anyway so it's hard to tell if it's just that or if there's a miniscule amount of brake rub.
