bloody forurm..
Tried an edit and got signed out....lost it all
Anywho, I wonder what effect there is on noise from an out of balance wheel/tire combo. Pros balance their wheels and some will priortise out of vertically true for weight balanced and pefect rotation, or use weights like car wheels and stick on weights.
With old drying sealant it can have a significant effect on the wheels rotation. As much as making the bike lurch up and down when on roads - extreme example, but could just a valve stem be enough to make the wheel accell/decell during rotation and contribute to this noise imbalance?
Would be more noticeable without a rider sat on it.
If you want a 36T ratchet I'll happily do you a swap, pretty sure I have an almost-new 36T set in my hardtail
I balanced the wheel with blue tack and it made no difference (vibrations went away but not the noise), I have however ordered golf club balancing weights to balance it..
Here's one guy who silenced his DT hub by literally filling it with grease
..what really quiets the hub down is grease one the sides of the ratchets not in between the ratchet surfaces (where it quickly gets rubbed off). The grease on the sides stay put and act as dampers presumably.
So where can I order wave springs??
I purchased a secondhand wheelset for my ss mtb. They are dmr revolvers or something. They are near silent. It’s very enjoyable to coast in silence with only the tyre noise for company.
BTW springs needs to be approx max 25.5 mm OD and minimum 18.2 mm ID, they have 4.15 mm free space to along the axis of the axle (so each springs needs to be more than 2.1 mm tall) and need to exert about 2.6 N of force each on the pawls when locked together. The disc springs I've found are either too short or exert 10 times more force than that - i.e. they're too stiff and tall.
Ordered the DT 370 3 pawl hub as it sounds a lot nicer and more even and spins with less drag from what I've seen - lower engagement not a big deal for road use (24 POE I've read).
I can borrow the tools required, otherwise it's £38 for the freehub £15 for the drive ring and £5 for the spacer you need, not cheap but guess I can sell the old freehub an ratchet.
Problem solved, got the wheel rebuilt with the Newmen Fade hub, shop reused spokes and brass nipples and total cost after selling the old hub was £160.
Might add a bit more grease to it to turn down the volume, but none of the extreme oscillating sound the DT had, lower weight and 33 POE.
think less, ride more
This. Sounds like OCD to me.
Not a criticism. I'm exactly the same with my bike e.g. completely destroyed a perfectly good Giant dropper post after disassembling it to try and fix a slight bit of wobble that really wasn't an issue.

Sounds like presbycusis to me.
Did you see/hear the 54T video? It sounds like the rear wheel would explode into bits with an insanely loud uneven BZZZZ zzzz ZZZ zzzz amplified by the deep carbon rims, the video didn't do justice to how bad it got at high speeds. Once aware of this I wasn't happy with just muting the sound a bit with the 24T ratchet.
Maybe you don't mind bottom bracket creak or random sounds from your bike - YMMV.
It's still oscillating.

Yep. Don't tell him though.
Sounds pretty much the same to me.. Could have saved yourself £140 and just stuffed a £10 note in each ear.!! 😉
