ZTTO MTB M1 Boost hubs 28H 54T Ratchet

[tripleDot]

@Aliexpress Test Pilot,
I'll be honest, I had zero interest when you first post about the d.i.y. dyneema spokes. That was until last nite when I saw the review of an Atomic mtb wheel set on YouTube, which was using the Berd's spokes. Actually found Berd's is selling USD8.00 for a single spoke! And I remembered it was discussed here. Very nice topic!

[Aliexpress Test Pilot]

After some Successful single spoke tests I made a complete wheel
I’m still  chasing the weak links I’ve switch to welding the spoke ends as the soldering is too process dependent and caused about 4 spoke ends failures that likely didn’t join well.

Also have some simple to solve issues with spokes pulling out of the hub now that the weak spoke ends are  strong enough.

Still trying to source some small diameter 12 strand dm20 They aren’t really holding tension terrible well but I know there is some slippage in the hub interface

So damn light though lighter than the silvertons or bontrager XXX....bike needs a bigger chainring after throwing some light XC tires on these things.

Has anyone got the correct measurements for spoke calculations?
I can't find the center to flange measurements on the Ali page or on the detailed drawing on the previous page.
Thanks!

BTW they will send with road body and 36t if you ask

I've got about 700 miles on my M1 hubs and they've started skipping pretty bad.  I opened them up and didn't see anything to note on the ratchets.  I may try to clean them up, re-grease, and see if they still skip.  But I'm more than likely going to find a 36T replacement.  Just trying to decide whether to stay off-brand or go with DT branded parts.

Did you all contacted ZTTO?
By their official shop on Ali, is a way.
They seem to care about their customers.

[Aesch]

Yeah I did, they respond quickly and have supplied me with spoke lengths etc. But no reaction on the request for the actual measurements.

Hi folks,

I like buying my wheels from elite on AliExpress because they have great communication and customer service. They offer a ratchet hub that looks similar to the ztto one. I was wondering if anyone here with a better eye and more knowledge on hubs could tell me it these two hubs are the same? I have attached a link to the hub they use:
http://www.yuananbike.com/product/yar-rd14-bike-hub-center-lock-rethcet-system-freebody-36t

Do you think this hub would have the same problems as the ztto? Even with smooth road riding?

Thanks as always!

I did contact them, just need to get around to trying to video the hub skipping to show them proof.  I have had good luck with them for returns and such before.

Yeah, looks like they're ZTTOs OEM.

I've ridden my M2 non-Boost version for around 100kms now, without any issues.
They're giving a 2 year warranty on the ratchet now.

Got the M2 hubs in too! Delivered with road body and 36t ratchet 
Now need to change the front to 12mm. The caps are on really tight, just to be sure: are they pull off type caps too?

Thanks!

Received another M2 hub today, I'll post my measurements later. Asked for 36T/11s which they put, but did not add any grease.
There is a large amount of bearing friction on the cassette hub portion (bearings pressed together too hard?). This is not an issue for normal riding, only freewheeling you'll have extra resistance. On my first hub if you spin the wheel on the stand, the cranks will sometimes spin forward a bit. So I'm thinking this is the cause there.

Yes they are just pull off, held on with oring friction. Mine are not tight at all.
Where did you source the 12mm caps? I was just going to use a cylindrical 15mm adapter like this: https://www.aliexpress.com/item/1005002107520669.html (36g)
This style looks similar: https://www.aliexpress.com/item/32917372157.html

But now that I look at the included 9mm QR caps, could be possible to drill those out for 12mm as well.

edit:
M2 Rear 142mm x 12mm 11s road
- Flange to flange = 53.9mm (LtoC = 36.25, RtoC = 17.65)
- PCD L = 46.5
- PCD R = 53.5
- Spoke offset = 0.8mm

M2 front 100mm x 15mm
- Flange to flange = 58.9mm (LtoC = 23, RtoC = 36)
- PCD L/R = 45.4
- Spoke offset = 0.8mm

The PCD is tough to measure. These numbers are close to the ones I linked a few pages back on ali. Only one that might be far off is spoke offset, need to double check that.

With the hub, this comes with the caps

[cst_jpr]

I tapped the 6902 bearing out on the freehub, it was too far in causing binding. Not ideal for the bearing but oh well.
Reassembling with the thru-axle would press it tighter again, but just on the inner race. My guess is when the press it in they used the outer race with too much force.

Had problems with my 54t skipping. ZTTO asked for video OR picture. in my case pictures of the ratchet was sufficient, "ZTTO Official store" responded within 15 minutes and told me that they would send 36t replacement parts. Replacement parts are still in the mail but I will report back once they are here...
