DT350 freehub and ratchet rings are fully compatible with this Goldix GDR-310.

About Yuanan, I am not sure if it is the real factory. For one Goldix MTB MH14, could be for this road hub I couldnĀ“t find in their website.

Bearings:

Front hub: 2x6902
Rear hub: 2x6902 (hub body) + 2x6802 (freehub)

In comparison with a DT 350 hub, the freehub also have 6902 bearings. In a sense, more reliable.

Some weight comparison of freehub and ratchet rings:

Goldix freehub - 44 grams


DT freehub - 62 grams


Goldix ratchet rings- 14 grams


DT ratchet rings - 23 grams

So except the bearing size which is different, the Goldix GDR-310 is a perfect copy of the DT350?

In terms of geometry are similar but not the same.

Also DT350 weights around 360
DT240 EXP weights around 310
And this hubset weights around 320, so in terms of weight they are more similar to DT 240 (internals are quite equal in 240 and 350).

About bearings, freehub are different, compatible but Goldix freehub uses 6802 bearings and DT 6902 bearings (in old ratchet). Comparing with DT 240 EXP, this are a bit better, it uses 1526 (15 x 26 x 7 mm) bearings, so bigger ball race than 6802, so we assume that they have longer life.

In terms of bearings lasting 6902 > 1526 (15 x 26 x 7 mm) > 6802... theoretically.

Just a note: Goldix front hub uses 6902 and I think that it could be enough to use 6802 in this case and this will save some grams.

DT240 EXP front hub 24 holes center lock -> 104 grams
Goldix GDR310 front hub 24 holes center lock -> 113 grams

DT240 EXP rear hub 24 holes center lock -> between 204-210
Goldix GDR310 rear hub 24 holes centerl lock -> 206 grams

I ordered a pair of these Goldix GDX-240EXP:
https://www.aliexpress.com/item/1005003014289678.html

A very close clone of the DT's, except for the spoke offset values. I received them pretty fast and still need to mount them. They look pretty well made, anyway.

OK, I've tested them now on a few rides with long ascents (600+ m) with steep technical portions (the kind of terrain I thought could break the ratchet teeth). Everything good so far, and confidence inspiring.

They make a helluva noise. But that is known. At least the hikers are warned of my arrival. Don't need a bell, just stop pedaling ;-)

i also want to share my experience, bought a pair of Velosa wheels with OEM hubs, DT350 replica it seems, below some pictures.
the ratchet wheel was very bad, i had multiple occurrences of "jumps" over the teeth losing traction on the pedal and it's very dangerous in my opinion especially when climbing.
i replaced the ratchet with original DT swiss 54T and it's like reborn, luckily for me since i wouldn't like to swap the full hub honestly.
on the front wheel, the hub is ok when mounted in the fork, but it has some loose when unmounted.

Well, you seem to have been unlucky. I didn't want to go for the 54T, because I read they were sensitive to dirt and even too much (or too thick) grease, even the original DTs. I went for the 36T, and they are fine so far.

The noise they make is like this (pick your number of teeth):

About noise, I saw in my GDR310 that there is no much grease in the ratchet, so it could be the reason for the loud noise.

The noise is perfectly normal, and the small amount of grease too. Put too much grease in the ratchet, and it will fail, because the teeth on the two rings will not mate properly, the grease getting in the way.

I have the Venfort "Pro4" version of this hub.
Front is perfect, about 500km so far not a single issue.
Rear is about 100km and is also good, except when I stripped it down after 30km or so to make sure everything looked ok. The inner ratchet had jammed into the body. I managed to get it out by tapping the backside with a drift I made using an old screwdriver. I contacted Venfort who told me that the ratchet is inner/outer specific. Although there is no visual indication of this at all. I swapped the ratchet pieces around and have had no further jamming issues though.

As for sound, I ride with a guy that has a DT 360 with 36T ratchet, this hub sounds identical. The hub does have a slight "off centre" sound which makes the volume rise and fall slightly, noticeable when riding but not to a spectator.

The hub came with a spare set of driver bearings also which is nice.

Hi, these hubs looks good for my new custom wheelset, but I have one question: is there the same brake rotor offset as in DT 350? I wonder because I will use two wheel sets from time to time, and adjusting the calliper everytime is quite annoying. I have this kind of "problem" in my road/gravel bike using DT and RYET hubs. Did anyone compared the two (DT, Goldix) ?

I bought a pair of Goldix GDX 370 hubs on AliExpress. The first time I tried to mount a brake rotor on the front hub, the threads stripped out of 2 of the 6 bolt holes! I contacted the vendor, they asked for pictures, I sent them, they told me it was my fault.

Fortunately no such problem with the rear... but I'm not expecting the 36T star ratchet to last very long, after the experience with the stripped rotor holes.

DO NOT BUY FROM GOLDIX.

That's why I use centerlock :) I forgot to mention that my rotor offset differences were on CL hubs.

over 20 carbon wheelsets here - most all all DT350 hubs - all 6 bolt.  Never stripped out one even after repeated rotor swaps.

I am very happy with my Goldix at this moment.
