DT 240EXP hub clones Goldix, Venfort

Or maybe you could try to stretch the spring a little, so it will put more force on the assembly

That also came into my mind. I'm just afraid to bend it too much on one side and make it even worse that way.

Well, they way I see it, you ain't got much to lose...

I depends. If the issue comes from somewhere else, I might have to get a new ratchet unit in order to obtain the spring.

Hi guys,
I have the Goldix EXP 240 MTB hubs (https://www.aliexpress.com/item/1005003014289678.html) for 4 months now. I rode the in the bike park in heavy rain. Even after doing some pressure cleaning - No problems. While maintaining all other parts I also checked the inside of my rear hub. As mentioned all looked pretty decent. The last days I rode my bike again. Uphill, no big deal. But just at the end of the trail the moving ratchet must have gotten stuck somehow. My first pedal stroke at the bottom of the trail went into the void. Also the hub went dead silent when coasting. No engagement at all. Not even slipping/skipping teeth.
The issue seemed to have been fixed easily by removing and reattaching the freehub body. The sound was slightly different though. Back home I took the hub apart, cleaned everything thoroughly  and used only a very thin coating of grease plus a few drops of Fox 20WT Gold. The sound was became super loud but crisp after reassembly.
Today I went for a test spin. Uphill again no problem, even with some hard cranking. Happily I went into some fairly rocky, but fast trail. Again just before the end at full speed my bike suddenly became dead quite. I directly knew that the freehub ratchets got disengaged again. No pedaling possible. Again I just pulled the cassette , including the freehub body off the rear hub and reattached it. The ratchets had contact again.

This is so weird. I think the moving part of the ratchet is being pushed into a jammed position being unable to return. My guess is that either the moving ratchet part is being held back by sticky grease (unlikely) and the spring is too weak to push it loose. Or the "rail teeth" of the moving part get locket up with the rails of the freehub body. Also strange because I cleaned everything and regreased all with 20WT Gold in the first place. And the parts also don't seem to look worn.

Did anyone experience some similar issue or has an idea how to fix that?

Exactly the same problem, or at least exactly the same symptoms. I notices, that outer part of ratchet got stuck in the freehub body, like there is too much play between ratchet and freehub and ratchet to not travel perpendicularly to the freehub body. Any kind of greasing did not helped, new Goldix ratchet in the same freehub did not helped, stronger spring did not helped. Finally I swapped outer part of ratchet with different 36T ratchet, actually from ZTTO and it works flawlessly for more than 1 year.

Wow, that's interesting. I will have a look at ZTTOs ratchet. But for now Goldix is sending me a new ratchet to try.

They also sent me new rather after posting a photos-videos or half ratchet stuck in the freehub body. But new ratchet did not helped, IMHO to problem is that ratchet is too loose in freehub body and there is a space to get jammed there away from the second part of ratchet and therefore dis-engage from each other until you open it, free it and temporarily fixed it.

Please report back if their new ratchets are may be a little big bigger in diameter or may be freehub body more tight.

[maui400]

Ok, that make sense. I will report back if the issue further exists with the new ratchet.

I'm up to about 1200 miles on my Goldix 240EXP hubs and one of the freehub bearings is pretty crunchy. All of the other bearings on both hubs feel smooth, but I will order a replacement set so I can replace them when they fail.


The freehub bearings were pretty easy to remove. How do I get the hub bearings out? The axle is pressed through the bearings and it pretty snug. I gave it a few taps but it didn't budge, and I didn't want to bang on it too hard.


(The freehub uses a pair of 6802 RS bearings. Both the front and rear hubs use 15267 2RS bearings.)

The freehub bearings in my gdx370 got shot after around 80-100km. The ratchet side bearing is very coarse to turn and makes a lot of noise, the outside bearing is tiny bit better. The bearings in the hub is smooth. This gave me a stupid idea of replacing the bearings with NTN ones since i can get them under retail price.
After the bearing change will this cheap hub run better than the og DT one?

As for the sticking ratchets i placed the same white washer as in the shell into freehub body and it works. I tired only using that small red spacer(the one that comes with EXP ratchets) but it was still sticking. With that plastic washer on both sides it works normally.

Really appreciate all the info here. Decided to build a new wheelset and since the goldix 370 have been going quite well for me in all weather commuting, I decided to try another chinese hub. I came across a space grey venfort hub on discount for $65 (!) and matches everything I was looking for (light, older dual 36t ratchet system, road spacing) so I ordered those.

Just got them and they seem quite nice and feels solid. Bearings look good and there is some grease on them too. There are some nicks on the hub bodies and the finish is not that durable. Easy to scratch with some metal calipers. But at $65, I'll give that pass.

One hesitation I had was that there were no drawings/dimension on the hubs to calculate spoke length. I heard other people had success messaging the seller so I did that. It didn't give confidence when they asked for rim depth and not rim ERD. Even providing ERD, they wanted depth. I ended up measuring the hubs myself which was kind of hard as they were straight pull and using the dt swiss spoke calculator. Surprisingly, the spoke lengths were within ~1mm of the length the seller gave so either we are both right or both wrong

Currently waiting on the rims (WG44) and spokes/nipples (pillar 1420, sapim double square) to come in. Will update when I get things built!

I'm looking to buy a set of boost hubs, but now quite uncertain about what to get, having read some of the pro's and cons here and seeing what's available on AX.

so we have Goldix, 370, 350, 240 and 180's.

370's use either a 36t or 60t ratchet made of steel. look like EXP type in some of the drawings but the photo's are old style DT.

350 (https://www.aliexpress.com/item/1005006641370009.html) use a 26T ratchet, but I can't make out quite how that works. looks EXP configuration, but the teeth are angled and looks like there's not a huge amount of contact patch.

240 (https://www.aliexpress.com/item/1005005220417823.html) look more like traditional EXP ratchet, with a 36/60t option (though one poster above said goldix only did them in 60t, which contradicts this) and I see some 54t resale ones. are these compatible with DT ratchets should they need to be replaced?

180's (https://www.aliexpress.com/item/1005004721073940.html) look very similar to the 240's but with the 54t exp style ratchet.

I did see a 72T ratchet setup, I think by goldix too which looked like it'd fail on the first bit of mud. the ratchet teeth angled 30 degrees or so, so likely not cross compatible with anything else. I actually see it posted on p9 of this thread..

Then there's venfort, who have had mixed reviews, but do look like you can swap out the ratchet with genuine DT ones if it goes, though uncertain if that's just an issue with the 60T version, or if the 36T is OK?

The ZTTO M1 hubs folk talk about seem to not be sold on AX anymore?

I'm tempted to go venfort, 36T unless there is a compelling argument against?

Hello,

Could you tell me what model is this hub?




It looks similar to a Goldix and I managed to use the DT350 freehub but... More images, does it ring a bell to you?

[olavrb]

Looks like they might be made by H-Works? https://h-works.cn/collections/hubs

[ultreia]

The thing is h-works HW-261 looks similar to the advert picture but the hub built in the wheelset is another. If you look at the pictures taken directly from the wheel you will see what I mean.

[edfungus]

Finally got my wheel built with the space grey venfort hubs. Very uneventful; so far so good. Built like any hub as well. I honestly thought I would have more thoughts but this is it for now
