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 just dismantle, some more pictures:

I will compare with my DT350 hub that I have already... just to see if they are compatible like everybody says.

it could be good, DT replacements are easy to find.

I received the hubs, they look very good! Even one bearing (only one, I don´t know why) is from NTN. The others are from NRW.

My model is GDR310 so, no EXP240 version. The weight was 319, so very good, close to DT 240 in terms of weight.

Do you know any official website for this Goldix brand?
These are some pictures:

The most particular thing, from my point of view, is the red parts. The last one is like a lock ring to keep the spring in the correct position. This is missing in the DT Swiss desing. I think that these red parts are adding a bit of weight, this 10 grams of difference:

I bought a pair of Road Hubs here:

Will see how they are!

I would say that spacers are included for sure, what is not included is the mount. It depends on how the handlebar is, many of them could be installed out of the box without spacers, using normal round spacers (all of them at the end... ) but with a not nice looking.

They updated the site, no 365 grams anymore:

What a deception with Lightcarbon. Its handlebar quality is poor from my point of view and also it weights more than expected. A handlebar with an expected weight of 365+10, weights 440 grams!!! Not a good option.
