SUPER CHEAP $80 ALIEXPRESS Wheel Hub Teardown | DT Swiss Ratchet Clone
58,871
Published 2023-04-20
This hub uses a very similar system to the DT swiss style hubs and has two ramp plates that take the place of the conventional ratchet and pawls.
On the whole it's not bad and for the price you would be very hard pushed to notice vs an expensive DT hub. The DT hub will be reviewed next week.

I really appreciate this type of content - demonstrating that cheap doesn't mean bad. However, I would point out that for the average buyer, Aliexpress is a literal minefield - it is very difficult to distinguish between cheap-bad and cheap-good, and it's not uncommon for lesser-known Chinese brands to counterfeit better-known Chinese brands. Would be great if at some point you could source a few similarly-priced components from there, compare quality, and let us know your thoughts on what to look out for as a potential shopper.

Impressed by a new investigative microscope/camera… provides great details and analysis as always…

The structure of the hub is almost identical to the new DT 350. The only difference is the "nylon washer", which is a spring in DT350. It's worth noting that all bearings in DT 350 are standard sized, while in 240 EXP, they are 15 x 26 mm. The price for DT350 is around 200 EUR per pair, and I think this should be used in the comparison, not 240 EXP. If you remember, DT recently had a recall of the early models of EXP hubs, because the surface treatment of the ratchet was not done correctly. Even DT itself can make such mistakes, I wouldn't voucher for the unheard manufacturer. I'm very looking forward to your video about the DT hubs next week!

Faffing about with my RC stuff and get a Hambini alert! A welcome break😁 *turns volume down, hits play🤪
-
Can you do a hardeness test on the ratchet components and the hub body on this hub and the DT hub when you get it?
-
Just fitted my Hambini BB this week, something so immensely satisfying with that first crankset spin afterwards!
-
80 eurod aint cheap for a hub, thats the normal price a hub should be.
-
I have the Ztto and Goldix hub on two sets of wheels for over a year. The hub itself is great, but the bearings will only last for about a year. If you’re fine in replacing the bearings then these hubs are a very good deal. I also got the Ztto 54 tooth ratchet and it held up so far.

I’m drunk as hell and gotta go to work but at least Hambini uploaded

Sorry to add to your reading, I could not find any comment below on the hub bearings not contributing to carry the weight of the bike. I changed from freewheel to freehub as the axles kept breaking because the freewheel bearing is so far inboard. Axle failure would be an issue with this design of hub, however the axle is compressing the hub and therefore the inboard wheel bearing is likely to transfer considerable load to the adjacent hub bearing, the axle is compressing the whole unit therefore transferring load to the hub bearing next to the dropouts. (I have a shimano tiagra 4600 rear hub, which as you said have an internal hollow bolt to fix the freehub to the wheel, so it does not have the separate inboard bearings, but the principle is the same to transfer the load to the bearing next to the dropout and avoid fatigue fracture of the axle)

Great to see! I've got a set of ryet rim brake wheels, they are really good for the money. Terrible braking in the wet apparently but I'm a sunshine only rider! The free hub on mine is traditional pawls
-
Small correction: "No need for DT tools" The drive side hub bearing is located behind a part that requires a dt type tool to take off (similar to a cassette lockring tool). It can be a huge hassle to get off because it tightens over time.
-
To be fair - for the price those runout numbers are f@&$ing amazing. I somehow doubt DT would be much better - but it will be interesting to see a similar inspection of the 240 hubs. Nice work
-
Been really looking forward to this one
-
For most of the people Chinese hubs are absolutely fine. It is the middle ground between garbage you get with factory stock builds and competition level DT 240/350. Got one of those. I'll do a review after 2-3K because there's not much you can say about when it's brand new.
-
Great kid friendly video to watch with the grandkids.
-
Good review. FWIW, the RYET cassetes 12sp are really good as well. Much cheaper dan Dura Ace or even Ultegra, and they are even a few grams lighter. Besides the sprockets are attached to each other so the cassette will not damage the free hub. Recommended!
-
Can't wait to see the run out comparison between these hubs and the DT hubs
-
These go together very much like a set of DT hugi hubs I have from around 1993, standard bearings and no special tools! Exactly the same ratchet mechanism.
