That is par for the course for low cost hubs from China. There has been a weird wave of high expectations washing over the community over the last few months..... Having unpacked hundreds of hubs form 9C and Crystalyte let me tell you... you dont even KNOW about quality control. I have unpacked brand new hubs with
* Covers cracked in half
* Spokes stripped and dangling
* rims 1" out of round
* broken wires splayed out
* connectors attached totally backwards and inside out
* ice cold solder joints that dont even conduct
* Holes tapped at every angle you can imagine
* Brakes drilled 1cm off center
* housings rubbing on windings and stator
* total DOA
* wound backwards 6x10 instead of 10x6
* er.. that enough for you?
All of these hubs are dirt cheap. The real variable in this game is how expensive it is for a dealer to get the hubs (shipping on my last order was $2k) and how much they need to mark them up to pay for criminal thieving like the VAT (20% tax) and overhead (employees, storage, inspection, handling, warranty, etc). Oh yea - profit as an afterthought.
Some retailers just sell hubs directly to customers - that is almost criminal.
Whenever I get a load of hubs I take an entire day, a wheel stand, controller/powersupply/throttle, a rag, tools, etc and I open and check out every single hub. This filters out 90% of problems you are likely to find.... but it would not find a problem like we have been seeing with these hubs. Dis-assembly risks way more damage than it is worth - so no retailer would do that under normal circumstances.
Now... I just landed a container full of these and you better believe I am going to spend much more time inspecting these than I normally would given all the troubles. That said - my shipment was post-correction so they should not need any corrective action. On my last shipment (the very first beta shipment to land) one of my customers received a hub that either had or developed a short on the phase wires which resulted in melt-down. It was avoidable (a loud running hub is an indication of a short in the phase wires) but in this case it was not avoided so everybody looses... The customer had all of the inconvenience and I will have to make that right with him.
So.... Before anyone gets too upset about a scuffed wire sleeve, it is good to keep things in perspective. This stuff is DIRT CHEAP from China. Anybody care to make a guess about what it would cost to buy one of these if it were sourced and assembled by one of our fine Union staffed manufacturing facilities???

I just fitted my brand new HT35 which i bought from crystalyte-europe, after reading on the forum about the issue with cable rubbing I thought I'd check out mine before I run the hub. After I removed the plastic cover I found a really deep gash in the cables insulation. I've never run this hub this is how it was supplied to me it cost €220.00 which isn't too bad a price I guess but is still a lot of money and I expected better than this they really need to improve their quality control....

I know that there is a thread on how to prevent rubbing damage but has anyone posted / know how to repair a damaged cable for this type of motor? I've e-mailed crystalyte europe but getting a reply from them is like getting blood out of a stone

so I guess it's up to me with a little help from the mighty sphere.
