The Onyx MTB hub features DT Swiss proven technology, including the DT Swiss quad bearing system, high grade seals, optimized flange geometry and spoke hole chamfering, and utilizes a proprietary 2-pawl system with eighteen points of engagement. DT Swiss Onyx hubs are priced at the lower end of the DT Swiss lineup, yet offer better quality and performance than most OEM Hubs. Onyx hubs offer a great alternative as a hub upgrade.
The Onyx MTB hub is maintenance friendly and easily serviceable through the DT Swiss worldwide dealer network, and is 100% produced and hand built in Switzerland.

Strengths: Relatively light, dependable
Weaknesses: None
Bottom Line:
Got these on a used wheelset and have had no issues after two seasons of pretty tough riding. The freewheel, although not intricately toothed, is smooth and has been very reliable (contrast with the review from Austria). These retail for the same price as XT but in my opinion are superior, especially when it comes to the bearings. I have bad luck with two XT rear hubs getting their bearings smashed while the Onyx still roll like buttah.

Strengths: Good looking, affordable price
Weaknesses: Poor ratchet system, endurance of cardridge bearings
Bottom Line:
This review considers the REAR hub only. After one year of hard XC use, the ratchets broke .. I replaced them for 30 $. Well, one year later, same problem again - and the bearings are also completely worn out. This hub construction, which only consists of 2 small ratchets which have to engage the wheel is simply not sufficient to meet hard XC requirements. However, this product is not that bad, but I don't recommend it for excessive XC use. For the front hub (disc edition) consider my review in "DT swiss onyx disc" category. Greets, Tom
Strengths: They are standard on the Rolf Uracco wheels which are very light, and the hubs are as smooth as butter when working...
Weaknesses: The rear hub that is on my wheelset came with a lot of problems, where as I enjoy giving stuff I buy my own set of problems... see below...
Bottom Line:
I got these hubs on a Klein Attitude Race I recently purchased with the Rolf Uracco wheels. The wheels are very light which is a nice bonus, and the front wheel seems to be holding up very well, but the rear hub has given me nothing but trouble. At 33 miles the bearing retainer cup cracked. Klein was very quick to replace this part, as they should be with a $1700 bike that has been ridden twice. After getting the wheel back it ran real well for another 43 miles. At 76 miles it developed a terrible knock. Back to the shop I go... I was told that a bearing seemed to be bad and it should be fine to ride until a replacement came in. Sounded good to me. The wrong part was sent the day before I have to leave to go on a bike trip to Ohiopyle, PA area. No big deal to me cause the guy said I would be fine riding it. After about 5 miles of riding around on a converted railroad bed (pretty easy stuff) I notice that my hub seems to be pretty quiet while coasting, so I figure I better turn around just so I don't have to walk 5 miles if the hub craps the bed... On the return trip, I make it 2 miles back and my pedals no longer engage. I pedal, and nothing happens. Understandably, I get pretty hot about the deal, but still keep myself under control... until some lady on a powder blue and pink Huffy that hadn't been lubed since it left K-Mart 12 years ago goes blowing by me as I walk back to my car. I kind of snapped and called everyone that I could a number for. So, as of now, I can't give this hubset a good review, but Klein/Trek has agreed to give me a new wheel because of the number of problems I have had in such a short time, so if this new rear wheel works out fine, I will post another review and chalk up my experience as a possible "lemon/dud" that could have slipped through with a few problems. I am really trying to love this wheelset because of the weight, but I am having some problems doing so as of yet.
I would give it 3 stars because of weight and the front hub, but because I got passed by an old lady wearing a nice pair of Wranglers and riding a squeaky huffy while I walked my $1800 ride back to the car, I give this hubset a stinky 2 (it would be a 1, but I think I just snagged a bad luck wheel so I will give them the benefit). Like I said, I will definately repost after trying out the new wheel because I hate it when people don't have much good to say about a product, so keep an eye out for the update.
Similar Products Used: LX, XT, XTR... Can't go wrong with XTR. Sure they are a bit heavy, but every shop that is worth a hoot in the country will have the parts to service Shimano hubs on hand in case of any problems.
Bike Setup: 2001 Klein Attitude Race... all off the shelf components because I haven't have enough time to wear anything out yet.
Strengths: 2-pawls mechanism, high-grade seals, easy disassembly of rotor unit, patented quad-bearing system. serviceability. And ofcourse they look very nice also.
Weaknesses: Non.
Bottom Line:
Very nice hubs which will last for a long long time.

My DT Onyx rear hub bearings have ended their life after only 15000 Km.
Should I need a special tool for the removal of the old bearing pair and the insertion of the new ones?
