DT Swiss Onyx Disc Hub

The Onyx 6-bolt disc 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 disc hub is maintenance friendly and easily serviceable through the DT Swiss worldwide dealer network, and is 100% produced and hand built in Switzerland.

Strength:

~ Better quality than comparable-vintage OEM Formula or Shimano hubs
~ Reasonably light weight
~ Needle bearings

Weakness:

~ 18 points of engagement
~ Weak dust sealing

These came OEM on my 2002 Cannondale F3000SL. Laced to Mavic TXC 3.01 UST rims and DT Swiss Super Competition 2.0/1.8 spokes, the complete wheelset still came in at a reasonably light 1648g.

The Onyx hub is just above the DT Swiss Cerit, which has the same exact internals....but with a heavier hub body. The Onyx rests below the 350 and Hugi, on the DT Swiss hub hierarchy. With only 30 rides on these wheels - I am retiring them as new old stock(NOS) for future vintage collectible. In those 30 rides, they performed flawlessly as expected.

noames   Cross Country Rider [Oct 30, 2011]
Strength:

Almost trouble free.
Easy to maintain (needs only a plastic hammer, hair dryer and, a socket of the right size).

Weakness:

Bearings are on the small size, especially the one on the rear drive side, which is tiny and wear rather quickly!
Advise - replace the bearings once you start hearing noise from the hubs.

Spins very quite, easy maintainance but bearing needs replacement more often than Shimano hubs.

Cliff   Cross Country Rider [Dec 04, 2010]
Strength:

Review is for front hub only. Smooth, fairly light, spins up easily and rolls forever. Six bolt 32 hole. Low maintenance. Durable for a 180 pound xc rider who does not avoid the rock gardens and does 2 foot drops into flat sand dry washes. I paid about $75 a couple of years ago and now it's available in silver for about $60. $40 for non-disc.

Weakness:

Maybe a little heavy for a weight weenie but at the hub you don't notice it so much and for the price you'll be looking a long time to find anything better. I just checked DT's online site and the Onyx is gone and may be discontinued.

Thanks to the riders posting here on MTBR, I went with this front setup and it's been great!!! No problems; took the wheel down to the local shop a couple of weeks ago for a checkup and the mech (top mech overall and an expert wheel builder) said the hub was good to go. For the value, low/no maintenance and overall rideability, it's a winner. Five flamers across the board.

n/a   Racer [Dec 21, 2009]
Strength:

smooth rolling, simple to pull apart for cleaning and overhaul.

Weakness:

I'm a little worried about the seal on the flange side of the free-hub body.

there is a little wobble to the free hub as well but in this price range its expected
(this has not caused any shifting issues and there is less wobble than on the wheel that came on with the bike)

I like the hub a lot, I'm giving it a 4 because of the dirt sneaking in to the free-hub body... but this did not happen under normal conditions, it was at a cross race on an insanely muddy day. It was just soupy shi*... so if your riding in lakes of mud just pull it apart and repack the free hub at the end of the day. I would recommend these.

The rec assumes you work on your own bike.

byknuts   Weekend Warrior [Aug 09, 2008]
Strength:

seems to be good quality, used to have no prob with dt/hugi products, light

Weakness:

freehub wobble, shot pawls?

I figured an light off-road worthy hub would've been strong enough for road and hauling and general riding for someone of my size. Not this one.

Pawls are shot, freehub body is wobbling bad enough to ghost shift my damn bike under pressure.
I can limp it around by soft pedalling but otherwise I'm screwed.
I'd say you could use it on a lighter guy's bike but ultimately, if it goes south under load on what's basically a ROAD bike, well... I figure offroad it's going to get killed.

Built this wheel to haul my kids in a trailer, but no way I would consider this a dependable hub so it's gotta go.

You know I've chopped and generally messed with an original hugi compact hub for years, it's still running fine.
Why's this onyx suck, though dt swiss had improved the hub designs?

Going to end up either swapping over to the woodman or the profile I guess.

Tom   Cross Country Rider [Mar 29, 2006]
Strength:

Awesome bearings, stiff, strong, high endurance

Weakness:

After 2 years of excessive XC use, I did not find any weaknesses (front hub)

This review considers the FRONT hub only. After a lot of problems with the rear hubs (see my review posted in category "DT swiss onyx hub") I disassambled the front hub to look after its condition. I was amazed - the bearings were completely clean, which must go back to a high-quality sealing; they run very smooth and fine. The front hub is highly recommendably for weekend warriors and racers as well.

Jason   Weekend Warrior [Oct 17, 2003]
Strength:

I'm really suprised about the negative reviews on these hubs. After exploding my third shimano silentclutch riding trials I threw on a spare rear wheel I was not using. It was a onyx hub laced up to an azonic butcher. I've been riding all season on this hub and the freehub has been performing as it should be. Countless pedal kicks without flaw.

Weakness:

Not the ideal hub for trials because of the poor engagment mechanism. It will be replaced with a king.

Don't expect anything spectacular- just an affordable entry level hub.

Robert   Cross Country Rider [Nov 29, 2006]
Strength:

The front hub rolls smooth and has replaceable bearings. Available in silver or black; these are fine for the price.
The rear hub has cylindrical bearings (don't loose them during diassembly) and the ONYX website has overhaul instructions and diassembly pictures. They are user serviceable.

Weakness:

When overhauling the rear hub, you'll find it useful to select a grease that suits your maintenance habits. I use a HEFTY amount of synthetic grease to hold up in dusty heat conditions. The pawls engage very smoothly when everything is clean, greased and adjusted.

These are perfectly good hubs, but not the best, but a superb value. Overhaul time is about 25 minutes. Fronts rarely will need service.

Similar Products Used: Chris King - still the best but $$$. Shimano LX and XT
