Shimano Dura Ace 9000 Hubs - how good are they?

Postby Stevo C » Wed Nov 27, 2013 14:37 pm

I'll come clean from the off - I've actually ordered these in a moment of weakness. I didn't even know I needed any hubs. They were £235 at Evans (when the £5 voucher is included), which seemed just too good to pass up. I ordered them in 24H/28H and will almost certainly be pairing them with the obligatory archetypes.

I was just looking for reviews and am struggling to find anything . There's plenty of reviews of the rest of the groupset, but nothing hub specific.

For £235 they are excellent. They are possibly the perfect hub good blance of everything.

They're top notch... probably the best out there

Top work chaps - exactly what I needed to hear. Reckon I might try the reverse psychology approach this time:

Me: " look at these, aren't they wonderful etc"
Her: " very nice darling, how much were these then?"
Me: "£235 - and that was cheap"
her: " Very funny, no one in their right mind would pay that for two lumps of metal - how much were they really?"
Me: "about 25 quid?"

What could go wrong?

Anyway, next question - Archetypes of Velocity A23s?
cheers

Archetype, the new A 23 tubeless ready are a pain.. .no tape fits properly (have not tried Stan's)... OK if you go tubeless, otherwise Archetype all the way

What do you think of the Pacenti SL23 rims?

I bought a pair about five years ago(older version) and despite only having done about 4000 miles the rear has some hair line cracks coming from the spoke holes and the free wheel mechanism makes a right racket.
Certainly wouldn't buy another pair.

I think they are ugly... :mrgreen:
Seriously, I don't know, I have never had the chance to build one... they are a bit pricier and they look quite horrid, so I am a bit put off... the weight saving is very marginal and the extra mm... well, people who have ridden the 25 mm HED+ say they are exactly the same as the 23... so a 24 mm rim is not likely to cause a stir

the SL23 is the same width internally as the Archetype and A23. The extra mm is to try to make the rim more aero buy giving a flater rim to tyre transition. Pretty pointless really.

No they were built at a bike shop by a wheel builder I have used before with no problems.

I have the DA9000 in the spoke count you mention laced up to the Archetypes.

Fantastic wheels built by a builder not a million miles away from this post.

I find that they roll better than my chris king r45's on gigantex rims and I am generally not out rolled on descents on the club rides I partake in (freewheeling).

They are also bomb proof - done 3,000 miles on them this year and still they run true. Can't remember what spokes were used but I am sure ugo will jump in and remind me...

Do it. You won't be disappointed.

Cracked flanges in Shimano hubs are very very rare, as the shells are forged, rather than simply CNC machined, like Hope or DT Swiss for instance. This adds strengths and improve fatigue. Any chance they were tensioned too high?
I have seen wheels tensioned at 1600-1700 N from very respectable builders... and whilst the wheels perform well, the flange suffers a bit

My instincts also say tension too high if the crack is on the DS rear.

Hubs will not make anyone faster. I roll quicker down a hill than most in the club but it not down to the hubs I use it is for other reasons like as I do not hit the brakes.

CK hubs, Hope hubs, DA hubs all waste a 1W or so at 30 mph maybe less they will not make you go faster. The extra drag on hope hubs are the seals which you want trust me.

I havn't got anything to measure the tension but from experience I wouldn't say they feel over tight.

Depends what you are referencing doesn't it. If you do not have a calibrated gauge you have no idea what the tension is. Even calibrated gauges will differ on the results. My DT Swiss gauge gives tension results to my Sapim Gauge, which is why a load cell and rig is in the works so I can make my own conversion charts for each gauge I have and the other I have not bought yet.

Referencing 40 years of experience.
I agree spoke tension is the most obvious cause but they are not obviously tight.

I was tempted by the Dura Ace hubs when I saw how 'cheap' they are at Evans. I love the concept of the digital click adjustment system, but at £235 they are ~£190 more expensive than a pair 105 hubs. £190 for oversized aluminium axles and a titanium freehub?! The rear hub alone costs as much as the entire 105/Archetype wheelset I'm building. As much as I lust after these hubs it would be insanity to buy them.

Another thing that put me off - while it may be unlikely that I'd ever need to replace the entire axle assembly, the replacement axle kit for the £160 rear hub costs £120. :shock:

I think the 105 hubs are a bargain. Make for great winter wheels... Don't quite have the "bling" factor that some people like though.

Couldn't agree more, it's madness, but sometimes sensible financial decisions and cycling just aren't compatible.

I also have the 105 hubs as well sitting under my desk along with some Ambrosio Excellights. The hubs were less than £45 from Ribble on one of their 10% off promotions and the Excellights were £25 each from Hubjub. Even adding in the spokes, the whole wheelset will have cost me less than the DA rear hub.
cheers
