Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them.

is it still a problem?

do the 9000 users like the 9000?

I saw that there as a problem with the original 9000 shifters, but but it has been solved. I have not seen the same problem with 6800 shifters.

DA 9001 shifters replaced DA 9000 shifters. The cable cover of the 9001 was revised to reflect Ultegra 6800.
Never really clear if the change in the cable cover affected cable life...could even be the early DA 9000 cables which was the root cause of reported cable breakage.
I installed DA 9001 on my favorite road bike and rode it for 2 weeks and then reinstalled Campy. To me there is no comparison in ergonomics of Campy compared to new DA 9000/9001....Campy shifters are more friendly to the hand on a number of levels.

Personally if you are ok with the sharp edges of DA shifter and the hard durometer of the hoods, go for it. I don't see the cable breakage thing as that big a deal. You may want to keep an eye on cable fraying up near the cable head where it takes a sharp bend inside the shifter.

Same here, though my DA bike is still fairly low on mileage, maybe 1k-ish at this point.

Campag: what sharp edges are you talking about?

he's talking about the pivot area behind the lever.

Actually all over DA 9000 shifters....on top in front, right behind the lever underneath where the first knuckle resides...even the large brake/shift lever.
Night and day compared to Campy in terms of ergonomics. But if you ride DA 9000 and it feels good, stick with it because shifting is fantastic.

My set of DA9000 might be from a newer production run than yours so some of the hard edges may have been smoothed. I have not felt any sharp edges and I made a point of trying after reading your posts. The hood shape may be an issue for some, either DA or Campy. Having also tried Record, my reaction is that day and night must be fairly similar where you live. Don't interpret this as a knock on you because comfort is personal and my evaluation only reflects my experiences.

I saw a post on Bike Radar that someone snapped a 6800 cable with 2500 miles on it. So it appears this has not been fixed by Shimano yet. Can't say I'm thrilled about this as someone who is about to install 5800 on my bike with the new polymer coated cables. Worst case I'll just replace the rear cable myself every 6 months (hopefully) before it snaps. I had 9000 cables on my 5700 setup and the RD cable was badly frayed at 6 months.

I have about 2,000 miles on my DA 9000 with no cable problems. I find that my hands go numb faster using this set much faster than my 6700. Other than that I love it.

The hoods are narrower on the new 11sp shifters. I think it's a step backwards but I'm hoping someone comes out with a wider aftermarket rubber hood cover.

My DA9000 has over 3400 miles so far. I will check for any fraying and report back if there is any.

Interesting timing...I just snapped my rear derailleur cable this week on my 10spd Ultegra (not sure of exact model), also after 2500 miles or so. My previous 105 10speed had no problems at noticably more mileage than that before I upgraded. Anyone heard of Ultegra parts having a similar problem to this?

It isn't a knock on me, more rather a knock on you.
Quite right, I would say you reflect the norm, including the rather dim Shimano engineers that created the shifter ergos for Ultegra 6800 and DA 9000.
I had the newest shifters btw, DA 9001.
So, in summary, if the bell curve of owners is like you, new DA 9000 is fine. This also comports with all the articles that lavish praise on new DA 9000 and really why I built up a bike with it. I wanted to find out just how new DA stacked up with Campy and I did.

If focused on ergonomics, there is absolutely no comparison with Campy on many levels and has nothing to do which how each groupset shifts. New DA shifts brilliantly in fact...just excellent shifting.

Yes, comfort is personal...absolutely true. And some are more perceptive than others, in fact greatly. Lance Armstrong and Eddy Merckx could feel a 1mm cockpit change. The rest of the riding public, or most can't. A lot of guys can't feel 5mm and don't know a good fit from a bad one.

There is a reason why many prefer Campy but I would say perhaps the majority wouldn't get it. Some will ride Campy and even not know why they prefer it, they just do on a subconscious level. Btw, this is a common theme in automotive focus groups and has to do with how the brain processes things in aggregate for non critical thinking people in particular. But when my first knuckle was getting scraped with fingers wrapped around the hoods when out of the saddle, with a knife edge metal plate 'that moves laterally to perform the shift' on DA 9000 just behind the shift lever up high under the shifter body...to me the Shimano engineer responsible should be fired because he's an idiot. This should have been executed differently. Many spend a lot of time out of the saddle when climbing and this is a common position and unforgivable really and neither Campy or Sram have that deficit. Of course they shouldn't, as it is a 'fundamental'...no sharp edges where the hand can interface with the shifter...especially in common positions. But there are many more instances of sub standard ergonomics on new Shimano shifters. If you wear gloves or maybe work construction for a living with callouses all over your hands, you may not notice. For the rest, thank goodness the Campy engineers sweat these details including the variable compliant hood covers verses single thickness hoods on DA which feel like grabbing a wood fence.

I went and test rode a 6000 MSRP Bianchi Infinito CV with 11 speed Chorus TODAY. I own three road bikes. A Jamis Aurora with 9 speed Tiagra, a Domane 4.5 with 6700 Ultegra and a Roubaix SL2 with 4600 Tiagra. I honestly don't understand why people rave about Campy ergonomics. #1 , the thumb shifter is only in great position if you ride in the drops. Otherwise, to shift, you have to move your hand on the hoods. #2 , too many damn clicks on the front derailleur. Really, why? Shape of the hoods is OK for my hands, a bit too thin.

I would take the 6700 Ultegra over 2014 Chorus any day.

I like the idea of Campy and what the name stands for, but I don't think I can own one day to day unless it is the new EPS drivetrains.

Perhaps that is the issue here, that you are an unusually soft and effeminate individual. I've ridden all brands of shifters and they feel fine, though I do have a slight preference between shapes. I've actually never heard a cyclist complain about shifter comfort nearly as much as you manage.

I see you ride a CAAD9. I would say you are superman but you are no man of steel. Why would you have any preference for shifter shape? Didn't you lose a few fingers in a garbage disposal?

What does a CAAD9 have to do with anything? It seems the deeper you go into the interminable maze of shifter shape ratiocination, the more the dark mists confuse the direction of your sentences.

But it could just be me.

In your simple world, they are the same. The reality is, for the discriminating person they are vastly different. Because they are vastly different, a given discriminating rider will have a preference....as in my case. But not a simple man without the ability to differentiate. Does that resonate with your simple view?
To use an analogy, in your world, a Honda is a the same as a BMW or a Porsche. They are all cars and get you down the road. In mine, they are vastly different. In fact, I would bet a fair amount of money you don't own a higher end performance car and it may have nothing to do with your economics. You literally don't see the cost/benefit. Many feel this way in fact. But for the discriminating driver, there is a pronounced difference.

My career has been design. You maybe a plumber or an accountant or maybe a bartender. We are not the same. When I built and rode DA9000, I saw the possibilities which weren't met. This is on the heels of Campy Ultrashift being out since 2009 to benchmark from. DA7900 was a disaster on almost every level. You probably didn't even notice. You are blind to design. For you a shifter hood is a knob and if the lever shifts the gears and bike slows down when applying the brake, all you can ask for. So no, we aren't even on the same planet when it comes to bikes or groupsets. Honestly, our differences are the reason for the discord on this forum. But good to acknowledge and yes we are all different and will have different preferences and some like yourself will only have a muted preference...in your case hood shape...because you can't tell the difference in perhaps 20 attributes that make up groupset performance.

There may even be some small common ground. Because you are such a simple man, you may feel that electric shifting is unnecessary and if you have tried it, you may even prefer mechanical shifting. We would agree there. In spite of our vastly different perspective as I think about things in the context of design that you never even considered, there may even be some common ground.
I hope that makes sense.

PS: for an illustration of one of many faults with new DA 9000/Ultegra 6800...they are basically identical for quite a difference in cost to the consumer but not to manufacture, below shows something that would be fundamental to any designer...no sharp edges where the hands interface with the shifters.
You see, Jiggle to you, it may not matter...but there is or should be a reason different radii are chosen for example for lever length and shape...or durometer of rubber for the hoods for example. So it comes down to attention to detail you can't discern but others can. Kind of like a blind man (you) not being able to read text on a page....or if you can read say in this instance, you still don't comprehend it. For instance, in the case of Campy the shifter lever is indented for simple 'registration' of the index finger for quick location of the lever. This is an ergonomic feature and was readily apparent to me the first time I rode 9000. You wouldn't notice it however. Shimano doesn't have that feature....the lever is flat and replete with no radii around its edges. It is less friendly to the hand and the smaller rearward shift lever is harder to discriminate from the brake lever.

Below captures one of the biggest failings. I wonder how many of the engineers were laughing at the design when they went into production in fact.
I have worked with many Japanese engineers and they have a funny sense of humor. Maybe an inside joke at Shimano. Shimano for all their technical proficiency, is utterly clueless about the human element of interaction aka ergonomics...or care less about it.
Also included a comparative pic of Campy Ultrashift. Notice the indented shifter lever and completely devoid of any sharp edges around the entire shifter. Hood cover differences are literally night and day. Shimano is a single thickness and Campy's hoods have suspension (egg crating) for much greater compliancy. The 'aesthetics' of Campy are often mentioned because this appeals to the eye of some. But honestly, the aesthetics is effect and not the cause. Form begets function when it comes to human interaction. It is the design that separates the two groupsets resulting in one looking better which may even be incidental to some but a by-product of greater attention to detail which the Italians have mastered.
