It is true. It happened to a 7900 DA I had.

Right down the middle of the axle the metal bent and twist and snapped at a nice 30+mph training sprint.
Got it warrantied but I looked around and other people had the same problem.

We have had three people in my area (southeastern Virginia, USA) with broken crankarms. Split down the seam.

Another component that is better in the case of Campagnolo is its Super Record crankset. Its cult bearings make it rotate so smoothly that I doubt DA comes even close. Both SR and DA are similar in terms of stiffness if I remember well.

Which actually is not that important. The last DA should be even stiffer as they have improved the effective moment of inertia by enlarging the height above what usually is the neutral axis and keeping the distance to the lower panel to avoid instability (buckling) phenomena in the compressed area of the crank arm.

Again, so much fuss, 0 gains.

Super Record is the best because it's called "super." Case closed.

Oh and it looks way cooler than Steve Ray and the other stupid names that make up SRAM. DA91XX is cool because of the "tron" factor but forget about Ultegra, every time I see it I'm like "really? DA isn't that expensive"

Yes, I kind of agree. Why is that? Why is Record or even Chorus so much more appealing on a bike than Ultegra?

Ultegra is a bit porky but is functionally very good.

It might suffer from association and the fact it's everywhere ... by association I mean the fact it's relatively cheap and therefore features on a lot of mid range 8.5kg ish bikes that are downright depressing for us WWs when you see them lined up in a high street shop (e.g. Evans/CycleSurgery here in the UK).

My impression is by contrast anyone - in the far smaller population - with Record or Chorus is more likely to have a top-end frame, and other well chosen parts, wheels etc

And record offers no benefit over chorus, for yet another $500.

Campagnolo:
- Better hood ergonomics (mechanical)
- Differential braking (single pivot rear, dual pivot front)
- Stiffer cranks
- Better wheels hands down (triplet, excellent hubs)
- Way better looking

Don't waste money on Record or Super Record. Chorus is only marginally heavier than them, and should actually last longer... internals are made of better wearing parts as are the consumables (cassette, chain).

I have two full Chorus 2016 groupsets on two bikes, three campy wheelsets (Zonda C17, Shamal Ultra C17 and Shamal Ultra 2017)... totally invested, and wouldn't switch for love nor money. I recently bought two new bikes from Canyon knowing full well Ultegra and the wheels would be coming straight off and going on eBay...
It's ALL about the bike.

Which church do you belong to? SRAM, Campagnolo, Shimano -- they're all great. It really depends on which religion you subscribe to.

stupid question....I got a XR3 with the new ultegra set, changed the Racing 7 to Zonda wheels.
The bike is still new, pedals aren't even installed and I'm having second thought about changing it to Chorus set.

The LBS I got the bike from is unwilling to change the Zonda shimano hub wheels for the Zonda Camp hub wheels even if I buy the whole Chorus set from them, he said, just change the hub.

Is there any difference between them besides the hub? straight forward swap for around US70?

The rear freehub is the only difference.

So amidst inevitable comparison on features and styling who can comment knowledgeably on the point about freehub gouging and bearings?

Well, on that last point... the Shimano freehub design comes from long ago when freehub carriers were made of steel (like, duh). This was a time before the marketing push for ever lighter weight. That freehub is fine if fabricated in steel, not so great if fabbed in alloy. I recall some iteration of D-A moving to a deeper spline pattern but Shimano had to back off on that because people whined about incompatibility issues.

Campag either by luck or judgement made an early design decision for deeper splines that have more material to resist sprocket gouging.

No point in swapping

chorus will just shift as well with 11s ultegra cassette-chain as with 11s campag.

stick with shimano freehub body.

Will have greater access to cassette ranges, and will be easier to resell the wheels later.
