I think i might be going crazy or this may have been discussed before.. but I just got upgraded to the new 11-speed dura ace and I put my Enve wheelset on that still has a campy cassette and the shifting works really well! Am I missing something?

No, you're not going crazy.

The spacing between cogs on Shimano/SRAM and Campagnolo has always been the same if the cassette is the same speed.

Back in 10spd world, you could have used a Shimano/SRAM or Campagnolo 10-spd cassette with any 10-spd drivetrain system. How do you think those neutral support vehicles could just throw on any wheel and make it work? (Before the transitions of 11-spd started taking place)

The differences are only in the freehub splines, and the compatibility of shifter-to-derailleur. In the analog, there wasn't any noticeable incompatibility of shifter-to-front-derailleur, but now that Shimano and Campagnolo have both gone electronic, the incompatibilities are regardless of derailleur.

Well the spacing is not the same, but the difference is so insignificant that they are interchangeable without any problems.

The difference in that range is actually so insignificant that you can use a 10 speed cassette with 11 speed shifters by limiting out the last gear.

So, is it also possible to use 10 speed shifters on a 11 speed cassette?
Anyone tried that?

10 speed cassettes spacing are not the same Shimano/SRAM = 3.95mm, Campagnolo 4.12mm e.g. Shimano/SRAM cassette on a Campag drivetrain
Center the chain exactly on 5th cog (best case) then shift to 10th cog the .17mm difference in spacing accumulates to .85mm overshift or about 22% error
center the chain on the 1st cog and it would over shift by 1.53mm 40% out, might shift but far from ideal.
Shimano/Campag 11 speed cassette spacing is close enough not to make any difference.

In a German forum a guy measured the difference in spacing. It was 0.02mm... so your assumption is right! :thumbup:

I did notice a little turbulence in the middle of the cassette.

My Dura-ace 11 speed cassette is creaking like no bodies business, so I tested an 11 speed campy wheel on my Red22, works fine. If it works on SRAM it'll work in Di2.

@nismosr yes, test rode a 12-25 d/a 9000 on a full super record build today, was flawless barring one thing -the chain was catching the shift pins when in the small/small combo, though I think that may have been more a product of the wheel change/cassette position.

Did / can someone measure the cablepull on sram 11 speed shifters?

What about wheel dishing? My zipp 303 was sent back to the factory for 11 speed hub upgrade because they need to redish the wheels, and I have to buy a new Campy free hub body to work with the reddished wheel.

Don't understand this one at all.

Campy 11 spd cassettes work on 9 and 10spd freehubs just fine.

I have a Proton wheelset bought in 2002. An 11spd cassette jams into the spokes: it plain doesn't fit. I suspect I need a new freehub.

How about a new brain?

A Little screwdriver would do perhaps?

Ciao, ;)
