11 Speed Cassette Spacing
 
Someone suggested that 11 speed cog spacing is identical between Campy and Shimano. Does anyone have any good knowledge of that?
I have 11 speed wheels but they are Campy splined.

They are not identical.

Lou's answer fits my understanding, BUT

I have seen (widely) the opinion expressed that the difference is so
small as to be functionally irrelevant.

See, for example, Lennard Zinn's answer to the second question he
https://www.velonews.com/2013/09/tec...1-speed_301392


Of course, I've seen /some/ say the same was true for 10-speed. The
/consensus/ seems to be that this is balderdash.

"Campagnolo 11 speed cassettes have just slightly different sprocket thickness and spacing, compared to Shimano, so they can be mixed with Shimano 11 speed shifters and derailleurs (and vice versa), with index shifting working good. Provided that appropriate freehub body is used: Campagnolo and Shimano cassettes can’t fit each other’s freehubs – Campy with Campy, Shimano with Shimano.

With 11 speeds there is another exception: it is the only case where Shimano standards for road and MTB differ. For all the other standards, MTB and road cassette is just a marketing term, explaining the number of teeth bigger sprockets have and the difference in sprocket teeth numbers between adjacent sprockets, but with 11 speeds, cassettes really differ. 11 speed road has a longer freehub body, while MTB 11 speed cassette fits 8-9-10 speed freehub. However, sprockets, except the largest one, can be mixed and matched.

Update of summer 2018: Shimano introduced new Hyperglide+ cassette standard.. These come as 11 and 12 speed cassettes. They require a special freehub body (with different spline design called “Micro Spline“), as well as a special Hyperglide+ chain. The same chain is used for both 11 and 12 speeds, but works only with Hyperglide+ cassettes. Also, derailleurs and shifters of other standards won’t work. Smallest sprocket has 10 teeth."

You bought 11 speed equipment, set it up and adjusted it meticulously and then use a Shimano cassette on a Campy system or vice versa. That is beyond me. Sure can be made to shift but not without noise in all gears.

Well, I THINK I bought a set of Chinese 11 speed Shimano hubs that I THINK are interchangeable freehubs. Hopefully they will mount on my carbon clinchers with no problem and then I can put a 11-32 and GS derailleur on.

If you do not want to dothe adjustment each time you swap them, just use
a friction shifter.
