Campagnolo 11spd Cassette on Ksyrium SLR - Spacer ?
Moderator: robbosmans
I need to install a Campagnolo 11spd cassette on a new set of Ksyrium SLR. In the user guide, they indicate that a spacer is needed when installing a Campy 11spd cassette. Strange thing is that they don't include the spacer. I've read online that the new Campagnolo cassette body doesn't require the spacer for the Campy 11spd cassette. Anyone can confirm. Thanks.
Yes...need spacer.

Thanks em3.
My situation is getting more confusing. Talked to technical support @ Chain Reaction Cycles (where wheelset was purchased) and they said the new Mavic Campagnolo freehub cassette body doesn't need a spacer for 11spd cassettes !!!
I guess I will need to call Mavic.

In terms of fitting the cassette to the freehub, both 10 and 11-speed Campy fit just the same. ie the lockring will tighten up either OK.
There is a slight difference in that the 11-spd big sprocket is dished about 1mm closer to the wheel, so more attention needs to be paid to the inner RD stop to make sure there is no interference. This is not a new situation for Campy, on some of my wheels, a 10-spd setup can already be very close when on the big sprocket. It depends largely on the spoke type and pattern.
My old Ksyium SL's have straight pull bladed spokes on the DS and there is loads of room for an 11-speed cassette.
In your case, I'd be setting it up with the cassette without spacer and just checking carefully the RD stop setting and cage clearance. Just know that it can be close.
I have a second reason for this advice. Some frames have very tight clearance at the dropout. I discovered this on my older BMC SLC01, when there was binding the first time I installed a wheel with 11-speed cassette. The dropout was binding on the lockring. I then discovered that the 11-spd lockring was about 2.5mm thicker than the old one. Swapping with a 10-spd lockring fixed the problem.
So, pushing the cassette 0.55 mm further towards the dropout with a spacer could also cause a problem. Which is why I'd try it without first.

There's sometimes a buggy.
How many drivers does a buggy have?
One.
So let's just say I'm drivin' this buggy...
and if you fix your attitude you can ride along with me.

Use your brain. Bikerjulio is spot-on.
I believe the Mavic freehub bodies have not changed in design - only in name. When Campag went 11 speed, Mavic just re-named their Campag freehub body 'ED11', but it is the exact same item as ED-10. And with ED-11 they supply the 11 speed spacer.

You're talking about new Ksyriums, right? No spaced is required for Campy 11sp cassettes. Early on there was an issue for about a half a production run and, depending on which cassette you were running, it could be too close to the flange. The solution was the .55mm spacer. But that only affected a relatively few users. With a new wheel, no spacer.
