I have ultegra 11 speed myself

Better value for money you will get nowhere.

This is one awesome groupset.

 

all shimano freebody mavic wheels can take 11 speed.

 

Bb will be no problem

 

Go for it!!!

Be careful. Not all the Mavic wheels are 11s compatible. You  may need to order a new freebody from Mavic

Depends on the age of the wheels

actually you're right> i thought there was a running changed but it appears they all are:

Dear Lennard,

I was reading the comments in a recent column about a rider switching from 10- to 11-speed when his shifter broke. This leads me to the question. Which recent 10-speed road wheels are compatible with SRAM/Shimano 11-speed? I know that’s a large topic, but I was thinking primarily of popular, high-end carbon wheels like Zipp Firecrests, Mavic Ksyriums/Cosmics, Reynolds, and Bontrager.

Dear Glen,

I don’t know if Mavic had a crystal ball years ago, but Mavic 9/10-speed wheels are 11-speed compatible. That’s because its Shimano/SRAM-compatible freehub bodies have for many years been wider that those of other hub manufacturers, and in order to put a 9/10-speed cassette on one, you were required to put a (supplied) spacer behind the cogs. This was amazing foresight or plain old dumb luck.

As far as I know, no other 10-speed Shimano/SRAM-compatible freehub bodies are 11-speed compatible without modification (as I did here).

However, all Campagnolo-compatible 9/10-speed freehub bodies also are compatible with Campagnolo 11-speed cassettes. And, as I’ve said before, there is 100 percent shifting compatibility between 11-speed cassettes. In other words, Shimano, SRAM, and Campagnolo 11-speed cassettes work just fine on each others’ drivetrains. So, one way to use an old 10-speed wheel with an 11-speed drivetrain is to install a Campagnolo freehub body and Campagnolo 11-speed cassette on it.

I should also add that Chris King R45 hubs are also 11speed compatible by removal of an aluminium spacer.
