Installing Ultegra 10sp Cassette - Spacer Question

I am about to install a 10 speed Shimano Ultegra casette on an Ultegra hub.
The cassette did not come with a 1mm spacer, but I have read that I needed to install a 1mm spacer first.
Is this true? If so, what kind of spacer do I need? I have a couple 1mm freewheel spacers laying around that I have used behind older 5 and 6 speed freewheels, will that work?
What is the purpose of the 1mm spacer?

Any help is much appreciated!

i had that issue with an ultegra cassette on a bontreger hub. you will know when you need it. in my case the cassette hit the spokes without it. i just found the thinnest spacer i had and it worked great.

Purpose of the 1mm spacer is either to allow proper rotation of the freehub or to allow proper compression of the cassette, since 10 speed cassettes are narrower in width than the 8/9 shimano cassettes. Your 10 speed cassette should come with the necessary spacer.

i guess we may be talking about two different things. are you referring to the thin spacer between the lock ring and cassette?

i totally missed the 10 speed reference. when installing a brand new 9spd ultegra on my bontreger wheel i had to use a spacer behind the cassette. without it, the reassess in the cassette went over the stepped portion of the hub and hit the spokes. i added a thin spacer to prevent the cassette from getting over the stepped freehub body and all was good. i am not sure if 10spd is the same

You might be, the OP is not. The "washer" between the lockring and the smallest cog is not 1mm and is irrelevant to this discussion. The *1.1mm" spacer the OP is talking about is exactly as I said. His ultegra wheelset is not your bontrager wheel.

So, I do need to place a 1mm spacer on the freehub body before I place on any of the cogs? My question is: is this is a special 1mm spacer?
Last night I placed a 1mm freewheel spacer on and then installed the cogset. I torqued down the lockring but the cassette was not sitting properly. I checked the orientation of the cogs and they were correct. I then discovered that the 1mm spacer had gotten mangled up behind the set of the 3 largest cogs. That spacer is either not needed or it was the wrong kind of spacer. I need help!

If it matters, I am using both a 6600 Ultegra cassette and hub.

Freewheel spacers will not work. The soft AL kind you are using will not withstand the pressure from the lockring compressing the cassette - as you have found out. Really, anything that is metal, the right inner diameter that is 1.1mm thick and uncompressible will work. Your LBS should have a gazilion of these lying around.

Thanks operator! I knew I was going to have to end up going to the LBS eventually, I just like to have a good idea of what my problem is before I go.
I really appreciate your help!

This is one thing I like about SRAM cassettes. They seem to be made in a way that doesn't need the spacer, no matter which hub.

Are you using a 6600 Ultegra wheelset, or just the hub? IIRC, those wheelsets do not require the spacer as they have a special 10 speed only freehub with taller splines. The taller splines would prevent installing the standard Shimano spacer.

I am using the 6600 Ultegra hubs laced to Mavic Open Pros. Yes, what I have read is that the 10-speed only Shimano Ultegra and Dura Ace wheelsets do not need the spacer, as they have 10-speed only freehubs. But the 6600 Ultegra hubs are compatible with 8,9, and 10 speed cassettes and so require the spacer underneath the cassette for 10 speed applications.

Really? What problems did you have? I've been on my 11-28 for 2 years now with minimal wear and the only complaint is that it makes a little more noise compared to my Ultegra 11-25... although I have the missing tooth design which has been reported to make more noise than others.
