Campy cassette lockring 11t??

[skiezo]

So I am converting my rides from 10 speed to 11 speed. Most of my 10s cassettes have a 12 tooth lower cog. The 11s stuff I have has a 11 tooth cog.
I am guessing the 12T lockring will not work on a 11T cog,Is that correct?
I need to get a lockring for 11T?

That is correct. You need a 11t lock ring. Make sure it is for 11 spd only. I'm not sure if there is a difference but I suggest getting the 11 spd one to be safe.

Yes. 11 speed lock rings are marked "11 speed only". I haven't tried to use a 10 speed lock ring on an 11 speed cassette. Pretty sure all 11 speed Campagnolo cassettes come with lock rings.

Yep, all Campy cassettes come with lockrings. :)

I just switched from an 11 to 12t small cog and I needed to find a 12t King lockring. If you need an 11t Chris King R45 lockring, let me know!

I just had my LBS order me a miche 11s/11t lockring. It is about 1/2 the price of the campy brand.

I have plenty of spare 11sp 11t Campy lockrings if you need more.

I have plenty of spare 11sp 11t Campy lockrings if you need more.

Thanks, I may need a few more. If I do ill be in touch.

11s ones are smaller, otherwise the chain will hit it and skip. You CAN use a 11s lockring with a 12t cog but not vice versa.
