I just checked the 12t-30 casette I took the lock ring off...you are right...I didn`t realize it was a 12t lock ring I used.
That is a relief. Thank you for helping me.
I do not know if the original was aluminum or not. It is incredibly lightweight and I think it is plastic to be honest, but the original poster said aluminum. What I will do is order a few replacement shimano 6700 11t lock rings. Then try again. Do you really put 40nm into these? It doesn`t seem possible. I should invest in a digital torque wrench maybe? Do you use the stock lock rings on your bikes? Or use some sort of aftermarket steel one? I appreciate you helping me. Thank you.
Great, glad it answered your problem.
As to the composition of the lockring, I'm certain it isn't plastic and surprised if it's aluminum. All of the ones I use come with the cassettes, either Shimano or Campy, and they have all been steel. Yes, I do torque these steel lockrings to 40 N-m and I do have a torque wrench. It's too bad about your bike shop because most of them have a drawer full of surplus lockrings and will happily give you a couple.
