I have two of the NSB M8000 fit chainrings, a 34T and a 36T. Both are very nice and work as well or better than other brands I`ve tried of this type narrow-wide tooth design. What I really like and where NSB really nailed it is with the bling factor and having something unique for my high end bikes. I love the minimalist design and lettering. Shipping was surprisingly fast from Canada to Washington State.
I recommend this product
