incredible

28 teeth is exactly what i needed, it fits perfectly on the 64bcd, and with the way that its shaped it brings the teeth closer to the center line of the rear cassette. I put an 11-42 cassette out back, and now I can climb anything!

Great Product

NSB is my go-to chain ring. They last twice as long as other products, perform well, and look good. Easy to install with the threads milled directly into the ring.
