Chain ring is brand new from a crank set where the chain rings were changed immediately upon purchase and are un-ridden. This is a 46 tooth, X-Glide SRAM chaining, built for 11 speeds and built for a double chain ring set up as the outer chain ring. It uses four regular chain bolts, and a hidden chain ring bolt behind the crank arm which is included. I have a 36 tooth chainring listed for sale on eBay which you can purchase separately to pair with this if you want.
