Race Face Cinch Shimano Steel Chainring Black, 34t, 12-Speed

"What Our Gearhead® Experts Are Saying:""This is the chainring you buy when you're done replacing chainrings. Steel wears slower than aluminum, and at this price point it's an easy decision. The Cinch interface makes swapping tooth counts fast if you want to tune your gearing for different terrain, and NW tooth profiling does real work keeping your 12-speed chain on the ring through rough stuff. If you're already running Cinch cranks and moving to 12-speed Shimano, this is the most sensible path forward.""Most components get replaced because they wear out. The Race Face 1x Chainring Cinch Direct Mount in steel is the answer to that problem. Stamped from real steel rather than aluminum, it holds its tooth profile longer and keeps your 12-speed Shimano drivetrain shifting cleanly through more miles than most riders will ever put on it. The Cinch direct mount interface makes it fast to install and easy to swap if you want to change tooth counts for a different trail or a different season. NW tooth profiling keeps your chain seated through rough, choppy terrain where a lesser ring would start dropping it. For riders who want to build a 12-speed drivetrain around the cranks they already own, this ring removes every reason to buy something else."
