Whether it’s the weekly group ride or the “A” race of your season, don’t let a dropped chain leave you panicked, greasy, and desperately chasing. The new ARg offers 25 grams of vital insurance for every 1x all-road or gravel bike. It boasts a streamlined alloy upper guide with 8mm of chainline adjustment and a nitrile rubber o-ring to eliminate noise. With its compact design, the ARg is so lightweight and quiet that you’ll barely even notice it’s there.
