Driveline 53T Bash Guard, Chainring Guard, Chain Cover, BCD130mm CNC (Black)

Finally, my bike chain doesn't come off, it kept coming off in the front 1-3x when ever i ride, i put this in the inner front star, and it works perfectly, i took away one star because the screws that came with it were to long, local. bike shop wanted $15 for 5 new shorter screws, i opted to go to home depot and purchase 10 spacers to make the included screws work , overall this solved my problem

Very nice piece. Diameter is spot on to fit perfectly within the tight tolerances between teeth height and gap to derailleur. Includes longer bolts, sleeves, and spacers to position it exactly where it should be laterally as well.
