MRP 1x V3 CS Chainguide - 28-36T, E-Mount, Black

It's not a bad chain guide. It's made of some type of plastic and it's light but be careful when tightening the screws. I didn't think I was close to over torquing the base plate but it snapped as I was just getting it snug. The other screw seems to be holding it on well enough so it should still do what it's supposed to.
