Review on 🔩 Enhanced GRK RSS 185 8 Inch Structural Package by Steve Cooper

I have no idea the 'structural' strength of these items as I'm not sure which test actually proves their strength. But in the field it seems to be a very well made and easy to use shutter. I've ridden about 50-60 3 1/8" discs and none have even suggested taking the head off. They are very easy to work with in pressure treated 2x or 4x. Due to their composition (hardened steel). They have those Strength of a nail and the usefulness of a screw, but not ceramic coated screws which, under the right conditions, will easily snap in half.
