Scott H.wrote a review of Lizard Skins Neoprene Chainstay Protector on February 2, 2018
I missed the specs on the difference between sizes. Since I have a full size mountain bike, I figured the large would fit. It's too big and I should have gotten the medium. The cost doesn't justify sending it back so I'm gonna see if the wife can sew a seam in it where it will fit snug. The cover itself will work as advertised so I'll give it 5 stars. I guess some bikes have som huge chain stay tubes.
