I desperately needed a skirt guard for the summer. I found this one which had a good rating from previous purchasers. The guard is so easy to fit to the bike, light and will not mark your bike and actually looks good. You don't need tools, or instructions (which weren't included anyway). I was able to fit this in a matter of minutes by just looking at the picture on Amazon. I was so pleased, now I can ride my bike in the summer, if we get one this year, in a skirt without worry. I would recommend this to anyone.
