Ass Saver Rear Fender

Not the longest rear fender out there, but the Swedish made, totally recyclable Ass Saver Rear Fender is easy on and easy off and does a fine job of keeping your butt (sorry, ass) dry. Small enough / flat enough to stash in a top tube frame bag.    Installation is a breeze, you just jam the fender under the saddle between the rails and flip a little tab.  If that sounds complicated, there are directions printed on the underside of the fender that walk you through the install.  It's about a 12 second process.  Our favorite thing about these fenders, besides the graphics options, is that they don't wiggle around and spin like every fender that mounts to your seatpost.  So you can ride rough stuff and not worry about your fender spinning and attacking you.

The "Regular" are designed to work on tires up to 35mm wide, but we reckon you can stretch that to 2.1".

And the "Big" is said to work with tires 30-50mm, but we would say you can stretch that too, and be pretty well covered up to 2.4".
