We like Fat Butts and we cannot lie.

  • The original wide saddle guard - designed for fatbikes or just a wider load!
  • Prevents 'soggy arse syndrome'.
  • Prevents the top of your seat post from getting clogged up.
  • Discreet but very effective - weighs just 45g!
  • No fasteners required! Our simple, clever design is quick to fit and secure once in place!
  • Compatible with most standard double steel rail saddles that don't have any daft plastic moulded bits in the way!
  • Easy to clean as it's flexible and opens flat. Simply wipe it and you're done.

For the ultimate in muck protection for your fatbike, couple this with our Fat Face Fender and Fat Gut Fender!

Fat Butt Fender fitting instructions:


    1. Lightly squeeze the fender along the crease lines to form it into shape. Make sure it stays wider than the tyre width!


    2. Slot the 'wings' through the back of the saddle rails, then reach in and pull the hanger downwards to clip onto the bottom rails. It should look like this...



    3. Square the shape up and you're good to go!
