Front rail attachment 

Since 2014 all Ass Savers attach to the front saddle rails only, ahead of the seat post attachment. The advantage with this solution is that saddles are more uniform in this area and we can therefore provide a proper fit to a much wider range of saddles. Attaching only to the front rails makes the Ass Saver self-centering. If you accidentally kick it without noticing, it will strive to regain its centered position. This is one of the key innovations in saddle mudguard technology and is therefore protected under a pending patent No. SE PRV 1750201-4


Using origami principles, the patent-pending FLIP-TIP™ technology allows you to securely fasten the Ass Saver to the saddle with a simple flip of the tip, just like a cycling cap. To unlock, just flip the tip back down and pull backward. Carbon rails The FLIP-TIP® technology is fully compatible with all types of carbon saddle rails.

Saddlebag compatibility 

The new Ass Saver is a lot easier to install with a saddle bag than previous models. While we can't guarantee a perfect fit with all saddle bags, great improvements have been made with considerably less interference as a result.


The secret to transforming a flat piece of plastic into a functioning product lies in the pre-folding prior to use. All the scoring lines have been carefully engineered to achieve locking mechanisms, self-centering abilities, spring loading, and material endurance. Please take the time to properly read the instructions/see the instruction video to ensure the best performance.

Money wasted !

Lost the fender within 15mins of my first ride with the fender. Not suitable for Indian conditions, it's easily to be picked up by other's.

Ass Saver fender

The fender looks good but lost it within 15 mins of my first ride with Ass Savef fender ! The locking system is not so efficient and also it’s easy for others to remove it when one is on the bike and one will not even know.
