For those of you who have been commuting on their bikes regularly, riding in the rain can be a really fun and fulfilling experience. But one thing that tends to be a bit of a bummer (pardon the pun), is having a wet backside at the end of it all. I mean, imagine heading out to meet your friends for a casual get-together and you end up at the venue with a trail of dirt on your bum. Not only is that embarrassing, but also feels totally uncomfortable.

One common solution is to fit a full-fledged bicycle mudguard that can block everything that’s kicked up by your tire.

We know this rider rode in the rain! Look at his back.

Full coverage mudguards aren’t usually the most visually appealing option for your bike though. They rank high on effectiveness as they hug the tire and offer the most amount of coverage for the front and rear tires.

Apart from aesthetic reasons, weight can also be a factor to consider while choosing some form of protection for your bike and your back.

Ass Savers – clever minimalistic bicycle mudguard that’s there when you need it, gone when you don’t.

We have a solution – It’s functional and it’s got a quirky name. Introducing Ass Savers. The clever minimalistic bicycle mudguard that’s there when you need it, gone when you don’t.

Ass Savers is a Company that started off initially as a joke and is now recognized by millions of cyclists all over the world. Being the first mudguards to be used by professional cyclists in the UCI World Tour, it has proven that a good idea can go far.

The humble Ass Saver is a simple yet highly effective product. It is essentially a small mudflap that slots in, underneath your saddle and sticks out just enough to keep your posterior dry. The device simply slides in between your saddle rails from the back and stays there thanks to the patented FLIP TIP Technology.


Ass Savers are essentially mini mudguards. They’re incredibly simple to install, easy to use. It is a universal design fits all saddles.

At first glance, the Ass Saver may not look like it does its job well. It looks small and seems insufficient. However, when the Ass Saver is fit properly – it has “creased lines” that are meant to be folded and bent to a certain extent so that it can be structurally strong and rigid.
A definitive answer provided by experts in Computational Fluid Dynamics!

Due to its small form factor, the Ass Saver is practically unnoticeable and does not hinder the bike’s functionality in any way. It’s almost weightless and super sleek. There are a bunch of sizes, styles, and colors on offer to add your own personal touch. Custom graphics and colors are also a possibility for those who want a personal touch to their bikes.


  • Say bye-bye to wet bums! These ass-savers do just what they claim; prevent your bum (and your back) from getting a trail of dirt on it.
  • Easy to install and remove. The instructions printed on each one of these are clear and you can get them mounted on your bikes within thirty seconds.
  • Do not damage the aesthetics of the bike like how a fender does. (but again, that’s a very personal thing)
  • Sits well under the saddle. Does not flap and neither does it get loose upon hitting a rough patch on the road.
  • Light in weight. Almost negligible in weight actually (for all you weight-conscious roadies out there)


  • It does not protect the back of your thighs or the lower half of your legs. But then, it’s an ass saver, not a fender.
  • As I mentioned above, it does not offer complete coverage to the rider, so if someone is dressed to go to work, then you might want to consider a change pair of clothes once you reach your workplace.



These Ass Savers are perfect for road bikes.
