Oh boy, I had trouble fitting this to my bike. It took me like 20minutes (it`s still faster than mounting fenders, but I expected a faster procedure). The problem was long bolts, that hold my saddle to a seatpost, the prefolded front end of ass-saver kept hitting the bolts when I tried to thread the ass-saver between the rails. Anyway, ass-saver mounted and holds there rock solid. After all, I`m glad that its like that, because I was afraid it will fall off during aggressive MTB ride through roots or other gnarly stuff.

Hi, bought an AS Original at my local Evans. They said I would have no trouble fitting it to a saddle with a little bag attached to the rails. They were wrong! I had to detach the bag brackets, fit the AS and reattach. I certainly can't easily fit and remove the AS and I'm wondering how effective it will be. I can't be the first person to have this problem? Was I sold a pup?

Hi Andrew,
The fitting of an Ass Saver and a saddle bag is in most cases no problem. However, due to the thousands of combinations of saddle and saddle bags and their various attachment systems, it's not possible to say that it will always fit. This is why don't make this claim officially in spite of many happy users with a working combo. If you feel that your local Evans gave you misleading information, you should talk to them and ask for a refund of your purchase.

Worked great on my first commute, but on my way back from work(Less than 5 mile ride) it fell off, leaving my bum wet. Kind of disappointed, and more when you pay the extra $10 for the RHC edition...

a refund would be cool. or another would be best.

Hi Juan,
I'm sorry to hear that you lost your Ass Saver. The most common issue when they are lost is either that pre-folding was not done properly or that your saddle/seat post combination prevents the Ass Saver from engaging correctly. Either way we will replace your lost Ass Saver and try to find out why this happened. Please send an email to

I've got the original on my CX bike and the wide on MTN bike and both do a great job of keeping the crap off my butt. My chamois doesn't feel like a loaded diaper after 10kms and I can confidently walk into the local coffee shop without worry that they'll need to hose off their chair when I leave. A clip on plastic fender will do a better job of keeping you dry most times but for off road rides these stay in place much better and they don't bang around while running obstacles with your bike on your shoulder. I'm in the process of bulk ordering a custom designed Ass Saver for my club.

I've had a bad experience such "keep your butt dry on wet roads". Is this a newer model where it has been enhanced ? or I may have an older model where water would by pass the fender .

Hi Victor,
The Ass Saver Original is our third generation of saddle mudguards and although it is not longer than the first generations, improvements have been made to ensure a proper fit on the saddle which is important for full butt protection. For those wanting a little bit of extra cover we've developed the Ass Saver Extended and the Ass Savers Wide. Please send us an email with a picture of your setup and we will try to do our best to save your ass!

Totally wicked. Fits on all my bikes, got one for my CruX, one for my Venge. Noticed the Lotto-Jumbo team riding them in races, decided to give 'em a go. Works great on rainy road rides AND EVEN cyclocross races. So simple, so effective. The Swedes know what's up.

Great product, takes 10 seconds to install and works amazing! not only that, but it looks cool!! shipment was fast and product is of very good quality.

I've had my Ass-savers for over a year now. It pretty much lives on the bike as a pernament mudguard as it's so light it's just not worth taking it off or folding it away.
Yesterday I day a major blowout in the middle of the bush and the rims tore two large holes in the wall of my tyre. I snapped the Ass-savers in half and used it to block the holes. This saved my ass big style! Online now to order more but if I hadn't have needed it to get me home, it would have sat on my bike for many more years. Thanks Ass-savers, you did!

Have used to great effect in past. Bought new ISM road saddle to protect my fleshy but not just from the rain and new ass saver- very disappointed that it does not fit due to shape of rails and another couple of atypical features. Do you have any plans to bring out a product compatible with this saddle. Love the company and product else wise.

Hi Tim, Thank you for the review! We are constantly trying to improve the products and next generation will for sure expand the range of saddles that we can accommodate but there will always be the odd bird here and there that is a bad match. At this stage we have no plans for a ISM specific Ass Saver.

Very disappointed... After purchasing the Ass Saver and properly attaching it so I could ride in the rain, it fell off during my VERY FIRT 25 mile ride. I got home from my ride and the Ass Saver was gone. Needless to say my Ass was NOT saved :(
Waste of money.

Hoping that the Ass Saver team might provide good customer service and offer a replacement...

Hi Henry,
Sorry to hear about your issue with the lost Ass Saver. There are some combinations of saddles and saddle posts that are a challenge to the Ass Saver but mostly it's a mounting issue. Please send an email to and we will try to figure out what the problem is and find a solution for you. If it's something that we can solve, you are of course entitled to a full refund of your purchase.
