The FENDOR BENDOR Big gets the dirty job done. The all new attachment makes fitting without tools a breeze, to virtually every bike in just a few seconds. 

Universal fit
With the newly developed attachment construction, 
FENDOR BENDOR Big is now completely self supported and therefore possible to mount on bikes without the sideway support of the seat stays or the support of a brake bridge. You could also mount it above your caliper brake to avoid interference with the brake.

"...once I expect to do more wet gravel riding in the winter, it will get strapped back on the bike and left there until spring comes." Cory Benson, Bikerumor 

For the rough stuff
It has been developed for gravel biking but is also a great protector for CX and MTB. With greater length and width, it's well suited for the longer wheelbase normally associated with this segment of bikes. A single midway fold still allows for convenient minimal storage but with maximum sturdiness for the rocky roads ahead.

Frame protection by 3M
Both models come with upgraded frame protection stickers from 3M. A material originally developed to protect the helicopter propeller blades from the sand storms in the desert, it makes sure that no scratches will be made to your beloved bike by the FENDOR BENDOR.

For front protection, consider adding a MUDDER Mini or SPEED MULLET Regular

Weight: 61 g
Material: 1 mm PP (Polypropylene)

The Fendor Bendor fits all frames with standard seat stays. It's self supportive and doesn't require support from the brake bridge or the seat stays. It can also be mounted directly on a seat post (as low as possible for best effect). The Fendor Bendor will not fit if you have monostay frame or center pull brake.

The scoring lines along the fender need to be folded hard in order to give the it the necessary rigidity and strength. Take extra care to fold down the outer edges to make sure your Fendor Bendor is functioning properly.

Frame protection
Each Fendor Bendor is delivered with a small set of transparent 3M polyurethane protection stickers. Use these to protect your seat stays from scratches from the fender.

The Fendor Bendor Big can be folded in half for easy storage in a backpack or strapped on your bikepacking gear.

Really the ass saver!

It's really work!! Riding in wet weather with it does make a lot different.

Careful with frame shape

As it is supposed to go through the frame, better check if it fits the shape of your bike. I have a specialized sirrus x2.0, and it's not compatible. Still works as a temporary option.

Couldn't be better

I've been struggling for months to find a decent rear mudguard for my carbon Cannondale Topstone. The rear suspension (and therefore the moving rear triangle) makes it really hard to find one that works, especially with my 37mm tyres. The Fendor Bendor is absolutely perfect though and it doesn't sway at all even though my bike has no seat stays. Couldn't be better.

Hi Voks,
We're sorry to hear that you've had a bad experience with our Fendor Bendor. The issue that you describe is normally associated with lack of correct pre-folding, which you also found difficult for your bike. If you would like to contact customer service at support@ass-savers.com, they can tell you exactly what the problem is and hopefully help you to a better fit and product experience. If it still doesn't work to your satisfaction, we have a 100% happy customer guarantee and you will get a hassle free refund of your purchase with us.
Hope to hear from you soon!

Overall its a good rear mudguard but doesn't fit Specialized Diverge Base E5

Bought this rear mudguard hopefully it will fit my Specialized Diverge Base E5 but it doesn't fit.

Have to sell it off and look for other kind, overall it's a good mudguard after receiving it.
