The Ass Savers 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.

For the rough stuff

It has been developed for gravel and adventure biking but is also a great protector for CX and Mountain Bikes. 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

This model comes 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.



  • Easy to mount, no tools required
  • Perfect for Gravel or MTB
  • Super lightweight, only 61 grams
  • Longlasting, durable materials
  • Suitable for tire widths between 32-55 mm


NeilAnother great product from Ass Savers unfortunately better suited to an mtb as just a little too big and bulky for my gravel bike.
Mr NatarajReally well made product. Some issues fitting it to my Trek Checkpoint SL. The location of the bracing bridge on the seat stays means the guard will not pass through. I contacted Ass Saver directly who were really helpful and suggested mounting directly to the seat tube unsupported...this makes it very similar to many other products though. It does work well is light and easy to remove, but check exactly how it will fit on your bike !
Ben JewellLight and easy to carry. Quick to set up and attach and is great for keeping the spray off your back in really wet conditions. Definitely worth having as an addition to the smaller Ass Saver.
martinI had to adapt it to get it to fit my bike, but it's very good at keeping the muck of your back
Mr J SSolved my problem brilliantly. Not used as designed but attached to the back of the down tube with tiny cable ties to prevent tyre spray not contained by the race blade pro in the back. Great quality plastic, lightweight, easy to assemble. Well happy.
Sam4aBought for my new hybrid and very pleased so far. Low cost & light. Needed to be trimmed to fit, but very easy to do so. Keeps your bum dry and mud free.
Mr MckenneyItem was a bit of a fiddle to fit, not quite as simple as the makers video suggested. Once on the bike it performed admirably. The product was competitively priced and the service from Merlin Cycles was 1st class, will use them again.
HughReplaced my Ass Saver Regular mudguard as I'd changed the saddle bag which prevented it attaching to the saddle again. Fendor Bendor fits my Tripster AT easily and works a treat, good padding but I used helicopter tape for additional protection for the frame. Doesn't fit my MTB due to FD cabling going down the seat tube.
