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.
