Fendor Bendor Big Detour


The ultimate lightweight gravel mudguard

  • Easy to fit, no tools required 
  • Perfect for Bikepacking or Gravel
  • Super lightweight, only 61 grams
  • Protects your bags from dirt and water
  • Designed by Jesper Jonsson

FENDOR BENDOR Big is ideal for bikepacking and gravel biking. Strong enough to handle really muddy conditions but flexible enough to not break while being bashed around. The width is optimized for tire sizes commonly used by gravel cyclists. Mounted close to the rear tire it will protect your saddle bag as well as the rider from road muck and water. It attaches to virtually any bike in seconds, without the use of tools.

The Detour Kollection is a tribute to those who finds a roadblock as the mark of something great ahead, rather than a dead end.

Most bikepacking gear is not 100% waterproof and a good set of fenders can save you from the misery of having a wet sleeping bag or clothes at the end of the day. Even if your gear is fully waterproof, you will appreciate the lack of mud on your bags when you stop to get a jacket out or when you bring them into the tent after a rough day in the saddle. The full kit adds less than 85 grams to your total weight, making it ideal for ultralight bikepacking.

Visually the Detour Kollection is inspired by the mind-blowing scenery of the Torino-Nice Rally, a 700 km selfsustained gravel event in the French-Italian alps. During the 2018 edition, designer Jesper Jonsson and Ass Savers founder Staffan Widell shared a bivouac on the last night of the event, overlooking a spectacular sunset over the last mountain range before the finish in Nice.

Technical data

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.

Not wind proof

Liked the simplicity of the fit to the frame- on my hardtail mtb- though this was improved with a couple of cable ties to prevent lateral movement.
Comes folded in half lengthways and this fold proved to be a problem I think…
Initially worked well in bland conditions and kept mud off my dropper post great which was the primary reason I wanted it.
Unfortunately in windy conditions though it very easily bent and caught in the wheel and kept folding onto itself despite my working hard to fold into correct position again and again.
Just too flimsy and kept flapping around and buckling on the wheel so had to remove mid-ride.
Also my friends did say it looked sh*t haha.
Wouldn’t buy again.
Am tempted by the skinnier type wings models for road/gravel and I wonder whether they hold up better being shorter and perhaps less prone to buckling under a crosswind… 🤔

Hi Ben,
Thank you for taking the time to review our product!
I'm sorry to hear that you have had problems with your Fendor Bendor. Wind should definitley not be an issue with this product and I suspect an issue with the pre-folding. Please contact our customer support at support@ass-savers.com for assistance or a full refund.

It does what it claims and it does that well

Winter turned to proper winter oretty short after I received them, so I onl used them 2-3 times in rather mudd conditions and they did save what it said it would, so I'm absolutely happy with them. No probs installing them either (A 56 Mason Bokeh frame).

Did not fit my gravel...

Probably good but couldn’t get it to fit properly. The “triangle” space in the frame where the fender should “rest” on was to little on my bike. I noticed to late and in my willingness to get it work out i ”broke”it , So watch out for that.

Quite impressive

This works well with my Kona Rove DL 2021. Fits fine and is surprisingly stable. As other have noted, the frame protection dots could be bigger. Luckily, I had some other patches around. Now just waiting for a Speed Mullet in larger size, for my 47mm wheels. And with Detour paint job, ideally. :)

Excellent ass saving kit :)

I have successfully installed them on my Kona Sutra 2020 and they do the job pretty well.
I had to use scissors though to shape sticky 3M frame protectors and that was the hardest part of mounting.
There was no other problems with shape of fendor as person before me mentioned it.
And they look great and perfectly match with this military green colour of the frame.
I'm very happy with this ass protection :)
