My upcoming Clem will pull occasional MTB duty. Our trails tend to have lots of sticks and vegetation, so I'll probably remove the fenders.

Has anyone rigged up a way to attach fender brackets in some sort of quick-release fashion? Perhaps hardware like this has potential, if the right sizes are available...

(I'm aware of Speed-Ez and other truly QR fenders, but they lack both width and overall coverage.)

Perhaps SKS qr (safety) stays and Sheldon nuts f and r? If there are other ways that accommodate threaded bosses at bridges and under fork crown, I'd like to know myself.

If anyone does, I'd be interested in knowing too.

Your idea of using the SKS qr's front and rear sounds good. You really wouldn't need Sheldon Nuts on a bike with v-brakes, it's just a matter of pulling two nuts-and-bolts at the bridges and and pulling the stays out of the qr's. It's not quite as fast as just walking up and yanking fenders off a bike, but probably fast enough to do before a weekend, then put 'em back on a few days later.

Tully, I struggled with this for years and finally gave up fenders because I benifit more from having nobbies than I do from staying dry from the road/trail. Put another way, I want to ride my bikes on whatever I ride and that is on average 1/3 each paved, dirt road/mup, singletrack trail and around here that means nobbies. Here are the conclusions I came to for myself:

— slicks (like Compass non-nobbies) as well as small nobbies like Thunder Burt work great with fenders no matter the terrain, but singletrack may require they have greater clearence.
— Singletrack is hard on fenders and their bits. They will make noise and need frequent adjustment, making them, for me, fiddly.
— If going without fenders, drivetrain will suffer some, but not as much as I thought it might; gaters are brilliant to wear, and a small MTB SKS front mud guard blocks slop from hitting my eyes at speed. Usually. Grin.

With abandon,
Patrick

A number of years ago Bontrager (Trek) had a truly full coverage, quick release fender. They only had it for about 3 years and discontinued it. I worked for a Trek dealer at the time and it looked like a good product. It seemed to work well. Don't know if the test of time determined they didn't and that is why it was discontinued.

Here's what I have on my Hunq:

I bought a piece of metal at local hardware store and filed off some bit.
I attached it to the fender / kickstand mount on chainstays.


I inserted a T-nut to fender, and a wing bolt to the T-nut. (Some creativity will be required if your fenders are not wood.)


I bought an L-shaped piece of metal, filed off some bit, and attached it to the sliding clip (bridge hardware) of the fender.


I inserted a long (50mm?) bolt into the hole of seatstay bridge (inserted upward from under the bridge), and put some nuts, washers, and a wingnut.


...And I can remove it without a tool!

(Sorry about lousy movie)

Forgot to add that I put SKS QR on rear dropout.

Takashi,
That is awesome!  Did you create something similar on the front.
The video and photos are quite helpful.
With thanks,
Erl

Takashi - brilliant! I'll have to take a stab at something like that. Spaced out and forgot that I will have v-brakes which greatly simplify things (as Joe pointed out)...but I'm all for clever solutions anyhow! 

Reginald - sounds like a cool product. Time to peruse eBay...

Relevant: https://www.sks-germany.com/en/products/speedrocker/

Coming in January, and supposedly good for tires up to 42mm. Not the fullest coverage (or my aesthetic preference), but not bad!

Sheldon fender nuts and front fender goes on/off in less than two minutes.

Same for rear fender, EXCEPT for the chainstay bridge bolt attachment. Maybe zip tire the fender at that point and just take 20 seconds to cut ties when you want to remove?

Thank you Erl.

Front fender is attached with ordinary bolts.
I did this to the rear fender for rinko-ability. (Bringing my bike into train)
I need to remove rear fender, but not front fender.
When I pack my bike, I remove whole front fork from the frame. Front fender and rack stays on the fork.
Technically you can bring your bike into train by simply removing both wheels from your bike, but I have front fender and front rack, so removing whole fork is easier for me.

Tully,

Several years ago I saw a photo in a bike magazine which showed a quick-release rear fender.
I think I threw the magazine away, but I remember that it had a latch catch clip where it attaches to chainstay bridge.

When you create your quick release fenders, please post pictures!

These PDW fenders are apparently quick-release, although I've had an oddly difficult time finding anything that shows how it's done.

Joe-

Watch the video on that page, and it's clear that the rear fender uses clips at the seat tube and brake bridge.  So the rear fender could be removed with relative ease.

The front fender, however, attaches to the bracket before you bolt it to the fork crown, so it would require removal of that bolt to be removed (Sheldon's nut would make that relatively easy.

However, these PDW Sodapop fenders don't provide that much coverage, and since they have no stays they would likely vibrate all over the place and create a noisy racket.

That's the odd part, I don't see any video or instructions of how the front fender detaches from the bracket. You'd think people would want to know how a quick-release fender quick-releases 🤔

I have the front fender on my commuter set up for quick removal.  I threaded machine screws through the drop out bosses (pan head) and fork crown and use thumb nuts to fasten the fender.
