On-bike mud scrapers?

[cantunamunch]

Does anyone know of a workable solution? Perhaps using the fender/mudguard eyelets?

After having about 3" of packed clay and .75" gravel stones wedge itself into the back side of my fork bridge after riding across runoff silt on "paved" trails, this is something that is rather called for.

My fork took a beating after that race. Or rigid fenders that act as scrapers. I saw quite a few mangled fenders in the mud.. best laid plans and all that..

 

[cantunamunch]

Yeh, it pretty much has to be a cheesewire type system, or rock/clay mix will just hammer wedge its way up there.

I believe you are fully capable of making something like this yourself:

If not, like this:

I am. Also fully capable of knowing how useless that is.

Yeh, too thick. Go look at the sort of wires potters use to cut items off the wheel. And then we need some sort of struts to hold the cutter below 9 o'clock position.

Nowhere nearly as trivial as you think We're talking about stuff that wrecks forks and destroys metal mudguards.

If not, like this:

I can see you've never ridden in muddy sticky gravel. ^That would have been destroyed in about 30 seconds.

I already have something like that on the bike that is much more durable - the chainstay bridge and the fork bridge.

Now imagine about two fists' worth of concreted aggregate, clay with embedded rocks, punching into both the chainstay bridge and the fork bridge, wedging itself into that space.

Enough to stop the wheel rolling completely from like 15mph. Enough to rip V-brakes off.

I think the fork is still OK. But it was a near thing.

If your solution can't cut through what is essentially wet concrete, it's not a solution.

Excuses,excuses. I am giving you the general strategy. Local tactics is up to you, general.

I think the strategy I am going with next time on my bike is narrower tires - at least some of the rocks will have a chance to get flung off.

No idea what I will do on my nephew's bike.

This is after the second wash - 6 liters of pressurised water later - there was still ~300g of rock trapped in the brakes and bridge:

Sometimes you gotta just shoulder the bike and run.

 

[scott43]

This is after that one mud ride. Oclv fork...

I was saying, I couldn't physically shoulder my bike. It must have had 30lbs of mud on it.

 

[cantunamunch]

and you were all laughing at my choice of brown shoes, aha

 

[cantunamunch]

Well at least I didn't have clutch and chainkeeper to worry about

 

[scott43]

I feel his pain..

And I beat that LOSER who QUIT after 2 hours!!!

 

[wooglin]

Y'know, we used to have a solution for a similar problem. Actually came on some new bikes. Would need some re-jiggering to stand up to the rigors of mud though.

I still wipe my tires with my hands to this day. #tubulars

You know the new gloves are sometimes pretty thin. Have to be careful...

"unique style of mud" - yeah maybe unique to California riders. Cement silt with rock chunks is nothing remotely new over this side of the map.

 

[cantunamunch]

^ he makes the assertion that oversized pulleys helped his DR survive as long as it did. Thoughts?

 

[scott43]

Yeah bigger pulleys less stress. I can see that but hard to quantify.
