Almost Unnoticeable!

If you look really closely you might just be able to see my first experiment in mud deflection.

Very subtle.

3 years of a product design degree put to good use ;)


09:05 03 Sep

You actually bothered to use cable ties! Run out of Duct-tape? ;-)


09:05 03 Sep

Isn't all the shite just going to get dragged in off the disc anyway?

much better would be a converted crud-claw (crud-prong) that sits at the back of the calper low and close the dosc, bolted by an articulated arm to the lower disc mount that scrapes all the crap off as the disc spins so it doesnt get forced into the brake...

runs to patent office...


09:17 03 Sep

That won't work Tim.
1: it would drag like crazy as it would need to be tight to get enough dirt off.
2: it would push the dirt into the holes in the rotor, which would probbaly come out and hit the pads as it passed.
3: I'd already had that idea before. and discarded it as being annoying listening to it's brushes (i ws going to use two toothbrush heads) but they would wear out quick and be noisy.

The point is, Tim, that that the dirt comes in from the side from my shoes, so there should be little mud comming onto the rotor, as mud from the rear tyre cannot make it onto the rotor, so it's coming from infront of the wheel, the frame protects the rotor for frontal splatter, so this should reduce sideways splatter.

zip ties because then I can remove it and move it, and it's more secure than duct tape.

a small, powerful jetwash, that sits on the seatstay and blasts the disc clean as it spins :-)


09:33 03 Sep

The initial shimano dh disc brakes had a water resevoir that sat under the saddle with a hose that led to the disc - dripped water on it to cool the disc/caliper,maybe you could improvise something from that :-)

(they also had two discs on one side of the wheel and a triple decker caliper apparently)


09:49 03 Sep

It's beautiful.

IIRC some moto-x bikes have a similar thing on their discs.


10:12 03 Sep

As a wise man once said, "Insania"


10:36 03 Sep

Maybe you could adapt the old school bmx brake gauard - check this page out right at the bottom!!


10:53 03 Sep

You could make money by selling advertising space on it. Most billboard posters I've seen would fit on there.


11:44 03 Sep

Just bodge a couple of these:



12:21 03 Sep

Wow, I lot of responses.

Yes, Motorcycles have had them for years, and if anyone payed attention in the 90's THE did a front one for mountain bikes.

Other replies include: it's that shape so I can cut or add bits to it, then I will refine it. or just use servo waves.

If you had my brake pad problems you'd probably do something similar.


13:04 03 Sep

If I had your brake pad problems, I'd ride fixed :)


13:05 03 Sep

I'd imagine you'd still need two brakes on a fixie.


13:31 03 Sep

Why don't you just get a custom frame with an IS mount on the chainstay and on the dropouts and run two discs with a Hope hose splitter? You'd have lots of braking power and there'd be so much ruddy metal there nothing would ever see the rotor :)

I like Weon's idea. You could do a mk.2 version with a Picadilly Circus-style illuminated display.


14:41 03 Sep

you could covert to post mount and with a sheet of plastic create a tupe that covers the caliper all the way round, it's so simple its bound to work! ps I have drawn up plans whilst working if required ;-)


14:45 03 Sep

Serious Answer:
putting the caliper in the frame angle would put it right in the way of the mud coming off my foot.

Two discs would just mean I go though 2 sets of pads per ride not one!

Don't forget that I ruled out the act of braking as the reason for pad wear.

You all also seem to be forgetting that this is an /experiment/, if it works, then i'll make something prettier, if it doesn't I'll think of something else.

If I had access to a vacuum former I would probably have done something nice with that, but again I refer to the *EXPERIMENTAL* nature of this project.

"you could covert to post mount and with a sheet of plastic create a tupe that covers the caliper all the way round, it's so simple its bound to work! ps I have drawn up plans whilst working if required ;-)"

Bloody hell, keep up..
covering the caliper is probably not going to make any difference, as the mud's being dragged though the brake as the rotor waterwheels the dirt though.

Your tube idea is no different than my placement of gaffer tape which I did last winter, which, whilst worked a little, didn't create earth shattering results.

So: to sum up, protecting the rotor for splash FROM LE LEFT FOOT, is what I am trying to do.. oh and wait.. I HAVE. It;s not pretty, but it's *EXPERIMENTAL* and frankly I don't care if it looks ugly, I don't look at the back of my bike when riding, and other people will see it for the second I'm cruising past them on the trails so clearly they're riding too slow and they opinions don't matter to me.

To Sum up the Sum up.
I don't give a crap if it works and saves me over 300quid a year and means I can ride for longer when it's raining.

cut your leg off


16:29 03 Sep

a solid disc and two bits of sponge held aganist the disc by a gently sprung clip

c'mon youd enjoy the exta effort anyway!

or go samuri, remove your rear brake, and tow a boat anchor - that will slow you down ok :-)


16:33 03 Sep

"a solid disc and two bits of sponge held aganist the disc by a gently sprung clip"

Your ideas are getting worse.


17:16 03 Sep

a buxom wench who can hang of the back of the bike and use her enormous soaped cleavage to brush either side of the disc to clean it off...


12:17 05 Sep

This is the best post ever on the site :)


14:33 05 Sep

Since I made my *EXPERIMENTAL* device, it's not rained.. I will make more of them and it will never rain again. wooha!
