Video: Why Does Joe Barnes Fill His Water Bottle with Moto Foam?

Aug 14, 2020
by Joe Barnes  

Time to delve deeper into a few Juice bottle modifications. The securing system is genius but the anti slosh set up needs some discussion.

Have a watch and let me know what you think?

Bike stability, sprung and unsprung mass, is it negligible, does the juice still taste nice, where do you want the weight, etc. Plenty to be going at.

 too much of an increase in surface area for bacteria growth on the foam, plus you could never get it fully clean. Good in theory though.

 I think tri water bottles have a thing like this; triathletes may do some weird things but seem to survive ok.

 My thought too. Plus in SoCal, one needs that 50ml. I do appreciate the ingenuity though.

 Moto foam is cheap, just replace it after a certain amount of time.

 Only filthy casuals reuse foam.

 Keep dry bottle in the freezer when not in use. No bacteria growth. No mold or mildew. Same goes for bladders. Your welcome.

 That's assuming that you clean your bottle and don't just refill it as soon as you're headed out again. Ha some of the water in my bottle has to be from several months ago at this point and I'm positive has special healing properties and enzymes to cure the Corona virus.

 I throw foam in my drum sterilizer with my surgical instruments. Works well and when I run spore tests it always has sterile results. So single use sterile, not just disinfected or ‘clean’ uses are possible.

 I'm not top 5% biker, but I don't think I've ever thought 'Damn, the water sloshing side to side is really throwing my balance'

 Neither have most top tier racers lol

It’s a neat thought though. Seems a little gross but who knows.

 I'm kind of with you, but I've always noticed the bike handles a touch better without a bottle on, and after a bikepacking trip last weekend I'd wondered how much might be water slosh rather than weight after feeling the effect of a bit of a wobbly tailpack. The bottle is fairly low and central anyway on most frames. If I can suss the hygiene I genuinely might try this.

 Think of all the ways we could apply anti-slosh technology! We could also stuff moto foam in your suspension to stop the fluid from sloshing. What about stuffing moto foam in your bladder or even in your stomach? The possibilities are endless!

 more concerned about water bottle then he is about a dated suspension platform from 1997. there is bigger gains to chase man. (Yes I am a huge Orange fan but there are no doubt some pretty notable improvements in suspension that just can't be ignored)
  • 15 7
 That's like saying dirt bikes have not evolved, since they use the same basic layout since 1982. There are many current release single pivot bikes out there, that you might not even know are single pivot. Most MTB improvements recently have been with dampers and geometry.

 Why do you care. He clearly enjoys riding his bike. Why should anyone care about someone else's suspension linkage if they are clearly having fun riding their bike?
  • 4 1
 But he was on Canyon before starting Hazzard and getting back with Orange. There's an interview somewhere where he talks about the bike suiting his style of riding, in his words as best I remember them "riding through the feet alot, with pleny of back wheel steering."

 So...dairy tankers & fuel truck have a port/baffle system inside made of metal so that the fluid has to push through it like storm grates on a sewer. Slows down the ballast as the trucks shift or stop & go.
@Hazzard-Racing just as an FYI, if you can pick up a pack of BPA free drinking straws, you'd actually be on to something. Pack them all into the bottle, fill as needed, and the fluid would still squeeze out unabated & you would have no toxicity.

 I believe they used to do this with fuel tanks on GP bikes back in the Schwantz/Doohan days to stop the fuel sloshing around when the tank was full at the start of races.

 @jaame: it was definitely a noticeable issue on older motocross bikes. In the mid 80s, I rarely filled my tank so my KX125 wouldn't swap

 I think he’s got it backwards. I think the sloshing water in the bottle will function as a dynamic vibration absorber, actually making your front triangle oscillate less. Silly man...

 I think its ingenious. Sure, might be a bit dangerous, and I'm certain there are some chemicals there you'd best avoid, but that is a pretty cool idea! I wanna try it!

What the heck is moto foam though?

 fish tank filter foam or any coarse foam really, can also use the foam that's used in rain gutters to keep leaves out

 Wow. Weird little tinkering bits like this make me happy.

 I use to have a KTM Motard that held 3.1 gallons of fuel basically in the rear fender and as the fuel level came done and it sloshed the negative effect on handling was very noticeable. Quick side to side motions, hard braking, etc all suffered. In that case when I added Motofoam it made a pretty significant improvement in handling. As far as my bike, not sure I spend enough time at mid levels of water in a bottle for it to matter at all.
  • 1 0
 I wish I cornered hard enough for my gas slosh to matter. One time I did stall because my bowl sloshed so hard I pulled dry on a hard rut turn though, and I am infinitely proud of that.

 micro plastics are good for the microbiome
  • 4 0
 Nah. The sloshing is good. It's a G-force damper. It will only hit hard at the end of the movement, when the bike is already settled. The freeer the water, the more weightless it can be until that point.
  • 5 0
 this is the real science!
  • 2 0
 Except its not the bike piloting itself down the hill and so keeping things consistent feeling is going to help. Stopping water sloshing about makes the bike feel the same in the turn as it does on the straight, the jump and elsewhere. As the bottle empties it doesn't change properties with this method.

 There's a fine line between brilliance and madness. I think he's right on the cusp. It'll be interesting to see which side he falls on.

 If the bottle affects the taste of the water the chemicals are leaching out , not a good thing. That moto foam has got to be leaching out chemicals.
  • 6 0
 Nit sure about chemicals, probably really bad. but the water tastes totally fresh with the foam. no leaching of flavour.

 I honestly had to read the comments to understand WHY you’d even want to do this.. how does 500ml of water throw you balance? I mean maybe I’m no “skilled” enough to notice it but just seems like a pretty minuscule thing that’s probably no gonna make a difference...
  • 5 0
 Its for suspension benefits and making the most of potential main frame weight. not so much balance as the slosh wouldn't put you off this way. Just did is cause in theory its better, however miniscule.
  • 2 1
 Test it. Ride a rock garden with 500mls of water, then the same section with out the water. I’m a lightweight and I notice the 500 grams extra. Softens the bike up for me
