[RBW] Fixed Flywheel for the Brain

[Davey Two Shoes]

You gotta get some foot retention. Otherwise  you're maybe getting half the 
experience. Its also safer.

[RBW] Fixed Flywheel for the Brain

[Deacon Patrick]

Interesting, Philip. I feel connected with the ground, through the bike. But 
I’m highly sensitive, rather like a canary in a coal mine. Lots of examples, 
but I’ll focus on chairs, for example. Science is discovering they are poor for 
circulation and thus heart health. I suspect they are poor for a lot of other 
reasons. If I sit in a chair, feet on the floor, I have no idea where I am in 
space. If the sitting platform is big enough, I sit cross-legged in the same 
chair, and presuming it’s flat and solid wood with no cushion I instantly relax 
all over because my proprioception can fully engage again. Why can’t it in 
chair postion? I have no idea.

I’ve gotten a few questions about my vertigo and what proprioception does for 
me (all of us, actually, if we let it loose). Quick version: I have damage in 
my brain stem that prevents my brain processing spacial awareness properly, so 
I constantly experience two axes of motion, like I’m in a roller coaster that 
can (and does) go any direction any time, strapped into a “da Vinci” man 
gyroscope twirly chair (like used to train fighter pilots for g-forces and 
disorientation) that twirls about randomly on the roller coaster. 
Proprioception is the ability of the body to know where it is in space without 
(necessarily) the brain having a clue, through tactile input. Lots of “noice” 
inhibits proprioception for most people, especially shoes that have cushion, 
raised heel, support, or does not allow for free motion of the foot.

Chain tension: I haven’t snugged the rear axel and thought the chain was too 
tight, but I also doubt I’ve achieved “binding”. Snug, but not stretched 
(though someone riding a loose chain may disagree. Grin.).

With abandon,
Patrick

I’m not at all surprised that fixed riding is good for your brain, but I’m 
happy it is.

I like a tight (but not binding - I don’t measure it) chain fixed. The 
proprioception through the pedals is interesting, since I’ve never felt fixed 
made me “connected to the bike” so much as “connected to the ground.”

Forgot to say that, I'm glad that riding fixed has been such a positive
experience! Man, I don't suffer your imbalance problems, but I would indeed
have a very hard time replacing fixed gear riding with freewheel riding.

Re: [RBW] Fixed Flywheel for the Brain

That is very interesting! Now, I understand that you have a "perfectly"
tight chain, but still, it's very interesting to hear the therapeutic
effects of no "lag" over TDC, or bdc for that matter.

Me, I don't like a tight chain, and I adjust mine so that there's the
caononical 1/2" of up/down movement; so there's no real flywheel effect;
and *yet* I do feel a smoothness fixed that I don't with a freewheel; and a
sign* that something mechanical is going on is that, when I get back onto a
fw bike after many days and miles of fixed, I tend to pedal jerkily for the
first half mile or so; *and* sign # 2, is that I find an absolutely huge
difference between the fixed S3X hub, with its few degrees of lash, and a
true fixed cog.

Perhaps this, when the chain has the usual accepted slack in it, all has
something to do with the minimum amount of free play between wheel movement
and pedal movement? I haven't figured it out, but I certainly feel it.

* A piece of evidence that is not conclusive but that, because it fits with
the thesis, to that extent supports it; ie, it supports the thesis by the
fact that the thesis would explain it.

In which I puzzle and ponder about why fixed is such a game changer for my 
brain. A few pics of snowy trails too.
