shaft drive math

The shaft drive idea sprung on us full volume with summer ahead filled
with chain woes.
I don't mind it mutch-80 hours purr year? Always down wind ahhh!!
Right?

So eyooow! $299 shafted!! nickledime!!Or $1700 custom from Chinese
Ferrari dragon- or a Bria!!!

Now for the equation! The $299 sez honestly that several gear surface
friction areas as driven do not match the total friction area in a cog
chain setup as driven coming in at 10-15% less efficiency than the
chain setup.

Except a few grains sand and a few grains reduce the chain's clean
efficiency rapidly-in the side plates?

To what??? Math people spring forward with a ratio and a grit factor
(E.D.)

My guess from sand country is I spend 70% of my riding time with a once
a week/100 mile commuter cleanup at the efficiency level or below
clamed by the $299 shaft grafted to Walmart's behind range.

Well, back to the garage. The magnetron is charging magnetron
fluid(still somewhat corrosive) in the cassette belt drive's nylon
gear housed reservoir.
we have replacement metal gear surfaces!!
and We're getting +15% gravitational float over the four cogs two
rear-two front!!
And the cog clutch deray mechanism works under full load!

no more chain suck though, huh?

I think he might be saying he has come up with a gear mod on a $299
dollar Chinese shaft drive system that is more reliable in sandy
conditions that chain drive or the unmodified drive and is competitive
with a high end belt drive system.

time for another link.
the cassette/synthetics/belt from CR to gear Cluster fully enclosed
receives warm support!!

the shaft drive(s)need a five model Consumer Reports review
and volvo steel plus timken bearings
less i and you shout Fiat Fiat Rover
and you guys need to go to the zoo for a brain transplant.

Slow down. Take a deep breath. Count ot five. Now start again.
This time try to use complete sentences, punctuation, and some form of
linear progression from one thought to the next.

Right?

With summer coming, my mind turns to the idea of a shaft drive bicycle.
I don't mind chain maintenance - I spend about 80 hours a year
performing it.
It's a pleasure to do so, isn't it?

So eyooow! $299 shafted!! nickledime!!Or $1700 custom from Chinese

But yowzah! I've found a shaft drive bike fo $299 online! [Probably an
Incline 3-speed.]
That's not too much money! Or I could spend $1700 for a chinese-made
one that's sportier. [Probably a Biomega.]

Now for the equation! The $299 sez honestly that several gear surface
friction areas as driven do not match the total friction area in a
cog
chain setup as driven coming in at 10-15% less efficiency than the
chain setup.

Now for some calculations. The low-cost alternative mentions that the
efficiency of a shaft-drive bike is about 10-15% less than that of a
conventional chain.

Except a few grains sand and a few grains reduce the chain's clean
efficiency rapidly-in the side plates?

However, sand can get into a chain's side plates and reduce its
efficiency.

To what??? Math people spring forward with a ratio and a grit factor
(E.D.)

But to what degree? Could someone more mathematically inclined than I
supply a 'grit factor' that could be used to calculate real-world chain
drive efficiency?

My guess from sand country is I spend 70% of my riding time with a
once
a week/100 mile commuter cleanup at the efficiency level or below
clamed by the $299 shaft grafted to Walmart's behind range.

My feeling, based on living in a sandy place, is that my chain is less
efficient than a shaft-drive system approximately 70% of the time, as I
clean it weekly or once ever 100 miles.

Well, back to the garage. The magnetron is charging magnetron
fluid(still somewhat corrosive) in the cassette belt drive's nylon
gear housed reservoir.
we have replacement metal gear surfaces!!
and We're getting +15% gravitational float over the four cogs two
rear-two front!!

Time to do some tests. I've spilled coffee on my transmission [?],
and I notice that about 15% of my chain is floating away. My bike is a
four speed.

And the cog clutch deray mechanism works under full load!

At least I can shift under load.

Oh, ****.

Personally, I think his time would be better spent shielding that
magnetron before it does some permenant damage.
