Coker Reliability

Chuck Webb said:

*Just to stay somewhat on topic...i've had my standard Coker for about
4 years now. It doesn't get ridden on any real tough terrain, but it
has worn out two tires with no rim problems. I'd love to have the
airfoil rim, but like others have said, i probably won't upgrade until
i fold the stock one. One thing, though, i wouldn't recommend trying
to use brakes on the stock rim. I tried it for a little while, but my
rim has such a bulge at the weld that it is impossible to
modulate...sent me flying too many times!

I put a slight bend in my stock steel Coker rim one week before I got my
Airfoil wheel back from the wheel builder. That was almost perfect
timing. 🙂

I bent my stock Coker rim on a bad mount. I mounted, was off balance to
the side, and did a slight side hop to recover. It was only a slight
bend and was still rideable afterwards. I took it to a local bike shop
that specialized in unusual bikes and he was able to bend it back true.
The wheel works, but I don't trust it any more. I expect it to bend
again in the same spot.

The stock Coker wheel is weak. The steel rim can't take very much spoke
tension so the spokes have to be loose. The stock hub is very narrow
which doesn't help matters any. The stock wheel works, but given the
opportunity it will bend. It's a wheel failure waiting to happen.

The Airfoil is an immensely better rim. It's stronger. You can tension
the spokes to very high tension and it won't buckle. It's stronger.
Did I mention it's stronger. I'm willing to ride mine down stairs and
go on single track with no fears that the wheel is going to fail.

Put the Airfoil rim on a w-i-d-e hub and difference between it and the
stock wheel is dramatic. With a strong wheel build and a wide hub the
rim does not flex even when pedaling hard up a hill. That means that
the rim will not rub the brake pads when climbing. The wheel is solid.
It gives you confidence to ride it harder. But the cost of such a wheel
is more than the entire stock Coker.

My question which started all this was (facetiously) whether US pounds
were the same weight as UK pounds. *

In the US a pound is something you use to move stubborn things, whereas
in the UK a pound is something you use to pursuede shopkeepers to give
stuff up. It's perhaps a subtle difference.

Oh, weight. Nevermind.

Now I'm really confused! All that Stone stuff had me going, and now
we have to figure out the weight of "heavy water." Normal water is
about 8.34 lbs/US gal, but i guess we'll have to ask Harper about
heavy water.

*

Heavy water is D2O rather than H2O. D, deuterium, is an isotope of
hydrogen, H, that behaves chemically the same but has twice the atomic
mass. This is because it has a neutron and a proton in its nucleus
rather than just a proton. Oxygen, common to both D2O and H2O molecules,
has an atomic mass of 16. The total atomic mass within a D2O molecule is
20 and within an H2O molecule is 18. Heavy water is 20/18, 10/9, or 1.11
times as heavy as water.

Sorry about being off topic. I thought you might really be curious.

Funny, I was just thinking the same thing 😉

*That is my point. 149 lbs should be 10 stone 9, not 10 stone 6. More
proof that the imperial system is confusing even to the English - as
if we need more proof.

Klaas Bil *

149 pounds **is** 10 stone 9.

Yes, the "should be" in my response is shorthand for "should have been
clarified by Sarah as".

clearly a system of 1/14 and 1/16 is not decimal.

Thanks for a new sig line.

Stone (st)
A traditional British unit of weight, rarely used in the U.S. Originally
the stone varied in size, both from place to place and according to the
nature of the item being weighed. A stone of sugar was traditionally 8
pounds, while a stone of wool could be as much as 24 pounds. Eventually
the stone was standardized at 14 pounds avoirdupois or approximately
6.350 29 kilograms -- a convenient size because it makes the stone equal
to exactly 1/2 quarter or 1/8 hundredweight. Today the stone is used
mostly for stating the weight of persons or animals. No -s is added for
the plural.

From 'A Dictionary of Units of Measurement'
(http://www.unc.edu/~rowlett/units/dictS.html), a very nice and through
dictionary. Anybody know the definition of "nice" that I'm using?

Just trying to reduce the confusion a little.😄

Maybe "done with delicacy and skill"? (from rhymezone.com). But why?
