Coker Riders

Another way to save weight is to get the wheel rebuilt with the airfoil
rim and stainless steal smaller gauge spokes. That along with the
previously mentioned lighter tube set up will greatly reduce weight.
Reducing weight in the wheel is also much more easy to notice when
riding. Frame weight really isn't going to slow you down as much as
wheel weight, it will also make the wheel stronger and it will make it
easier to control.

I have a Hunter 36" that is phenominal. I spend a chunk of change on it
but it was well worth the investment. I don't know how much lighter
than the others it is but as DustinSchaap stated, your not going to
save much weight on the frame. The two best places to look to lose
some weight is the wheel/tire/tube and the rider. Often overlooked but
the one area where you can lose the most weight is from the riders
body. While you can only shed ounces off your uni, most people can
shed pounds off their bods.

As for cycle computers, I've switched to a GPS device to avoid wires,
wheel sensors and flying computer heads when I UPD. I use a Garmin
Forerunner 201 that I wear on my wrist. It's a bit bigger than the
newer "spiffier" models but it was a lot cheaper and it works just
fine.

What Dustin said 😎

Best to save weight on the wheel first- SS spokes, Airfoil rim, Coker
(not TA tyre), Tubeless or 29'er inner tube. I've heard lot's of
people having problems with 29'er inner tubes, so personally I think
tubeless is better. Tubeless rides nicer too- you get a springier feel
to your wheel.

I still use a Std Coker frame- most of the custom frames are overly
built- possibly to eliminate flex. But I don't notice much flex in my
Std Coker frame, but then I don't use a brake either. To get a really
light frame you need to get one custom made- maybe with thin, double
butted good quality steel, aluminium, or carbon-fibre (glue them on to
the crown) bike tubing.

Don't forget the cranks and pedals- these can be quite heavy. Get some
alloy cranks. I hate plastic pedals, but if you really want to
sacrifice performance for weight, then these are probably lighter than
most of the BMX/Trials pedals out there.

I am upgrading my Diet Coker this weekend- will post pics and a weight
once I have it up and running.

The specs will be:
Coker Tyre- Stans tubeless conversion
Airfoil Rim
Tommy Miller SS spokes
UDC hub
Schlumpf alloy 114mm cranks
Wellgo MG-1 Magnesium pedals 390g (the lightest, broadest, flattest,
grippy platforms I could find)
Schlumpf 36" rejected Generation-1 frame
Cut down steel seatpost (will upgrade to aluminium later)
Miyata carbon fibre seat, dual density foam, leather cover
Wallis Deathgrips (I actually prefer GB4 handles for distance, but will
put these on for the exercise of building up the Diet Coker).

I can't think of anything else to make it lighter right now.

I just started riding unicycles, I'd like to learn to ride a big wheel
after I figure out how to not fall off this tiny thing I'm trying to
cruise around on.

I'm in Royal Oak, so not to far from you.

Sorry I missed you and Tony in Bangkok.

Coker weight is all in the tire and the tube. Frankly, I view this as
an advantage because the rotational intertia adds stability. It also,
however, makes turning cumbersome. I'm not looking for a nimble Coker,
I'm looking for a cruiser. That's just me. I don't own a cyclometer, a
custom frame, or GPS. I don't have spider-web, tapered spokes or a tilt
rail adapter. I don't even own a cell phone. I probably never will. I
like to ride in scenic areas with friendly people on a zone-out,
comfortable machine that runs on autopilot. And I like to stop a lot.

I have only owned a Coker for less than two months with 600+ miles on
it. But I must agree with Harper. I also enjoy a nice long ride too.
Also, the first pound of weight can be removed fairly easily. To
remove the second or more pounds the trouble and/or expense increase
substantially.

For computer, I have had great success with the Cateye Enduro 8. Good

tickin'.

Welcome David Goldman!

I love my Coker, and used to ride it 8 miles each way to work. Now I
don't work there anymore, and it's hard (for me) to get the discipline
to ride lots of road miles without a destination. I haven't been on
mine for a while.

But the last unicycling I did was on a 2-speed Coker (Schlumpf hub) in
the Marathon race at Unicon. That was a blast!

Yes, like a bike, the main weight to try to reduce is whatever rotates.
But if your goal is a good workout, leave it heavy. Your part of
Michigan is flat enough...

Most any cycle computer will work. I've got one sitting in a box and
one day I'll need to hook it up. At that time I'll have to dig up the
right number; the one that represent the wheel's circumference. Anyone
got that handy? Oh, it's probably linked just above this post...

Anyway, Goldman has been around unicycling for a while. As he said, he
got his first big wheel the same year I got mime. He rode in (or at
least he was there for) the *first* Unicon Marathon, a measley 8
kilometers at Unicon IV. This most recent one was the real deal, 43k!

You can easily drop half the weight and it will still feel stable and
comfortable over long distances.

No I don't.

I could do the exercise again if I have good data from at least six
people, preferably ten or more. What about the different rims now
available, do they all have the same width as the original Coker one?
Because that would matter too, to a slight degree. Then I need even
more data, obviously.

In a study of this precision, it is important to maintain as many
elements of consistency with the original body of evidence as possible.
Skew can be introduced in so many seemingly insignificant ways...the
quad size of a new rider, the thickness of the padding in their shorts,
pinned pedals versus those cheap plastic ones on the stock coker. It
is critical to minimize variation!

As an original participant, I will agree to maintain an ongoing role in
this important research. PDC, I believe you have my address from our
previous transaction. Please mail me one of those new TA tires as soon
as possible. I will promptly enlist john_childs to install it so I can
begin gathering data for Klass immediately.

If you act promptly, there's no reason we can't have this whole thing
pinned down by Christmas.
