Yip it sure is. I saved over 1kg from my previous set-up, which was not
exactly heavy. The wheel says J'ville Cycles (my sponsors Johnsonville
Cycles), and Stans No-tubes (because it's tubeless). The brake is a
ultralight magura airbrake- weighs next to nothing. Or at least it
will do when I trim off those brake mounts.

I just had a quick spin on my new upgraded Coker- man...talk about
fast! I didn't exactly have a heavy Coker before, but now it's
ultralight and ultraresponsive.

It still rides like a Coker, but you can flick it around on turns and
accelerate away like a race b*ke in the big ring. It's just an
unbelievable feeling!

Basically, I upgraded my frame (saved ~250g), cranks (~200g), pedals
(~300g), Seat (~100g), Handle (~400g).

I don't have accurate enough scales to give a good measure of the whole
unicycle- but on my bathroom scales it weighs just over 6kg.

My new Diet Coker setup:
Coker Tyre, Stans Tubeless conversion
Airfoil rim
Tommy Miller SS spokes
Standard UDC hub
Schlumpf alloy 114mm cranks (~300g vs the 500g 110mm Bicycle Euros I
had previously)
Wellgo MG-1 Magnesium pedals (370g vs 680g for my trusty sealed Snafus)

Schlumpf 1st Generation reject frame (850g vs 1100g for my old Std
Coker frame)
Miyata carbon seat, dual density foam (I haven't weighed this, but it's
at least 100g lighter than my KH Carbon seat with heavy foam that I
used at Unicon).
Wallis Deathgrip Carbon handles (about 400g lighter than the GB4
handle+grips, but I still prefer the GB4. Will swap over for the
purpose of this exercise).

All up, it's a very significant weight saving- especially the rotating
weight (1/2 a kg from the cranks and pedals alone). Add the fact that I
was already running SS spokes and tubeless, and you are looking at 1kg
less rotating mass to the equivalent Airfoil Coker with standard spokes
and tube set-up. Add a bit more if you are using a wide hub, or even
more if you are not running an airfoil rim.

Anyway, the point I'm trying to make is that Cokers are too darn
heavy....if you lighten it, you WILL notice a huge improvement. It
still rides like a Coker (stable and predictable), but the handling is
just so responsive. This thing rides like a feather. And the
acceleration- really freakin fast. I can make unbelievably tight
turns. I can't wait to take this off-road.

Compared to a standard steel rim Coker, it's like riding an 8kg
roadbike vs a 12kg Mountainbike :p .

Not yet- I've only taken it for a short ride. I guess we'll see how
well the pedals hold up (see the other thread on Wellgo pedals). They
are actually grippier than my Snafus, which actually makes it harder to
adjust your foot position at high revs.
I think this frame also flexes more than my old steel one. It doesn't
matter as my airbrake is capable of adjusting to the flex unlike many
of those lousy hydraulic brakes that people have on their Cokers.

I like my GB4 handle (450g) for distance more than the Wallis
Deathgrips (50g), but it would be ideal as a Coker MUni.

You really have to ride something like this to see what I mean. I took
it off some jumps and up a few bumpy sections and it's really
responsive. It's so easy to hop around things and do rolling hops over
obstacles instead of plowing through everything like a regular Coker.

No not really....probably less so than a say a Hunter Coker would be.

The Deathgrip handle is quite expensive (can't remember how much), and
so is the Carbon seatbase. The frame was one of Florian Schlumpfs
rejected ones so he donated it to me for this project 😎 . The
tubeless conversion costs a bit (?about $100USD from memory), but then
you can use the sealant and rim strip many times over. Pedals I got
for $99NZD- less than what I paid for my old Snafus'. And the cranks
are about 25CHF. The spokes were pricey- I think ?US$2 a spoke from
memory- they were handmade by Tommy miller. But you can get cheaper
and probably better Stainless Steel spokes from Unicycle.com now.

What are you using for the dual density foam?
I'm still on a quest for a more comfortable Coker seat and am looking
for new foam ideas.

John,

I'm using some foam that Scott Wallis sent me. It was trimmed at the
nose and tail in order to flatten the seat further.

Unijesse,

I don't think it's the wheel- I think the frame is slightly bent. Why
do you think Florian rejected it? :p He sent two batches of frames back
to Taiwan before giving up and making them himself. Anyway, it's still
lighter than my existing frame until I get a custom frame made up. And
I got it for nothing.

More likely the frame's slightly wonky. Nothing a bit of shim won't
sort out.

Looks nice Ken - I'm starting to get very tempted by cokers.
