Nimbus 36er build questions

Hey, I'm trying to do the same thing, but my project is on hold because
of the airfoil rim and tire issue. It is true according to another
post, that the new coker tire will blow off (unpredictably) of the
newer airfoil rim. I've talked Roger at Unicycle.com in the UK; he has
researched this problem extensively. Apparently, the new airfoil rims
were made slightly smaller than previous batches while the recent batch
of coker tires were manufactured 2 millimeters bigger. It's a
complicated problem for either manufacturer to set up new
specifications and produce a new batch, so there is no solution over
the next several months.

I had looked all over for an old airfoil rim (already bought the coker
tire), and found one in the UK, but shipping alone is well over $100.

So, I'll probably put the coker tire up for sale on eBay. Maybe
someone with an old airfoil rim would like it. Then, I'll have to
settle for a wheel assembly with the new airfoil and the radial TA
tire.

1) Can you really not fit the coker tire on the "X" airfoil rim? I know
UDC -says- the rim is too small, but does it work anyway?

Computer says...nah..

2) Is it possible to build a coker wheel in a standard Park Tools TS-2
truing stand? Any mods I can do to make it work?

I attached a pic of my custom extensions, made from old bearing caps
and steel bar. Works for me.

3) I've heard talk of putting 29er tubes in coker tires....but I
haven't heard many details or success stories. Does this actually work?
I was looking at the WTB 29x2.1" on UDC. It'd save me like $31.

Computer says...YES!

Where did you get those cranks? I would like a set

thanks for the responses....

I'm glad I'll be able to build the wheel myself.

Now, I just have to decide whether to get the dwarf airfoil rim and be
stuck with TA tires for life, or wait for an indeterminate amount of
time for a good rim.

The decisions even harder because I want a coker.....NOW!! my friends
and I got the okay for starting a unicycle club on campus, and I'd love
to have it for the first meeting in a couple of weeks. 🙁

Yea, those cranks really looks nice. It would be nice to have cranks
like that.

And I think that it isn't that bad to use TA tire. It last longer and
there's better rolling.

The TA tire is probably okay to be stuck with. Personally though, I
don't like it as much as the Coker. Sure, it's smoother on the ride,
but it's heavier and it lacks tread. I know there's the options of
cutting sipes into the tire, but this just seems too much trouble and
requires too much down-time for an expensive tire.

I'm going to wait until I find an old rim or until a new batch of rims
or tires come out that properly fit each other. In the meantime, I'll
be getting good practice by trying to keep up with my 29er.

Good luck to you on your project.

Those look like Davinci cranks.

I made some of my own that worked very well.

I was looking at the WTB 29x2.1" on UDC. It'd save me like $31.

It is possible to use a 29er inner tube but it is really hard to mount
the tire without puncturing the tube. I know of several people who
punctured 2 tubes before successfully getting a third working (and
others who gave up after several attempts). In other words it may not
actually save you money if you have to fork out for 3 tubes.

It may be a better idea to consider a tubeless kit. This should be
easier to get mounted and may not be too expensive.

Regarding the 36" tubes.

They're $38 at UDC, but I found them on coker's website for $15.50

DUDE!! the tube is 3 pounds? crazy...and I wonder why UDC found it
necessary to mark up the tubes over 100%?

Cos they like to make money? 100% mark up is pretty standard for shops.

but I'm sure even the coker tire shop has it marked up pretty well, too.
and $38 for a tube is ridiculous.
