My new favorite (again) uni accessory

Hey Tom,

Great to see your having so much fun with those cranks.

Sorry, I missed the initial thread about these(if there was one), but
can you tell me if PDC did the drilling, or did you go to a shop up in
your neck of the woods for the drilling of the additional hole?

Are Kookas, the only cranks you can do this with? I know there hard to
find.

I ask only for my own curiosity. I still don't have a Coker, but the
concept intrigues me.

Keep rollin!!

Cheers.

Nice. The Espresso Mojo is feeling a little long in the cranks now.

How well did the extra hole fit on the Kooka cranks? Picture of the
new hole?

There were actually a couple different threads started by pdc on this
topic, but the original one 'is here'
(http://www.unicyclist.com/forums/showthread.php?t=48361). Do the
"find all threads started by..." thing and you can see some of the
other discussion. In all cases, pdc helped arrange for the drilling
via a very skilled machinist. I thought about having the fourth set
done locally, but decided it was not worth the risk, so sent them back
to the original machinist and have no regrets with that decision. I
think there are other cranks that would be okay for multiple drillings,
but it's not something I've ever researched. I hadn't thought of the
concept at all until pdc's thread came along, after which I could think
of little else. 🙂 You can still find Kookas on ebay and other online
sources, but they're getting rarer. PDC just ran into a nest of them
somehow, and was nice enough to secure the lot of them for the
unicyclist community.

It fit perfectly...the outside of the hole closest to the hub exactly
touches the "bend line" where the plane of the crank's surface shifts
slightly. I was too hopped up on pho when I did the job today, so
forgot to take pictures of the cranks before they were mounted. We can
pull the pedal for an official JC inspection as soon as we get together
for that saddle-building session. This weekend perhaps?

The new '2008 DualCross Pro' (http://tinyurl.com/2kkfb7) with the NiMH
battery. They also have a diffuser option for the DualCross Pro now.
The diffusers are lenses that stick (adhesive) to the stock lens and
give a more wide angle light spread. Wider angle spread with an LED is
nice. Very few LED lights have a wide angle option. I just got the
light. I'm waiting on the helmet mount to get here (had to order it
separately).

Tom,
They look great. Keep your shoe laces tucked in. I haven't actively
looked for old Kookas in a while. Were I to find some sets, I might do
another round of them. If the Isis hubs become a 36er standard or
option (is the Quax 36er Isis?), then the 2 hole KH cranks (125mm
150mm) would be very nice. If someone else comes up with some they need
drilled I or Tom could put them in touch with a machinist. He has a jig
made specifically for drilling that make of Kooka cranks. I have the
tooling (drill and taps) and could make them avalable.

be bothered to look for them though.

If you are, can you put my name on the list? I have an original
square-tapered Schlumpf and thus cannot have the further flexibility of
the KH dual-hole cranks, so those multi-holed Kookas would be the only
way to do it.

Trouble is the small matter of getting them to me, as I seem to be on
the wrong side of the Atlantic pond.

Clicking the gold button is a cheaper, quicker and more effective way
still 😄

Well, getting towards -the -length anyway... surely 100s are -the
-length!

How do you find the large amount of extra crank spinning next to your
heel? At 110s setting you must be going quite fast - is there no fear
of catching them on your foot?

I don't call an £800 Schlumpf hub a "cheaper" solution.

- I never saw that thread first time round, so "remember this" is an
invalid question.
- Not all of us have the manual dexterity to put a shelf up, let
alone machine holes into existing cranks.

You already have the £800 Schlumpf. Clicking the button costs nothing.
Things don't get much cheaper than that!

I thought the thread was about finding a machine shop or bike shop that
could put threadded holes in cranks. The point being that there are
other options to buying pre-drilled Kookas from the USA.

Thanks Sam...you are one of a few people that have inspired me to go
shorter. I'll look at the 100s after I have the 110s wired.

I have had zero problems with "the nub" while -spinning-. The only
place it comes into play is during mounting. If your foot lands too
far in on the pedal and you don't adjust before the first trip around,
the nub can knock your foot off when it comes around. The good news is
you don't have any speed going yet. The bad news is it makes you look
like a klutz whilst mounting, but that is something I made my peace
with long ago.
