Drillium Is Not Enough

bjw@mambo.ucolick.org

Forget back to the future. Let's go forward to the
past. Ebay is a silly place, but sometimes it provides
a laboratory to observe human behavior. I present
Chalo's new favorite crankset:

http://cgi.ebay.com/SKELETONIZED-Sh...1QQcmdZViewItem

or

For people who missed Topline and Sampson
cranks the first time around
http://www.bikepro.com/products/cranks/sampson.html
you can machine them yourselves. Although,
even Sampson wasn't clinically insane enough
to machine out the _center_ of the crank arm.

Ironically, the seller seems to be including an
American Classic BB that weighs 285g (?? it's
not even titanium!) which must surely cancel
out the weight savings from cutting out all that
aluminum from the cranks. I didn't know
American Classic made anything so brutally
massive. Campy high-end square taper BBs
and Shimano UN-7x were lighter than that.

This is old, was done already - many years ago (1975 Zeus 2000).

I like it, especially this part:

"The drive side has been skillfully machined, while retaining all of
its strength while losing about 100 grams."

It's just like Shimano to overlook such an easy way to shed weight
while retaining all the part's strength. Maybe this "wayshwing" dude
has a patent on his innovation, and they are waiting for it to
expire. :^)

It reminds me of Stronglight Pulsion cranks-- another astounding
idea:

http://www.gottaridebikes.com/Merch...ct_Code=RCR0006

Anyway, you know how I love welded steel cranks. This extra special
eBay seller has inspired me to make a set of geodesic space frame
cranks welded up from segments of spokes. Stay tuned to eBay where I
should be able to sell them for a fortune!

Or the slashed and cuisinarted Campagnolo Record arms on the 1972 Italvegas!
The "Renzetti" versions were actually pretty!

Dear Chalo,

Here's one method for making a light, strong steel crank, patented by
Southard:

http://groups.google.com/group/rec....0db190a756ae909

It actually worked.

Cheers,

Alas, there's no mistake so mistaken that it can't be
made more than once.

From these pictures:

http://www.classicrendezvous.com/Sp...eus2000comp.htm

http://www.classicrendezvous.com/Sp...2000_cranks.htm

I gather that the Zeus 2000 where the crank
relief was drilled all the way through was a
less common variant. When it's not drilled
through, it's a bit like the typical crank relief
from those days that ran down the arm, if a
bit more so.

Drilling the crank all the way through, aside
from all the exposed surfaces for crack initiation,
significantly reduces the stiffness in certain
directions (and more bending means greater
likelihood of crack initiation).

What surprises me about the ebay drilled-out
105 cranks is that the chainrings weren't
modified. Zeus would never have let that
opportunity pass by.

it does look quite eye-catching though. "beautiful" even.

Bolt circle is much smaller, accepts a 36t ring

I assume you mean the pedals, not the cranks?

FWIW, Zeus started in the bicycle business almost a decade earlier than
Campagnolo.

Some people even did it to their Campy cranks, since Campy wouldn't do
it at the factory like Zeus did:

Ahem.

Also, you need to machine out the reliefs in the crank arm and the
spider, and then check your medical insurance.

That is actually quite pretty, at least to me.
