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:
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.
Ben Being a weight weenie is a bit foolish, but I don't know what to make of a weight weenie who can't count.

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

"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:
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!

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

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.
I assume you mean the pedals, not the cranks? FWIW, Zeus started in the bicycle business almost a decade earlier than Campagnolo. jim beam <[email hidden]> wrote: > it does look quite eye-catching though. "beautiful" even.
Gadzooks! It even has the ever popular 13,13,13,13,14 freewheel. But what is up with the clipless pedals! If you are going to ride the retro circus bike, you have to get some Campy quill pedals and super cool toe clips/straps. Benotto checkerboard celotape, too -- and a cell phone so you can call for a ride when the crank breaks. They break even if you don't drill 'em.-- Jay Beattie.

Yep, Record Superleggeri pedals with A.L.E. chromed toeclips were on 'em new [1]. That's Italvega's _factory_ mod too, not just the efforts of some home drill whacko!
I saw a line of them, all sliced and pierced, at Ben Olken's Bi-Ex in Boston and just froze, agape.
[1] this was well before aluminum toeclips. Or Benotto Celo Tape, Italvegas had real Gaslo tape back then. -- Andrew Muzi <www.yellowjersey.org/> Open every day since 1 April, 1971 ** Posted from http://www.teranews.com **

unfortunately, that's the truth. i've only ever seen one of that vintage crank uncracked at a swap meet - and that was n.i.b. everything else, always cracked where the arm meets the spider. a couple of dozen now, every single time.

I broke four or so NR cranks. Jobst broke like a dozen. We shopped at the same store -- Palo Alto bikes -- that had dozens of NR crank arms on wall racks. You would just step up to the counter, hand the shop guy the broken crank arm, and he would go to the wall and give you the appropriate replacement. PAB did not have a 177.5 crank arm when I went in one time in the '81 or 2 and believe it or not, I still have a credit slip for $35. I could buy half a good tire. -- Jay Beattie.

The first time I recall seeing an all Campy bike -- a Motobecane -- was in '69. Barry Wood, Phil's son, was going nuts about it. It belonged to a music teacher subbing at our junior high. I could not imagine being that excited about a modern bike. Back then, touching a Campy side-pull was like a religious experience. -- Jay Beattie.
