One ounce equals 28.35 grams.

That's silly: why go to the trouble of removing all the RD material, and not cutting off that long heavy cable end? Heck - drill the cable too while you're at it.

That kinda looks like the one D. Dude did, that broke. There are, of course, diminishing returns depending on how much material you remove. I'm going to try my first drilled component this winter. First since 1977 that is, when I did a couple chain rings with a hand drill.

Yes, my point though is I would need a gram scale to give an exact weight difference, not just be able to say, " about an ounce".

Multiple delusional bidders !

Anyone who drills crank arms is a few balls short of a headset.

thank god ....it only sold for 50.00

Interesting - I think that's the second completely-hollowed-out NR rear I did (I kept the first). It was done for my buddy in WA in West Seattle; he told me he passed it on to a guy in Japan IIRC. This pic is obviously after he passed it on, because my buddy was a gram-freak and cut his cables right up against the pinch-bolts and didn't even cap them.

Funny to see this old thing (only the second ever example of my drillium) so many years later. He rode it for a couple years, btw

Answer: 9 years and counting

It's true - I milled this for a buddy of mine who ran it for a couple of years on his Gios. I found out a couple years ago he passed it along to an enthusiast in Japan (it appears this photo shows the RD on the Japanese guy's rig).

Only my second-ever attempt at drillium, too

I stand corrected then, D. Dude. Wasn't there one very similar to this, where the front plate busted in half? Or, maybe that wasn't one of your pieces???? I think you posted a pic of it not too long ago.

No, you're correct - one did break. It was number 3 and I just took a tad too much out of that one. But my original and number 2 (in the pic above) have held together. I used mine for about 200 miles, and my W. Seattle buddy probably put a couple thousand on his. I don't know if the new Japanese owner of number 2 is putting it to use as a user these days.

Personally, after number 3 snapped in half, I retired number 1. It sits on my display shelf right here in my room on DG today

To my eye, I'm surprised any of them lasted! Looking at that pic above, it amazes me. Especially that area where the end of the spring sits. Looks so fragile. It just goes to show the power , and strength, of forged aluminum I suppose. Nice work, BTW.

Note that where the spring contacts the alloy there is a little channel routed out. Did this to ensure the spring moved freely without binding. Also note that in the normal derailleur, only the top of the round portion rides against the underside of the outer plate; in my hollowed-out version, the load is spread evenly on the two "rails". While I simply wouldn't trust it under really heavy power shifts or for a long-term option, it does still function the same way as before the drilling.

As for the failed one, well, it was just subjected to a load unlike what it would experience during use while being assembled. In any case, lesson learned. I only did two more (with simple drillings on the back plate) with a hollow front plate and sold them on Ebay a couple/three years ago. I don't think I'll be doing any more unless someone commissions one. I did that for Poprad, for example.

AFA weight savings, aluminum skewer nuts would be a lot better bang/buck. But nowhere near as cool as well-executed drillium.

2 people actually bid against each other to get it!!!!!!!
Drilling creates more drag with the holes, so cancels out any weight advantage, then you have a weaker item for no advantage.

Speaking of balls, I wonder if any of these T-Gear post went south.... ouch.

Are those posts notable for anything other than being not so attractive? I've had one for years, never can find the right bike to put it on..,,,,BF

Is he related to the guy in Poland who put his "Pantographing" on Ebay? I tried to point out that his freehand engraving looked as though it was done by somebody with the DT's and he accused me of being racist towards Polish people. When I told him my wife was part Polish and I was just prejudiced against sloppy workmanship he gave a similar answer to the guy above.

Sign of the times these days - too many people are going high and right when it comes to taking offense to things

And he's now selling über-rare Shimano 'XO SWEPE' (ADAMAS AX inverted, minus an 'A') first-gen aero levers. What a maroon.

Send that lobotomy expert a BMX rear sprocket and ask to have it drilled. Those things are hard and will dull all his drills.... LOL
