PS or CdM?

Cdm

I do have two rather awesome bikes previously owned by the well missed PS. He had exceptional taste, and I dare say a lot of my preference comes directly from those two.

FWIW-

I do have a few cranksets with lots of holes in them.







I think they're very pretty- and nifty for the novelty and aesthetic factor. I don't so much care about any weight factor.

What about this Drillum home job? Not saying that I could do better, but the diameter of holes seems too large and spacing is off. I like Super record style factory drllum levers--good spacing and small holes. Not really sure what the Seller was thinking here. Seems like could lower value of nice stock Campy un-drilled levers unless job was really good. I would practice on cheapeez levers and then gauge results.

Although I have seen some lovely pieces, I personally, am not the least bit interested in having anything drillium on any of my bikes. That is not to say it is wrong, only stating that I am not a fan. In my mind, I do not want a single component to draw immediate or too much attention. I like to see the whole bike and then start looking for detail. Drillium immediately draws one's attention, in my opinion...



As for a value increase or decrease, my guess would be increased value to most people. Needless to say, as stated by others, the drillium must be nicely done and not done to the point where it will negatively impact safety.

This does not make me holier than thou, though!-)

Also the "Mighty" Sugino Mighty Competition and Super Mighty Competition as well could be had drilled in black and silver. All of them being every bit as strong, tough and excellent looking as any other IMHO.

That '74 GC has what appear to me cranks off an close to same time Ital-Vega superlight.
Personally, scary. But if you want to recreate that bike from a frame, there you go.
I have purchased some "period" or at least period looking drillium parts here and there for effect. Thankfully they went cheap.
I have a few "factory" drillium chainrings, if I were to need to sell those I would expect a premium. Everything can be replicated, but at what cost?

I find anything other than top level work (as shown by Drillium Revival and Drillium Dude) to be unattractive and think it lessens the value of the part. Some of the exquisite work done by the above mentioned practitioners I would pay extra for; they not only have great technical skills but they also don't get excessive to the point that the structural strength looks seriously compromised.

paying extra for a structurally compromised part is faddish.

You can find failed examples of brake levers, FD bands, crank arms, RDs, anywhere you search drillium.
I don't consider my chainrings disposable, but not so structurally sensitive as the other components listed above.
(Factory drilled brake levers are not drillium)

I'm ambivalent about drilled parts. While I agree that D. Dude and Otis do excellent work, the best I've seen, I generally prefer my old Record parts in their original state.

However, I have considered doing a chain ring. Just to see of I can use my rotary table properly.
Never done it before.

Some might say using friction DT shifters on a bike built for ergos is faddish and of questionable value. Most of C/V is faddish and for image/nostalgia.

Drillium represents a trend in an on topic time...and, aesthetically, it's interesting stuff. It was influential enough where parts makers emulated it.

being hunted by the ignore list.
Drillium was faddish then and it's even more faddish now.
I ride my bikes big miles - they're reliable and built the way I want them to Function - it has nothing to do with others.
If there is a reason I take exception with drillium, it's hopefully to talk someone out of damaging their good component.

Also, there is nothing about this frame that was designed for brifters

For me, if it came original like that then it is ok.(evidently, OEM is not Drillium) It also is limited to flattish parts such as dropouts, chainrings and brake levers. I do like DT shifters that are more or less a hollow frame. If they just had holes drilled in them they would look goofy, though. I think most any component with holes drilled along the structural frame edge are hideous, especially RDs. RDs with holes on the cage plates just says ruined to me. It does not matter how good the work is either. In the OP's example, so many of the holes are off and easy to spot. That ruins it for me. Hopefully, the FD does not have holes on the arms that hold those plates.

My first and only attempt at drillium. I think I did these about 1977 or so.
By hand. Didn't own a drill press back then.

That looks fantastic! Not overdone, tasteful...really nice work man. I wish like heck I had any ability in the industrial arts.

... or a saggy dangle seatbag or a coffee cup holder, but who notices?

I have some longer housing and cables that would fit the Moser if you need it.

Thanks KAS. Someone here bought the small one. Still have the big ring and may use it, just as an experiment, to see if I can figure out how a rotary table works. Setup is critical with one of those...and I aint no Otis. But it might be fun.

the bike functions with perfection and the Randi Jo bar bag is for wallet, keys and cellphone
I'll always get home without anyone's assistance.
you don't have to like my bike, and you're welcome to drill your parts, but don't expect it to improve reliability

The bag may look saggy, but it's rock-solid. It's complete roadside with tire, 2 tubes, 2 oz Stans with valve cores and Tufo tool, leftover chain piece and links, tool for every fastener and small rag. It's still the lightest of my 3 bikes. Yes, it's the opposite of drilliium - it improves reliability.

Factory drilling on brake levers is also functional - it improves grip for single-finger braking.

I don't have a problem with the Spanish Zeus 2000 mastercraft drillum work. Would love that RD and crankset on a bike.


This Italvega looks like a nice factory drillum job on drop outs. Since that is on the frame and not just a brake lever or chainring--better be done right. Anybody think that could do anything structurally to the frame?, nice factory job or not.

Drilling the dropouts adjacent to the adjuster screw will under a catastrophic drivetrain issue may show the weakness there.
Under normal courses of use, not a problem, I have a number of bikes with various milling or drilling of the dropouts. I don't worry.

I guess that is why everyone has an opinion. The crank looks cool, but those holes sure are close to the bottom edge of the chainring. What happened at 11 o'clock? The driller wasn't watching what he/she was doing. The RD, no. I would rather have something cut out of the Z plate. Not feeling the dropouts either. The holes aren't uniform. That one that sticks out of the chrome zone makes it look like a garage job. Drillium is just not my thing.

Do you have green to match the tires?

You can even find some examples where cranks have broken at pantograph edges, so it doesn't take an awful lot to produce a stress-riser in a highly loaded aluminum part.
