There’s a moment every vintage bike person hits — usually late at night, usually after “just one more refresh of photos on the Classic Rendesvouz forum” — when you realize you’re no longer looking at components. You’re looking at artifacts.
Drillium lives in that moment.

| Campagnolo Record front derailleur, expertly drilled by Jeffrey Rumbold |
If you’ve ever stared at a Campagnolo front derailleur and thought, “This is already beautiful… but what if it were also slightly insane?” then you understand the impulse. Drillium is the obsessive, craft-driven practice of lightening (and stylizing) bicycle parts through drilling, routing, and hand-finishing. Done well, it turns utilitarian hardware into functional sculpture. Done poorly… it turns expensive history into a cautionary tale.
I'll attempt to explain what drillium is, why it exists, what makes it compelling, and where the line is between art and “what were we thinking?”
And yes—this is exactly why I built the Drillium Collection on LovelyLugs: to preserve the best examples (and a few failures), because this corner of cycling culture deserves more than disappearing forum photos and half-remembered stories.
Drillium, defined
At the simplest level:
Drillium = intentional material removal from bicycle components for weight reduction and aesthetics.
That “intentional” part matters. Drillium isn’t just random holes. It’s pattern, proportion, symmetry, and restraint. It’s also an understanding — sometimes subconscious — that the object you’re holding was designed in a time when mechanical elegance was the whole point.
Drillium is also a workbench activity. It happened in the light of day, with the part in your hand, when someone said: “What if?” and “Could I?” Not as a cynical mod, but as curiosity — an urge to push the craft.
You’ll see it most often in:
-
Rear derailleur cages
-
Brake levers
-
Crankarms / spiders
-
Seatpost heads, clamps, and small hardware
-
Chainrings
-
Brake calipers and pivots (occasionally, and often questionably)
And you’ll see it in a few different “dialects”:
-
Clean round holes (the classic look)
-
Elongated slots / routing (more aggressive)
-
Pantograph-inspired motifs (Italian show-bike energy)
-
“I own a drill press and I fear nothing” (also known as: avoid)
The era matters: drillium wasn’t “vintage hacking”
One clarification up front: drillium wasn’t something people did to vintage parts the way we might treat “vintage” now.
Drillium happened when these parts were current, available, and culturally dominant — when Campagnolo Super Record Silver was the dominant group, we all saved those empty tan striped boxes and everyone was staring at the same beautiful hardware. It was contemporary experimentation, not a nostalgia project.
And today? People don’t take vintage Campy parts and drill them.
Not the good stuff, anyway. Those parts have crossed the line from “components” into “collectible history.” The risk/reward equation has changed, and so has the culture.
The origin story: weight, ego, and the show bike
Drillium came from a mix of motivations that cycling has always had:
-
Weight reduction (especially when grams mattered because everything else was heavy, except for those 21mm Clement Criterium Setas!)
-
Showmanship (the bike as a statement, not just a machine)
-
Craft identity (framebuilders and mechanics showing what they can do)
In the classic European scene — particularly Italy — there’s a tradition of turning bikes into rolling galleries. A Colnago with pantographed lugs. A custom paint job. A group set polished until it looks liquid. Drillium fits right in: it’s craft you can see.
And here’s the truth: even when it starts as weight reduction, it rarely stays purely rational. The moment you see a perfectly spaced pattern of holes across a derailleur plate, you don’t think, “Wow, that saved 12 grams.” You think, “That's freaking awesome!”
Drillium is not the same thing as “Weight Weenie”
This matters, because these two get lumped together, and they’re not the same mindset.
Drillium is a craft impulse. It’s visual. It’s tactile. It’s about proportion, symmetry, and finish — making the object itself more interesting, more alive.
Weight weenie-ism is compulsion with a hypothesis. The hypothesis is that a gram saved will translate into seconds off a 50K road race or a 10K time trial. So the ritual begins: weigh every nut, bolt, and spacer; swap steel for titanium; spend $100 to shave a gram; repeat until the bike (and the rider) reaches a kind of nervous perfection.
Also complete savings obliteration. Forget rent. Cycling is more important!
There is overlap. Some weight weenies practiced drillium back in the day. But when drillium is driven purely by gram-chasing, the results often look like what they are: aggressive, unplanned, and structurally indifferent. The part becomes a victim of the scale instead of an object of craft.
Great drillium doesn’t scream “lighter.” It whispers “art.”
Why Campagnolo became the iconic drillium canvas
Plenty of components got drilled, but Campagnolo is the reference point for a reason:
-
The shapes are iconic: the plates, curves, edges, and contours are already “designed.”
-
The material tends to be forgiving (within limits).
-
The parts are modular and invite tinkering.
-
The details matter: pivot points, spring tension, cage geometry—people who drilled Campy well usually understood what they were risking.
Nuovo Record and Super Record parts have an aesthetic language that makes drillium feel less like vandalism and more like… a variation on a theme.
Sometimes it even feels like Campagnolo left the parts unfinished on purpose, waiting for someone to take them one step further. At least that's what some believed. I always thought it was perfect as is!
The real reason drillium is fascinating: it reveals intent
A stock derailleur is an industrial object. Drillium reveals the maker.
When you look at a drilled derailleur cage, you can tell immediately whether the person:
-
planned the pattern
-
measured for symmetry
-
understood stress points
-
respected the part
Great drillium feels “inevitable” — like those holes always belonged there. The edges are clean. The rhythm is consistent. The finish is deliberate. It reads like craftsmanship, not like damage.
Bad drillium tells a different story: wandering holes, ugly burrs, random spacing, stress fractures waiting to happen. It’s the difference between a jazz solo and someone falling down the stairs with an instrument.
The line between “beautiful” and “broken”
Let’s talk about the uncomfortable part: drillium is flirting with failure.
The more you remove material, the more you gamble with:
-
stiffness
-
fatigue resistance
-
alignment
-
load distribution
Some pieces are safer to drill than others. Some locations are basically asking for cracks.
The best drillium respects structural reality.
You can push the look without ruining the function, but the part has to keep doing its job.
I think of it like this:
Safe-ish territory (with skill)
-
Outer plates with low stress
-
Non-critical cosmetic surfaces
-
Areas with generous material
“Proceed carefully” territory
-
Derailleur cage plates (depends on pattern and edge distance)
-
Levers (depends on where you drill)
-
Chainrings (depends on design and use)
“This is how you create a story that ends badly”
-
High-stress pivots
-
Thin sections near bends
Anything that affects clamping force or safety-critical load paths
Structural components -- stems, handlebars, seatposts (yes, it's been done...but make sure that your dental insurance is paid up!)
And yes: I include “failure examples” in the collection on purpose. Not to mock them—because they teach. Drillium only stays interesting if we’re honest about the cost of pushing it.
A quick guide to “good drillium” (what to look for)
If you’re new to this, here’s how to develop your eye.
-
Symmetry and alignment — it looks planned.
-
Respect for edges — no “too close” holes.
-
Clean finishing — deburring matters.
-
Pattern matches the part — it responds to geometry.
-
Function preserved — if it shifts weird or cracks, it’s not “art.”
Why drillium largely receded (and why it didn’t)
In the era of light carbon parts, drillium lost its practical rationale. Modern components arrive featherweight and engineered closer to the edge. Drilling them isn’t clever weight savings — it’s usually just destruction.
And of course drilling vintage Campy components that are otherwise pristine, clean and usable...well...the collective membership of both the Classic Rendesvouz and the Paceline will rise up against the driller!
So drillium receded into history, aesthetic, and craft lore—a fingerprint from a period when mechanical beauty and human curiosity overlapped just enough to produce some truly wild artifacts.
Except… sometimes you still get the itch
“Mostly” isn’t “never.”

| Modern drillium, mostly as
mischief: a Campagnolo Record carbon crankarm reborn as a menorah. Yes, it’s as unnecessary as it is irresistible. |
And yes, I realize this is not how Campagnolo intended “Ultra-Torque” to be celebrated. That’s kind of the point.
And for all you haters ready to attack me...the pedal mount was blown on this crankarm!
Why build a drillium gallery at all?
Because drillium is fragile in the internet sense.
A lot of the best examples exist as:
-
old forum threads
-
dead image links
-
private collections
-
auction photos that disappear
-
“my friend had one” stories
LovelyLugs is a place where the images and the captions matter equally:
-
what the part is
-
where it came from
-
why it’s interesting
-
what to notice when you zoom in
-
what to learn from the success (and the failure)
Drillium isn’t just “cool bike stuff.” It’s a lens into a craft mindset: take a good object, understand it deeply, then refine it with taste and courage.
Want to go deeper? Here’s where to start
-
Study derailleur cages first — pattern discipline shows clearly.
-
Compare restrained vs extreme — your taste will sharpen fast.
-
Pay attention to finishing — clean edges separate craft from chaos.
-
Learn the underlying part — stock context makes drillium meaningful.
The Drillium Collection
If this post did its job, you’re now either:
-
fascinated, or
-
horrified, or
-
both (the correct response)
Either way, the photos are the point.
The Drillium Collection includes:
-
ultra-drilled Nuovo Record and Super Record pieces
-
levers and clamps with show-bike flair
-
pantograph-inspired details
-
and a few failures, because craft without honesty becomes mythology

A mischievous closing (because we’re being honest)
The truth is, drillium was never just about weight. If it were, we’d all have stopped at “this is lighter.”
Drillium is about the moment you pick up a beautiful part, hear the tiny devil on your shoulder whisper what if…, and decide to see what happens.
Sometimes the result is timeless.
Sometimes the result is a crack.
And sometimes the result is a carbon Campagnolo menorah that absolutely no one asked for — except the part of you that thinks the world needs more unnecessary objects made with care.
Guilty.
