Drillium Saddle... I Kid You Not!

I've had this nice Prolite Saddle with Ti rails just sitting around for a few years.  I rode it a fair amount in the past, but it always ended up being just too much of a pain in my ass.  Too firm under the sit bones.  Saddles have to work for all body types from willow wispy to Clydesdale, so they are usually made for heavier people than I, being a compact size.  I tried it again last week on a 40 mile ride, and while tolerable, I was feeling a dull sitbone ache in the end which was unpleasant.  So I got this idea that if I relieved its plastic shell beneath the foam, made it thinner, it would flex more and be more comfortable.  I got out the Mototool and started grinding away, but quickly found out this would take far too long.  Then it hit me...drillium.  I got out my Ryobi cordless drill, chucked in a 3/16" bit and started drilling through the plastic.  Every few minutes I would flex the shell and noticed it was yielding more than before.  I kept on drilling, I must have put 200 holes in the bottom of the saddle.  I mounted it back on the seatpost and climbed on.  Wow!  Softer, more compliant.  I took a short ride around the block and the concept seems confirmed as it felt much nicer.  This outside the box thinking may have just produced a plush, light (200g) saddle.  Only time will tell.

I'll get back to you on that.  Flash

I should have taken the pic before I put it back on, and I didn't want to take it off again, so apologies for the compromised view angle.  Click for larger view.

Drillium and Other Non-Weighty Matters

Continuing my series of informative parts talks, I now steer you towards the arcane art of lightening your bike parts by reducing their weight.  Essentially replacing mass with air.  The art became known as Drillium---a derivation of drill, as in electric drill, and the added suffix of an element, "ium".  Think Unobtanium, that rarest of denizens of the Periodic Table.  The difference is that Drillium is quite attainable, all one needs is a tool, a design, careful measurement, a steady hand, and a willingness to risk one's health by weakening key bike parts that are originally robust for a good reason.

Back in the day, metallurgy was for the most part fixed in steel frames and aluminum parts.  Titanium was very rare indeed, and carbon fiber, if even invented, was the stuff of military secrets and certainly not available to the world of velomen and women.  A typical good road bike of the time weighed about 25 lbs, and very expensive bikes were down around 21lbs.  An modern entry level bike these days is under that weight.  To get a very light bike back then the weight weenies had to turn to their drills.  Every time a drill bit bites into metal, metal is lost in shavings.  Remove enough shavings and grams, then ounces disappear, then even pounds.  But what is added, in my mind, is art.  A certain delicacy, a jewel-like quality is added that didn't exist before the drilling.  I just love the way it looks.  I'm fascinated by the obsession the craftsman pours into his holy parts.  Books have been written about it.

I wouldn't want this to break off between my legs!

As technology has improved and new materials (alu alloys, titanium, and carbon fiber) utilized for both bikes and parts, things have gotten very light without the need for drilling.  So the art of Drillium becomes a thing of the past.  Or has it?

I sometimes find myself walking the back alleys of Ebay bike shops, and I found something there I just HAD to have.  Drillium headset spacers!  Produced by KCNC of Taiwan, here is a page to some of their other lightweight/blingy/ ultra cool items.

Ok, maybe not drilled out, but machined out, but still, hollow spaces filled with air describes Drillium to me.  So I ordered a set of these as a homage to the lost art.  They will make not a whit of difference in my bike's performance or weight, but rather they represent for me a bygone era, and they are just so cool!  I could have gotten carbon fiber spacers in red, but in my opinion they can't hold a candle to these 6061 alloy masterpieces.  Drillium exists as a commodity to us ordinary consumers.  How could I NOT get these?

Actual  scan of my new spacers.  Can't tell from this angle, but they are various heights: 15/10/5/2 mm sections.  They are wider overall than the OEM spacers, they have to be when you think about it, but this extra width imparts a very cool feature:  once installed, the hollow channels can be seen above and below the stem.  

 Kind of reminds me of this, don't you think?

This view shows the visually exposed channels

It all stacks up in the end

So my new hollowed out spacers are installed and I feel like I am taking a part of the Old World Velo out with me on every ride.  And as with all Drillium parts, I just hope to God they don't break.

Get On Your Bike and Ride!
