Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Taking the light weight thing too far

Swung by the LBS today to say hi to some guys. While there one of the mechanics said, "Hey you gotta come back here and see Tom's* bike" Now, Tom* is a local rider who has recently gotten into racing and also become a bit obsessive about weight. At first it was getting some light wheels, but now he's gone full-on Weight Weenie. Nothing wrong with that. So, we go into the back and there is his Madone with some trick parts and wheels. Lew Racing wheels, AX Lightness parts, carbon fiber chainrings, the works. Had it down to 11 lbs and change. But here's the amazing part. He freaking drilled out his seat mast. Wonder how long until that thing snaps off and impales his leg. And to top it off, his AX Lightness carbon seat's rails were a bit to thick to fit in the Madone's seatmast's clamps. So he sanded them down until they fit.

*Riders name changed.

Remember, it's always about the bike. And the wheels. Most importantly the wheels. You cannot race unless you have 'race wheels.'

If you're going to do something like that you need to make a jig so that the holes will be evenly spaced.

The point of extreme "weight weenie-ism" is to be able to brag about simple things (things that are inconsequential).

I'm waiting until all the "engineers", physics students, and quasi-wannabe-intellectuals, all come out of the woodwork to discuss stress fractures in carbon fiber seat-masts and create a debate about the most efficient drilling patterns in carbon fiber until I comment further...

Well, I'm not an engineer but in a former life I designed, built, and flew radio controlled sailplanes....layed up and molded my own fiberglass fuselages, cut foam cores for wings with a hot wire, applied wood sheeting and fiberglass to those cores with epoxy and vacuum bags, etc. I might not have a degree but I'm quite sure I know something about stress and how to build for it and:

That's still insane. And if for some reason not from a structural standpoint...it's still insane from an aesthetic standpoint.

+1 - if you're going to drill out carbon at least take the time to do some basic layout. geez.

The drilling pattern "efficiency" can not be known without knowing the layup patern in the mast.

Let's not forget aerodynamics either. There's a reason that seat mast isn't round. Drilling holes in it is ********. Think about the higher air velocity through there as it is diverted around the upper leg.

The owner of the bike is an idiot.

Wait, the holes are for boundary layer control. Yeah. That's it. (See, sailplane experience...)

Oh, and your last point is dead on.

If he does, I'm going to be pissed. It won't matter, because when it goes, he's going to have at least one more butt crack.

Anyone been in it long enough to remember the TA / Campy "drillium" parts?

Some worthy or being called art, some not so much.

I remember that stuff. Bugged the hell out of me, though I joined the sport when drillium was already pretty old. Of course, it has merit.
