Hello, and welcome to I Really Didn’t Need to Know That, an occasional feature of this blog that explores things you didn’t think you needed to know–because you didn’t.
Today’s topic: Spandex!
(applause)
It’s happened to all of us: You’re sitting on a park bench in some bucolic setting, perhaps enjoying an ice cream cone, or maybe a nectarine, when suddenly some dude on a bike rolls up and dismounts. And as he gets off you can’t help but notice that the shorts he’s wearing leave nothing to the imagination. You see everything, right up to and including what the guy had for dinner last night, and the rest of your idyll is ruined.
Well, welcome to the world of spandex! Wikipedia describes spandex thusly:*
Spandex—or elastane—is a synthetic fiber known for its exceptional elasticity. It is stronger and more durable than rubber, its major non-synthetic competitor. It is a polyurethane-polyurea copolymer that was invented in 1959 by DuPont chemist Joseph Shivers. When first introduced, it revolutionized many areas of the clothing industry.
It certainly revolutionized bicycling, while simultaneously repulsing many folks around them.
So why do cyclists wear spandex? Is it because they’re egotistical body subjects? No. They may very well be egotistical body subjects, and thus, wearing skintight clothing has added value, but that’s not why it’s worn. Is it because it’s some sort of health-nut gang-colors thing–separating the ‘real’ cyclists from the ‘wannabes’? Again, no. And it’s not because of the low drag-coefficiency either. Again, it’s a bonus that it’s slippery, but it’s not the primary purpose.
Some of you may have jumped ahead here, and think that the reason cyclists wear spandex is because it’s comfortable. Well, guess what? You’re wrong as well. You’re close, but still wrong.
Spandex is not the most comfortable thing you can wear while cycling. It is merely the least uncomfortable thing. This may sound like hairsplitting, but there is a difference.
First off, spandex shorts are seamless. Riding for any length of time with seams rubbing against your thighs will bring about a rash that would make any baby proud. No seams mean no rubbing means no rashes.
The second thing you may not know about cycling shorts is that they’re padded. In a very specific place, and in a very specific shape. It’s sort of like walking around with a bicycle seat glued to your butt. And it is right up against your butt. Bike shorts are not worn with underwear. Did you know that? Did you want to know that? Sorry.
So: is there a reason for folks to walk around wearing their spandex cycling shorts if they’re not actually cycling? In my opinion, the only reason to do this is if:
- You’re going to be riding again in a very short while and there’s no place to change and/or:
- You’re a really hot chick.
Outside of that, take them off or cover them up. I knew a guy who wore his shorts to church, man. Not pretty. All I could think was “Dude, there’s kids around. Put that thing away.”
And in case you’re wondering: yes, I do have cycling shorts. Yes, they do have the added padding–a nearly half-inch thick swath of foam that hits me where the Good Lord splits me. I wear them every time I ride. Even to work (I bring my work clothes in one of my saddlebags, and change as soon as I get there. Yes, I put my undies on at work.) Actually, I’m thinking about buying another pair. Because nothing really describes the feeling you get when tugging on cold, wet, sweat-soaked spandex on for a nice ride home.
I could try, but that would be something you really, really didn’t need to know.
