Riding in the wrong direction

First off, congratulations are due to Alice Lethbridge on breaking Beryl Burton's 1967 record for longest distance cycled in 12 hours. A 12-hour ride is a serious physical challenge.

On a social media comment thread, I took some serious jabs for pointing out that the carbon fiber spaceship Lethbridge rode is a far cry from Beryl's 1967 rig. Some riders got what I meant, but the modernists called me an "armchair cyclist" and a "bellend." While I do love British insults, the modernists and the worshippers of competitive achievement miss my point, as usual.

Maybe the problem is the way records themselves are recorded. We get a name, a date, and a distance or time. The format itself implies equivalence in all other factors. If that were true, then the entire aero bike segment of the industry is a giant scam. If it's not a scam, then the bike needs to be featured prominently as a huge contributing factor. Yes, it diminishes the athlete. Athletes accept diminishment all the time for the sake of technologies that will make a grueling task slightly easier. One would expect -- all athletes being equal -- that improved technology would make records fall at regular intervals. But Beryl's record stood for 50 years.

took 50 years to beat this:

There have been plenty of intermediate steps in aerodynamic evolution. No rider in all that time managed to exceed the performance of the phenomenal Beryl Burton. That leads to another point: If records are the province of phenomenal people, what do they really mean for the rest of us? They indicate a high point attainable by the right person with the right training, and they give us something to say gee whiz about. But athletes will perform on whatever is available. I bet if you compared the relative prices of Beryl's bike and Alice's, Alice's would still be more expensive, even allowing for inflation. How does that trickle down to the majority of riders?

In automobiles, evolution led to vehicles that are lighter, faster, more fuel efficient (sometimes), flimsier, harder to work on, and basically disposable. Early cars were made to stand up to the abuse of the roads they had to use. Later, the makers still stuck to the old standard under which people built things to last. Only decades of consideration led to planned obsolescence and relentless marketing. I guess it makes sense, when an industrialist has invested in a factory to produce millions of units. You want to keep that line rolling.

Automobiles are very rewarding to the average consumer. You sit in a comfy seat. You control a powerful engine. You can have climate control, an entertainment center, and arrive at your destination smelling about as good as you did when you left home. We've been trained to expend thousands of dollars on our rolling couches, and designed a whole system of plumbing through which to flush ourselves at the best speed attainable by our mechanical conveyances. That speed is influenced by the number of other conveyances in a given pipeline, not just by terrain and weather.

Bicycle designers have taken up the idea that the bodywork should obscure everything else, because air drag is the ultimate enemy. Even in bikes not designed solely to race against the clock, as much as possible gets stuffed inside. Most riders don't do their own work. I've asked before, and still not answered, whether most riders who seem hard core and fully committed only do it for the ephemeral lifetimes of one or two of these modern crustaceans.

Conspicuous consumption is one of the great shames of industrial society. There's a serious parallel to income inequality in a recreational bike that costs thousands of dollars versus a sturdy, durable ride that can still offer a bit of sporty handling, but also carry a couple of panniers full of groceries.

This summer has brought me the whole range of the modern bike experience: chasing air bubbles out of hydraulic lines, seating tubeless tires, snaking cables through the unseen labyrinth of internal routing, and performing exorcism on some electronic shifters. Meanwhile, I hear the same thing all the time about actual riding in the real world: it's scary, it's hard, and a few hundred dollars seems like a lot of money to a lot of people.

The answer is not just swan-necked, step-through cruiser bikes and crushed stone paths. And it certainly isn't "categories." I have built myself several different bikes for different applications, but they all started from basic platforms. Got a chunky one for the roughest surfaces I considerable reasonable to ride. Built a fixed gear for wet and cold weather. Got a road bike for unencumbered sporty rides. Got a go-anywhere commuter/light touring rig. All steel, all simple, all readily maintainable. That's a lot of options, and I bet that all of them together cost less than one top-end bike in road, mountain, or time trial categories.

Speed at all costs

A triathlete friend of mine is making her final campaign at full Iron Man  distance, in November.

Endurance athletics serve a therapeutic purpose for her. She has also worked as a professional trainer and event organizer, because she wants to share the benefits that her obsession has brought her.

For this last big race, she asked me whether she should invest in a state of the art time trial bike. But the budget she set would not get her a bike at the quality level of her venerable Serotta.

The arms race behind the bike race goes unacknowledged.

A lineup of TT bikes featured on road.cc illustrates the most evolved wind-cheating machines to enable a well-trained rider to go slightly less pathetically slowly compared to any vehicle people are actually impressed with. An absolute nightmare to work on, these ultra-sophisticated machines will set you back thousands of dollars -- in some cases upwards of $10,000 -- to get the full wind tunnel tested package of aerodynamic benefits. And you will still get dropped by a rusted-out Nissan that burns a quart of oil in 50 miles and costs a third as much. Much less than a third if you bought a really expensive bike. Or some twit with an e-bike will come tooling past you, vaping.

When Greg Lemond unleashed the aero on Laurent Fignon in 1989, it made aero bikes socially acceptable. It launched the movement to quit making bikes that looked like they were made by meticulous artisans and more like something engineered by the military-industrial complex.

At first, aero enhancements consisted of streamlined helmets and removable aero handlebars. Bike frames still had round tubes! And lugs! Rider position made a huge difference, established by the clip-on aero bar.

Soon, of course, bars were specifically designed and bikes were specially constructed to adopt each aerodynamic enhancement allowed by the governing authorities. This was also the age of the triathlon, where very little cycling tradition weighed down the innovators, and a free-spending population of willing test pilots purchased the latest implements to gain whatever advantage they could.

In any arms race, whoever develops a weapon first enjoys a clear advantage. Once everyone has the widget, that becomes the new level playing field, forcing further advancements to gain a new technological edge. At the same time, the old ways have been obliterated. When the competition is unlimited and existential, the rising tide of technology represents advancement for the whole species. This is also true in non-military contexts. Take transportation, for instance. Ships evolved sails. Sailing ships evolved through various shapes, swifter or more efficient for their given task, until powered vessels set a new standard in speed and maneuverability. On roads, the bicycle initiated the age of mass-produced personal transportation, but the automobile and its variants soon eclipsed pedal power.

Since we're only racing against each other on our bikes, we could set the standard anywhere we want. Does it really make a difference if average time trial times are a minute or two faster now than they were 20 years ago? It doesn't make the event any more exciting to watch, just more expensive to conduct. When everyone has only the slickest bike they can afford, the margin of victory could be in the wallet, not in the training, skill, and determination of the athletes. Or, if everyone has equally slick bikes, the equipment disappears from the equation. Everyone could be on Raleigh Choppers, or vintage Schwinn Paramounts.

The time trial position is not comfortable. The bikes are not versatile. Some are more aerodynamic than others, in ways that may be hard to tell by looks or price tag. And, as I said, they're absolute nightmares to work on. Humans have their urge to excel. There are worse things to blow money on than the pursuit of a few seconds over 40 kilometers. But if all the expense is just to be equal, the problem is artificially induced.

Economies run on induced problems. And maybe the aero bike of today will lead to the pedal-powered personal aircraft of tomorrow. I doubt if even that would spawn an industry strong enough to shape whole political systems and the course of nations, the way internal combustion has.

For now, my friend has to make the best of the equipment she has, with a snazzier back wheel and a new aero helmet, because she lacks the coin to place a much heftier bet on a bike that will turn heads in the transition area. The spacelanders
 she'll be sharing the course with present an intimidating army. The ones that live up to their advertising will actually confer an advantage upon their well-funded (or tapped out) riders. How much of an advantage is hard to say. And is it worth it? That's even harder to say. Ten grand for the ephemeral satisfaction of standing on a podium that will be gone forever, ten minutes after the award ceremony? Or maybe just to achieve a personal best time, down in the anonymous wad of barely differentiated finishers? Look! Here comes that vaping guy on the e-bike again.
