There Was An Old Lady


There was an old lady who swallowed a dog,
Oh what a hog, to swallow a dog!
She swallowed the dog to catch the cat,
She swallowed the cat to catch the bird,
She swallowed the bird to catch the spider,
That wriggled and jiggled and tickled inside her,
She swallowed the spider to catch the fly,
I don't know why she swallowed the fly. Perhaps she'll die.
-Traditional Children’s Song

In the wake of the UCI’s proclamation on lawyer tabs, one compliance solution suggested is to develop long-throw quick releases. By tweaking the cam action, you can make a quick release that opens wide enough to clear the lawyer tabs and closes farther when the lever is thrown, cutting down on any adjustment of the quick release nut. With it, pro teams could be in compliance with the fork tab rule, but still preserve quick, safe front wheel changes. Leaving aside questions of leverage and clamping force, etc., it seems a logical enough solution. But I like a good rhetorical rabbit hole, so let’s jump down this one…

Since teams cannot modify equipment, per the UCI, they wouldn’t be able to take a file to the cams or otherwise modify their existing quick releases to achieve a longer throw. Someone would have to manufacture a new lever. The manufacturer of that new lever may or may not be a team’s wheel or component sponsor. Given the situation, a little non-sponsor-correct equipment might not be the end of the world, but it’s not terribly comfortable, either. It’s one thing for a Campagnolo team to be seen using a boutique manufacturer’s quick releases to solve a problem in the near term, it’s another if they have to use Shimano.

But what manufacturer, boutique or not, is going to develop and manufacture a new, presumably high-end lever solely for a market that very much prefers to either get its equipment for free or be paid to use it? The world is rife with bad business models, but it doesn’t take much to spot that this one is not a winner. So you have to assume that whoever goes through the trouble of making long-throw levers for the pros will put them on the consumer market – capitalizing, of course, on their use in the pro peloton. Meanwhile, in response to sponsorship discomfort and be-like-the-pros consumer market pressure, Campagnolo and Shimano and SRAM and whoever else will have tweaked the throw on their quick releases, and, since making two versions of something as mundane as a quick release for pros and consumers makes little sense, long-throw quick releases will become the high-end consumer industry standard.

So, through a minor feat of engineering, we’ll have widely available quick releases that, when open, clear the lawyer tabs currently found on pro and consumer bikes alike. Problem solved. Until someone in the Reflector & Fork Tab division of some consumer protection agency realizes that the lawyer tabs on forks no longer even remotely retain the wheel when one of the new, now-standard long-throw quick releases is left open. Know what happens then?

Lawyer tabs get bigger. And then we'll need longer-throw quick releases.

I don’t know why we swallowed the fly. Perhaps we'll die.

Dude... awesome. And true.

FWIW, I'm pissed about the sock length rule. Wondering if it affects USAC MTB races. See, I wear knee socks b/c I get a profound allergic reaction from just a tiny bit of poison ivy exposure. A touch on the shin quickly results in boils everywhere. Yep, *everywhere*.

Only precludes me racing in a couple races locally since MTB'ers wisely kicked NORBA/USAC/UCI to the curb in favor of grassroots racing, but still.

TW: Alisi Shibure. I think they make Kierin lap bells.
 
I tweeted the same thing when I head about this.
Cam spacing and lawyer tab arms race!
