What Will Be The Latest Diet Craze For Bike Parts?

It looks like we're about due for a wave of insane measures to save weight on bike parts.  Of course, some might argue that we are in one.  In any event, it seems that such a cycle comes every other decade. 

In my cycling life, I have witnessed two such bouts of insanity. The first came during the '70's.  Those of you who weren't into cycling (or weren't around) then probably remember other ridiculous fads like disco, droopy mustaches, pastel-colored suits and mood rings.  Well, in cycling, there was something almost as absurd:  an attempt to turn seemingly every bicycle part into a wedge of Emmentaler (or, for us Americans, a piece of Swiss cheese).

  
 Ah, yes, drillium.  I remember it well.  Along with it came slotted brake and shift levers.  Ironically, Campagnolo's cut-out Super Record brake levers actually weighed a few grams more than their smooth-surfaced Record levers.  A company rep said that Campy made the material thicker so to make the levers safe for slotting.

Along with grunge rock and "indie" everything (To me "indie" meant, in the '90's. more or less what "gourmet", when used as an adjective, meant in the '80's:  "pretentious".), the final decade of the 20th Century took slotting one step further.  It seemed that every kid who had an Erector Set as a kid came of age during that decade and either made bike parts or opened a "high concept" shop that sold them:

What will this decade's insane attempt to save a gram bring us?  I would argue that it already gave us one such trend:  almost everything made of carbon fiber.  Now, I can understand why racers would want a carbon fiber frame, and perhaps even a set of wheels--as long as his or her sponsor is paying for them.  But a carbon fiber seat post rack?  Any kind of rack made of that material?  The day we see a carbon fiber GPS system for bikes will be the day when, as Pere Teilhard de Chardin said about the Hiroshima and Nagasaki bombings, technology has triumphed over reason.

When You Have A Couple Hundred To Blow

You can't make this stuff up.

Believe it or not, at least two companies are actually making carbon fiber racks that clamp on seat posts.  They both look something like what you see in the photo.


Bontrager and Topeak both claim that their versions of the carbon-fiber seat post rack can support seven kilograms.  That's reasonable enough, I guess:  If I had a seatpost-mounted rack, I don't think I'd want to put much more weight on it.  And, if I were going to carry panniers and camping equipment, I don't think I'd be using any seatpost-mounted rack, whatever its material.


Then again, I don't think I'd be using anything made of carbon fiber if I were carrying much more than a spare tube and a multitool on my bike.  Actually, I don't have, and don't plan to install,  anything carbon fiber on any of my bikes.   Whatever weight savings those feathery tidbits might offer would be negated by the weight my body is storing, as bodies are wont to do when they reach my age.  And the carbon-fiber weight savings would certainly be nullified by, say, saddle or pannier bags, let alone what anyone might put in them.


And although failure is relatiively rare in high-quality bike parts and accessories, I wouldn't want to take the chance of breaking any carbon-fiber part or accessory. Carbon-fiber tubes are particularly nasty when they fail:  They break along a jagged edge, like a glass bottle.  And carbon-fiber edges are as sharp as those bottle fragments.  If a carbon fiber seatpost were to fail, having an uncomfortable saddle would be the least of my worries.  All that beautiful work Dr. Bowers did would certainly be for naught!


Of course, a broken rack wouldn't have the same consequences.  But things could get ugly once that broken rack and its contents fall into the rear wheel.  And if that wheel is made of carbon...


Maybe I'm just getting old and cranky, but I still think that fiber belongs in cereal and carbon in filters.
