Here's What You Need To Climb The Next Hill

Racers and cycling's trendistas (who generally spend more than they ride) have long been obsessed with having the lightest bikes and equipment possible because they've bought into the notion that lighter=faster.  Now, it's true that a lighter bike is easier to accelerate, all other things being equal.  However, once a bike reaches a given speed, a heavier bike will maintain its speed with less input from the rider: This phenomenon is known as momentum.  But it will also decelerate at a faster rate because of headwinds or other factors.

Anyway, during the 1970s and early 1980s, the obsession with weight led to a fad called "drillium."  It's what it sounds like:  holes were drilled (or slots were cut) into parts to reduce weight.  In most cases, the mass saved--a couple of grams, usually--wouldn't make any difference for any rider save perhaps a time trialist.  

Interestingly, track riders--whom one would expect to be most obsessed with weight-- don't seem to have embraced the "holey" look as much as other riders.  did. If I'm not mistaken, NJS, the governing body for Japan's Keirin racing system, prohibits the practice. And when some companies offered pre-drilled or -slotted parts--like Campagnolo's brake levers--they were actually heavier, if ever so slightly, than their smooth-surfaced counterparts.  The reason, I was told by a company rep, is that the Campy used slightly thicker material to compensate for what they believed was a loss of strength that resulted from drilling or slotting.

That leads me to another point about "drillium:" the parts that were drilled or slotted were usually among the lightest to begin with.  As an example, I've seen Huret Jubilee derailleurs--to this day, the lightest made--with pinpoint apertures in it pulley cages. And the poked and gouged parts were almost always intended for racing.

So, I was surprised (even if I shouldn't have been) to come across this:

Now, the SunTour Vx-GT wasn't porky:  Even by today's standards, it's more than reasonably light for a rear derailleur that can handle a 34 tooth rear cog. (And, it shifted better than almost any other wide-range derailleur made before indexed shifting became the standard.) But that capacity is the main reason why racers and others who rode with narrow-range gearing didn't use it:  If they rode a derailleur from the Vx series, they used the shorter-caged version.

So...I guess someone thought he or she simply had to save weight on the rear derailleur to make up for something he or she carried in a pannier or handlebar bag.  It reminds me of someone I knew who made floats with Haagen-Dazs ice cream--and Diet Coke:  the lack of calories in the latter, she said, balanced out the abundance of same in the former.

What You See Depends On Your Vantage Point

 Philosophical question of the day:  Is a groundhog more likely to see his* shadow as an active cyclist

or as a passenger?

I ask because today the critters didn't get their stories straight:  Punxsawtney Phil, the most famous groundhog, saw his shadow, but our local forecaster, Staten Island Chuck, saw his.  According to Phil, there are still six more weeks of Winter, but Chuck says Spring is arriving early.

Which one glimpsed from the saddle, and which one got his view from a basket?

*--It seems that all of the groundhogs consulted for the seasonal forecast are male.  Does that mean that only they have the power to predict?  Or could it be that it's a big deal when they rise from hibernation because the females have been awake all along?

Helping Healers Stay Healthy

I have passed the Memorial Sloan-Kettering Cancer Center many times, by bike and on foot.  Every time, I noticed two things:  few, if any, bikes parked in its vicinity--and how many people in lab coats or scrubs were smoking just outside its doors.

And I've been accused of "ignoring the risks" for cycling in Manhattan, and other parts of New York City. 

(For the record, I've never smoked, wear a helmet, am fully vaccinated and wear a mask when I'm within a couple of meters of any other person.)

Anyway, I have noticed more health-care workers of all kinds riding bicycles.  As a matter of fact, in the pandemic's early days, I gave the old Cannondale M300 mountain bike I fixed up to someone who works in Mount Sinai-Queens, a block and a half up the Crescent Street bike lane from my apartment. His is not the only bike I see parked in the racks outside the facilities.  

I mention all of this because I wonder whether what I'm experiencing and observing is indicative of wider trends, as they say in academic and marketing (!) circles. The question particularly interests me in light of a story that came my way:  the Mayo Clinic, in Rochester, Minnesota, has been named a Bronze-Level Bicycle Friendly Business by the League of American Bicyclists.  In conferring this designation, the LAB cited "improved bike racks, secure parking rooms and tips for employees to ensure a safe and secure ride to and from work" as bases for so categorizing the Mayo. 

We've all heard the admonition, "Healer, heal thyself" (Cura te ipsum.)  It looks like the Mayo is taking steps to encourage its employees to follow that nugget of wisdom.  I hope other health-care facilities are doing the same--which, I admit, can be a difficult thing to do when perhaps no other profession has so many stressed-out people, especially in a time like this.
