Wordly Wise
Derny (also spelled derney) – “a motorized bicycle for motor-paced track cycling events such as during six-day and Keirin racing) or motor-paced road races. It is driven by a 98cc Zurcher two-stroke engine and by being pedalled through a fixed gear, typically of 70 teeth on the front chainring and 11 on the sprocket on the back wheel [!!]. The combination allows for smooth acceleration and slowing, important when the rider taking pace is centimetres from the pacer’s shielded back wheel. A coupling between the motor and the back wheel ensures the machine will not stop dead if the motor seizes.[…]
The name derny is now applied to all such vehicles, regardless of manufacturer. It is used by the Larousse dictionary as a generic term for a small pacing motorcycle used in cycle races.” *

Check out the front wheels/forks! The pizza plate chainwheel! Side note – at some point, it becomes easier to go to 2-stage gearing as seen on John Howard’s 152.2 mph bike.

To those of you who may, justifiably, wonder how this squares with my eschew the hydrocarbons/bike evangelism – I’ll quote Wally Whitman: “Do I contradict myself? Very well then, I contradict myself, I am large, I contain multitudes.” Seriously – though I love bicycles and am going to try to reduce my fossil fuel consumption, I do not intend to be a scold or to turn my back on gearheadish gnarlyness.

As regular readers know, I’m trying to re-integrate bicycling into my life as an enjoyable, practical transportation option. Given the ongoing nightmare in the Gulf, I’m feeling pretty evangelical about biking, so I thought I’d see if I could encourage locals (or folks from a distance, if they’re up for a big ride) to come to this Sunday’s NHMM meetup via bicycle. I was inspired when I fell across spoke cards while looking at commuter bikes on Flickr – you can see the results of said inspiration above.
The first 8 people to ride to NHMM get a spoke card on the spot – if there are more riders than that, I’ll have more made up and make good on my offer within a week. If there are less than that, anyone from further away than, say, 20 miles can have one if they tell me that they’ve ridden a bike to and from the grocery store this week (6/6) – knowing my own problems with good intentions, it’s gotta be a completed ride.
A shoutout to the good folks at Infinite Imaging who did a bang-up job on printing and lamination.
Carro de cacería mayor: An Argentine barn find hunting Ford
All it needs is a cadge for the longwings and it’d be good to go. Who am I kidding? I’d drive it as is and be very happy.

Second shakedown ride
One nice thing about transitioning from ‘old guys who get fat in the winter‘ to just old guy out for a ride is that stopping to see the sights is a perfectly reasonable thing to do. I’m not in any particular hurry and if I see something I want to check out, I do.

I saw the Goggomobil Dart in town yesterday and popped by to make sure it was not for sale (it’s not). Out back there was a second Goggo.

Low and Slow

Reduce, re-use, recycle

The title of the post comes from a zine published back in the early 70s (called -anyone? anyone?- Low and Slow) covering the wild world of hang gliding. How wild? Folks were making gliders out of Visqueen and bamboo. I mailed off for a copy – because I wanted to build one – sadly, it’s long gone, though a post here suggests I can reread all the Low and Slows on a DVD. Enough of all that – the point of the post: my bike racing (venue = triathlons) days are done – I’ve found myself wanting a bike I can just jump on and ride (comfortably). My fast but twitchy road bike does not exactly fit the bill. My old mountain bike, however…
So, let the conversion to two-wheeled Vista Cruiser begin! IMHO, there are 2 things that determine 90% of overall bike ‘feel’: frame geometry and tires. You’re not going to do much about frame geometry – about the only thing you can alter is the front fork and that costs $$$. Tires can make a surprising difference and unless you’re racing (in which case, why aren’t you running tubulars?) fatter ones than current fashion dictates are what I suggest. Here’s the bike – after the pic I’ll run through current and planned mods.

‘Fatter tires’ is relative – although they’re much thinner than the knobbies that I took off, these are fat road rubber. They’re Kenda Kwests (the 100psi variety) – a nice balance of volume and low rolling resistance. I also mounted a rear rack and put on new, longer grips – I like riding with my hands close together, as if I’m up on the flats on a drop bar. The shakedown ride today was a success – the bike rode like a dream.
I haven’t decided whether to move pedals over from the road bike to this beastie – I’m leaning towards yes. The road bike’s saddle will probably come over at the same time. After that, the next order of business will be handlebars. I have an On One Midge ready and waiting, but because road handlebars are not the same diameter as mountain bars I need to replace the brake levers (not too $$, and I wanted to do it anyway) and swap the thumb shifters for barcons ($$$, and though I LOVE bar-cons, I would have made do). The other short-term priority are shopping bag panniers – the grocery store is within easy biking distance – ’nuff said.
Down the road a bit, I’d like to tweak the drive train a bit. I don’t know whether the chain stay will accommodate a significantly larger middle chainring, but if it will I’ve always been partial to half-step setups – with the triple it’d be a half-step plus granny (and contra Mr. Brown, I’ve used a half-step setup successfully).
Way down the road I’m thinking about fenders, lighting, a front rack – part of me says that I should just save my pennies for a Velo-Orange frame (or something similar) and build up a baguette hauler around it. We’ll see. First order of business is to re-integrate ‘just hopping on the bike’ into my life.
Update – the saddle and pedal switch happened this morning, before a second shakedown run (pics from which will be posted later today).

Tereshkova & Lucid
“Valentina Tereshkova orbited the Earth 48 times during her three day spaceflight in Vostok 6 in 1963. First woman in space! .”
“Born in Shanghai to missionary parents, Shannon Lucid became the eighth woman in space when she flew aboard the Shuttle Discovery mission STS-51-G in 1985. Shannon made four more spaceflights including the 1989 Atlantis mission to launch the Galileo probe to Jupiter, and a stay aboard the Russian Mir station saw her break the record for the longest time spent in orbit by a woman. 188 days in space!”

Venus orbiter to fly close to super-rotating wind
The Venus Climate Orbiter, called AKATSUKI, aims to find out why blistering winds zip around the planet at speeds of up to 400 kilometres per hour. The upper clouds can circle the planet in four days or even less, and no one knows why. The effect is called “super-rotation”, because the bulk of the atmosphere is rotating much faster than the planet itself. Venus takes 243 Earth days to make one rotation.
