Cruisin’ the streets

  • Spoke Wrenching

    I recently rebuilt the back wheel on my bike, which had been breaking the odd spoke and getting more & more out of true.

    Spoke wrenches are so tedious when one’s fingers don’t fit in between the spokes like they should. I figured, hey, if the pros can use power drivers, so can I…

    Dug a goobered #2 Philips bit out of the ziplock baggie labeled “NFG Bits” and applied it to the bench grinder. The strip of tape on one flat makes turn-counting easy enough that I can actually get it right. It’s not hardened, so it probably won’t last for more than a few wheels, but this is the first scratch-built wheel I’ve done in decades and that baggie is nowhere near empty.

    I read through Jobst Brandt’s The Bicycle Wheel to get prepped for the job, removed the old spokes, laced up the new ones, lubed the threads & rim washers, and the wheel trued up almost perfectly just by counting turns.

    Did the spoke aligning & stress-relieving tricks, applied some final tweaking, and it’s perfect!

  • Bicycle Performance

    Back in 2006 I biked to the Main Event Criterium in Po-town to watch real bicycle crazies in action. Despite the name, the course was literally around the blocks near the Poughkeepsie High & Middle Schools on Forbus St & College Ave: about 0.75 miles per lap.

    Now, most places, folks give ‘bent riders a smile and maybe chat ’em up. Not here. Talk about a cold shoulder: the local-resident bystanders were friendly, but the real riders and their main squeezes obviously regarded my pimped-out recumbent as a Hostile Gesture. Barely even a sideways look; it’s as if I didn’t exist.

    I timed a few laps of the Masters 40/50+ race: Olde Fartes like me, but still players. They did 15 laps (maybe a dozen miles) at 16-17 mph. Two guys duked it out for the lead all the way to the finish, with the rest of the pack half a lap behind and fading.

    In my ordinary rides I can cover a dozen or so miles at 15-16 mph, riding with vigor but not an all-out, my-eyeballs-will-explode effort. That’s on open roads with actual hills, traffic signals, and no pace car to clear the way.

    Obviously, I’m nowhere near their well-chiseled physical condition.

    There’s no comparing the bikes, either.

    They’re riding the latest carbon-fiber weight-weenie frames on exotic aero wheels with pitifully few spokes. One guy blew a tire with a bang that sounded like a gunshot.

    I’m riding a steel-frame Tour Easy recumbent bicycle with a fairing, fat Kevlar-belted tires, tire liners, steel spokes (and lots of ’em), a rack, two baggage packs, a water bladder, ham radio, blinky lights, spare batteries, a tool kit, and fenders. Not to mention an aerobelly. Heck, my tool kit probably weighs more than their frame.

    Imagine what they could do on real bikes…

    Somebody mentioned that the TdF guys hit 70+ mph on downhills. I forebore to mention that the human-powered speed record is nearly 80 mph on the flats… I figured that would definitely be regarded as a Hostile Gesture.

    [Update: a friend accused me of riding while carrying more smug than legally permitted, even for Prius drivers. Guilty as charged.

  • Christmas Day Ride

    Couldn’t pass it up: a family bike ride on Christmas Day in midstate New York!

    A mere 40 F and breezy, but no snow on the roads… a good time was had by all.

    Memo to self: fleece + bandanna is fine at 40 F.
