I’m not quite certain what (or if) I was thinking yesterday.

The bike docs at Two Wheel Drive had rung me up Tuesday afternoon to say my 1995 DBR Axis TT was out of headset surgery and doing nicely, but I couldn’t get down there to collect it before closing time.

TWD doesn’t open until 10 a.m., so I thought I’d go for a 45-minute trail run Wednesday morning before motoring down to fetch the bike. Sweat a little rather than a lot, don’t you know.

These things I did, then had a medium-heavy bite of lunch.

Sensible so far, yeah?

Don’t worry. It never lasts.

Weather conditions be damned, I just can’t not ride a new/recently repaired bike.

So I kitted up and rolled out to the Elena Gallegos for a short shakedown cruise that wound up being about 90 minutes.

It was toasty out there — just shy of 90 degrees — but bearable. And anyway, I barely noticed because I was having so much fun riding this 28-year-old mountain bike.

Don’t tell The Industry, but you can still mine a few giggles from a made-in-USA titanium MTB with a Tange steel fork, triple crank, eight-speed XT, V-brakes, flat bar, Grip Shift twisties, 26-inch wheels with 2.0 rubber, and a creaky old 1954 MeatSack® motor that couldn’t pass an emissions check in Mexico City no matter how much mordida you paid.

It’s frisky and maneuverable and weighs just under 24 pounds with a saddlebag holding two spare tubes, tire irons, and a minitool. The flat bar, V-brakes and plumpish tires let me roll over a few items I have to dodge on a drop-bar ’cross bike with cantis and 32mm knobbies. And the smaller wheels put me a little closer to the ground for purposes of falling off onto sharp rocks and spiky foliage.

I managed to keep the greasy side down yesterday through an abundance of caution and the avoidance of all truly technical sections, though I sampled a few rocky bits in the name of Science.

Mostly I was just noodling along, enjoying my little trip down Memory Lane, recalling the Good Old Days® when a rigid 26-incher with an eight-speed triple and 2.0 tires was as good as it got.

• Editor’s note: “Shakedown Street” is, of course, a tune and an album by the Grateful Dead, produced by Lowell “Little Feat” George. My favorite underground cartoonist — Gilbert Shelton (“Wonder Wart-Hog,” “The Fabulous Furry Freak Brothers”) — did the album cover art.  Last, but not least, a resounding “Damn The Man!” goes out to the Save the Elena Gallegos rebels, who gave a righteous beatdown to an ill-considered plan to install an unnecessary and unwanted “visitors center” — the thin edge of a development wedge — in our little piece of paradise. Don’t tell me this town ain’t got no heart.
