  • Spoke replacement with a disc wheel

    I rigged up the Gravel Roadster with a 9-speed cluster, a Suntour Cyclone derailleur, and a 7-speed bar-end shifter. So gears. I put gears on the old Big Apple one-speed.

    I’m setting it up for my brother, who’s moving out here in August, after 20 years in the Navy. He ought to have a bike to ride, and I’m doing the shakedown cruise by riding it with roadies on the lunchtime ride at work.

    One of them noticed my rear wheel was out of true, and when I went to fix it (after not finding my truing stand anywhere), I saw that a spoke was broken. There are a few silver spokes mixed in with the black already, so the wheel probably took some damage at one point, and other spokes may fail.

    The downside of the disc brake, is that you can’t really get a new spoke in there without pulling the rotor. I poked at it, then just pulled out the DeWalt and the Torx bit and started dismantling.

    disc-whee-2lThe new spoke went in easily, and I thumbed it down to into the hub flange to angle it correctly, and peeled up the rim tape to drop in the new nipple.

    A few turns with the spoke wrench (and a little slipping and rounding – what’s up with that?), and the wheel is now acceptably true. I failed to mount the tire in the “correct” direction again, though.

    Check the hitch connection on that homebrew bike trailer. It seems like it deserves more study. I think there’s a fork or two in there, creating a universal joint…

  • I can’t be the only person to recycle cable ends

    I squeeze them transversely (if the hole was a rice grain, I’d grab it by the ends and gently squeeze until it turned into a lentil), to open up the tube, then I clean up the opening with a scratch awl or corkscrew end. Or a nail. Pretty much the closest thing that might work. There’s a kind of fit curve between “can I see it from here,” and “I’ll know it when I see it.”

    If the cable goes into the cap, I’ll crimp it down with the needlenose pliers. Bike shops have a special tool for it, I think, that puts a nice crease in the cap instead of mashing it willy-nilly and hoping for the best.

  • It’s a corker

    I like to use corks as bar plugs. They’re light, they’re natural, they’re free, and some of them have a personal connection. This one is from a bottle of Van Duzer I drank with my friends in Oregon when one of them was a winemaker there. I cut the corks in half, one half in each end of the bar.

    The only trouble is… how to get them out? Plastic plugs pry right out, and Velox plugs have an expanding screw you undo.

    For cork extraction… use a corkscrew! I’m pretty sure everyone does this, but it’s amusing and enjoyable to me every time.

    The new tape (Bike Peddler has cloth tape, but you have to ask, and it’s only black) gets folded over to tuck inside, with the cork holding it cleanly.

    I did some other stuff to the Gravel Roadster at the same time. And shellacked the tape! I never do that, but I bought shellac to finish some paintings, and figured “what the heck.”

  • The Peddaling Baker

    I bought some baked goods from this fellow. He mills his own flour for his sourdough loaves, and sweetens his peanut butter cups with xylitol.

    The downside is that two peanut butter cups and a hamburger bun-sized “loaf” will set you back $10. The bread was really good, and I ate it in tiny slices to maximize the payback, and kind of approach it as a $3.50 box of melba toasts, not a loaf of bread you could put in a shirt pocket. The peanut butter cups were grainy, so maybe he could mill his nuts a little finer.

    I support what he’s doing, but I can’t really afford to support what he’s doing.

  • 47mm Marathon Supremes on a Quickbeam

    47mm Marathon Supreme measures 43mm

    Here’s a 47mm Schwalbe Marathon Supreme measuring 43mm actual width on a wide-ish rim.

    Yes, those are my calipers.

    I like the Marathon Supreme on the front. Cushy, and fast. I put in my best commute time after installing it. Not scientific, but it’s a nice-feeling tire.

    I took the Marathon Supreme off the back, due to clearance issues, but I may try again with a 19mm rim. The Kwest I have on there now looks anemic next to the giant Supreme on the front. I also plan to go back to the S3X, in order to ride some climbing loops at lunchtime.

  • STOLEN BIKE – Valiensi

    One of James Valiensi’s bikes was stolen today at CSU Northridge. Yes, that’s his name on the down tube.
    If you see it on Craigslist or around Northridge, please email him (through Flickr?), or let me know and I’ll pass the lead on to him.

    Dang, what a loss.

    Die the leather yourself. And the cork to match. Brilliant advice from Mr. Matchak.

    I painted this little watercolor last night instead of riding my bike. It’s about 4″ across, on gessoed panel.

  • ** Stolen Bike ** New Dove bars



    ** Stolen Bike ** Dove bars, originally uploaded by BikeTinker.


    This bike was stolen out of my back yard near the end of last week March 4 or 5, near downtown Santa Rosa CA.

    Luckily, they left much nicer bikes behind, but unluckily, this is a friend’s bike!

    I’d JUST finished the new bar setup for her, with new shifters (courtesy of super nice internet friends), new Dove bars from the Rivendell Garage Sale, and new cables bought at retail from the Bike Peddler.

    Bleah.

    Santa Rosa makes it super-easy to file a report online, and I encouraged my neighbor to report the bike he’d had stolen the week before.

  • Commuter Time Trial Bike

    Commuter Time Trial Bike

    Aero bike, fenders, fattish tires and luggage.

    I did my 36 mile commute a couple times last week, and found myself wondering why longer commutes aren’t run with fendered Time Trial bikes. This is my take on a stock TT bike, with fat 650B tires, fenders, and luggage (a Revelate-style seat bag and custom front trunk). Oh yeah, it also has lights, a fixed gear and a chain guard.

  • Quick release basket

    Total genius! A tongue on the front of the basket slips under the front of the rack, and… A snapping toolbox latch attached to the rear of the basket hooks onto the back of the rack.

    Snap the latch down, and the basket is firmly attached to the rack. The tongue in the front provides the tension in the system, since it doesn’t let the basket sit flat by itself. You have to use the latch to pull everything tight.
