More Tinkering

After getting the Quickbeam’s S3X squared away, I mounted giant-sized 47mm Schwalbe Marathons, but the front couldn’t quite clear the fender.

  • Remove extra large Marathon tire, install Kenda Kwest in 37mm. Looks pretty good!
  • Pinch the tube under the tire bead, and have it blow 20 minutes later sitting in the entryway. 6″ blowout in a never-patched tube.
  • Put in a new tube. Lots of patches on it, so it’s got to be good.
  • As long as the wheel’s off anyway, clean the rim, hub and spokes.
  • Putting the wheel back in is a little fussy, because the allen bolt on the front fender stay pokes way in and makes it hard to get to the spades for the dynamo wires to attach. The rear stay is even worse. It almost touches the cog, and looks stupid.
  • Change out all the stay mount nuts for shorter ones that don’t crowd the hub or the dynamo wire tabs. Make sure they all take full-size hex heads.
  • As long as the nuts are out, I should reorient the V-O fender stay mounts that don’t quite “stay.” They’d been pointing up to get more of the stay inside the mount, but that didn’t help the grip anyway, they may as well hang down properly.
  • Hey, look, the front brake pads could use some sanding…
  • Snip the S3X shifter wire shorter. That’ll look better. Boom! Crazy hair! Wire strands splay out everywhere. Dammit.
  • Remove left crank and bottom bracket cup. Something down there’s been creaking. Grease up the cup threads, and inside, where it contacts the bearing. Reassemble. It only took a minute, and I think it worked.
  • The rest of the bike is really starting to look fresh, and the tape is really skanky. I think I bought a roll of green Newbaum’s from Rivendell when I got the orange and blue for the Bontrager and the red and black for the Gary Fisher.
  • Peel off top layer of tape. Wow. That looks positively Victorian under there, like something a coal miner would wear. Cover it up, quick… with a single roll of tape for both sides.
  • That’s pretty half-wrapped; it barely comes past the hoods. Make up the difference with the tail-end of a black roll, and be done.
  • Go ride with the dog.
  • Suspect that the new oft-patched tube has a slow leak.
  • Ride to the store for 6 lbs of sugar, 6 pack, two sodas and a half liter of red wine vinegar in the front basket.
  • Find that the fender front fender is loose. The load is a littel wiggly, and something rattles when you whack the basket. Pop the wheel out, tighten the bolt that mounts into the rack, and get the wheel back on in seconds. All the practice has paid off!
  • Buy a fresh tube (SEVEN DOLLARS??) and remount the tire. Do all the stuff as before, but with fingers crossed.

finally got this thing dialed in!


After taking the dog for a long ride with the mountain bike (note to self: spend more time maintaining bikes than tinkering with them this winter), I got into the final adjustments on the S3X.

  • Adjust the cones.
  • Throw away the aluminum washer and replace it with one of the old thick anti-rotation (tabbed) washers. Looks pretty slick. The aluminum washer had already smashed into the thin steel washer, and was locking up on the axle threads. I don’t think I can get the aluminum washer off the steel, since it’s kind of grown around it.
  • True up the wheel. Easy peasy. I’m still doing the Jobst “only quarter turns” thing, but I still don’t like it. It makes it easier to grab the nipple, but I don’t feel you can get the wheel as true as using 7/8 turns and 19/32 turns.
  • Mount the new Schwalbe Marathon 47-622s I just got. Yeah, yeah, they shouldn’t fit on the Quickbeam with metal fenders, and they rub on the brake bridge mounting bolt, so…
  • Pull the rear fender and clean up the mounting. Replace the brake bridge hanger with a rivet! Rivets are low profile, and leave enough room for the hanger bolt. Also cut a new leather washer for under the mount, and file the mounting slot longer, to get the fender a micron higher. Replaced the cork chainstay bridge mount with an old bearing. Looks cool. These fenders need a respray, but I’m out of the Quickbeam-matching spray paint.
  • Mount the fender and wheel and Yay! It fits pretty well. That top fender mount nut had been a killer, even on smaller tires. Feel so good about the rear, I mount the front Marathon as well.
  • Whoops. Appears to rub on the nut mounting the fender to the Nitto rack. There may be a way around this, but I doubt it. The clearances are minuscule. I’m putting a different tire on tomorrow.
