    The fix is in!

    Just finished my Schwinn World Sport thrift shop fixie conversion. Haven't even ridden it yet. Going to take it on a shakedown cruise around the neighborhood, then try 10 mi. or so on a MUP.

    Used the original hub with red Loctite, lotsa torque and a BB lockring (sometimes called a "suicide hub" in the fixed gear forum). Got a NOS stem on eBay because the one with the bike was the wrong quill diameter (undersized) and too short a reach. New Vittoria Zaffiro tires from Nashbar. Anything chrome or aluminum got polished with Simichrome. Sold removed components on eBay. Trued the wheels on the bike; they were in pretty good shape. For now I'm just swapping the pedals from my road bike when I want to ride it.

    Gearing: 40/15

    Sheldon Brown's site was invaluable, of course. Got the sprocket and chainring spacers from Harris.

    If I take to riding fixed I might strip and repaint the frame next year, and get a "real" fixed gear hub.







    Now to see if anything falls off...

    Ride report

    First, for BubbaDog: Did not! Nyah, nyah, nyah! Might have been a different story if I'd tried a trackstand, tho.

    Well, it's different, that's for sure. And I like it. After a non-eventful neighborhood shakedown I took it on a flat MUP for about 10 miles. The path has some mild grades, with the biggest "hill" being a pedestrian overpass. I chose the 40/15 gearing to approximate my "fast" cruising gear on my road bike.

    You definately feel it in the quads and, to a lesser degree, the knees. My knees are healthy so far -- knock wood. After being sharply reminded a few times that I cannot coast (I have a habit of standing and stretching my legs--whoops!) it was less of an adjustment than I'd feared. OTOH, I quickly got the hang of slightly "unweighting" over bumps.

    The most interesting thing is that once you get to a nice cruising speed and cadence on a flat a sort of feedback mechanism actually assists you with pedaling. The momentum of the bike helps to push your legs thru the stroke.

    On a slight upgrade, a bit more attention to pedaling in circles (i.e., pulling up on the pedals) is sufficient. Standing and mashing on the few "steeper" upgrades was kind of fun.

    There wasn't a steep or long enough downhill to really get me spinning.

    I was breathing harder and my legs felt a bit more tired than a comparable ride on my roadie, but that's the idea, no? Too bad the season is winding down. But hey, I can put it on the trainer...

    I do need to adjust the position of my brake lever. It's too low and a bit of a reach for the brake lever. I'm only using the front brake after reading Sheldon Brown's article on braking. And I need better brakepads -- maybe the salmon Koolstops.

    You will defintely be reminded of that once you get back on your geared bike after you've been riding fixed for a while. You'll encounter 'dead spots' through your pedalling stroke.....but your legs will quickly relearn to pedal through those spots.

    Nice conversion, BTW.

    But...it's so C-C-C-C-COLD! Seriously, I tried winter biking and didn't like it.

    Welcome! You are now one of us.
    I thought I was suffering from depression once. Turned out, I was simply surrounded by idiots.
