    Yep, a steel ruler. Or the ruler on my leatherman. My ruler is the park tool one with the soke guage holes and what all. The ends are rounded, i.e. it's a foot plus some. hence the plumb bob, which...

    Goodness! I feel silly. Never held one of those in my hands before. :)

    Thanks, FB. Now, i'll have to educate myself. That'll take awhile, but you opened a door. I appreciate that.

    As to bike handling, I couldn't agree more. I'm pretty good with it, indeed, surprising...

    I was afraid of that. What does that upper screw do?

    Smaller wheels would open up all kinds of possibilities.

    Thanks, Leebo. 700x25's, most likely. The 1x11 is out, because i have no money. Not that much, anyway.

    I've got a few options. One would be to find an old 94/58 bcd mountain crank and run...

    Can you adjust the upper or lower spring?

    Is there an adjustment screw down on the cage?

    I googled pictures, and it looks like there is. Don't know for certain it was your derailleur, though....

    Thanks. It's really cool that you've got your kids riding.

    I appreciate all your input. It actually backs up my reasoning, but i understand your perspective, too.

    My cyclecomputer cuts off at...
  9. I agree. Thanks for your insight.

    I agree. Thanks for your insight.

    So, after giving this some thought, and running some rough calculations, with a 14 inch gear, my absolute peak input torque at the rear wheel would be right at 200 foot pounds.

    With a 53-11 gear,...

    That's good to know. What sorts of grades do you encounter on the unpaved roads? How much bike and gear weight are you dealing with? What's your slowest seated cadence?

    Just out of curiosity?

    Well, no, it's not. :) That's why i posed the question.

    Thanks. That's good to know. I've spent the evening reading about torque as it applies to chain-driven power transmissions. I regret my lack of formal education...but, when and if I get my head...
  14. I think I I follow you. You are saying that,...

    I think I I follow you. You are saying that, given the same power output, using a lower gear does not increase input torque at the hub?

    Edit: Damn, I had to think about it. Now, I follow you a...
  15. Potential mechanical problems with super, super low gears.

    I'm not referring to balancing a bicycle.

    Can using a low gear create enough torque at the hub to cause hub failure(stripped hub threads, shattered freewheel or freehub pawls, broken spokes or...

    heard that. It's impossible to figure for any and every possible failure, anyway. I do see co2 as a glaring weak link, though. That's just me. With a pump and patch kit, you"re good for a whole lotta...

    When away at college, I left my ratty old pancake compressor slung in the back of my truck. I'd plug in on the outside outlet at Subway to top off my tires. Never had change for the gas station down...

    And it's good for the trees. That's what they breathe. Maybe we should do more replanting. We actually do replant more than we used to. Whole nother subject.

    I guess I'm the somebody. I got a pump, patch kit, a tube, and usually a spare tire, too. And good tire levers.

    I've also got enough stuff to fix a chain, at least temporarily, pull a freewheel(i...

    Yeah, I thought of that, too, about the valve. Using a smaller tube makes sense.

    Perhaps the inner inner tube should have a prefab hole for valve stem of the outer inner tube.

    I don't know, but FB made me think back to my last flat. One nail caused two holes in the tube and more or less cut it to ribbons in the process. The tire had two holes. I taped up the tire casing...

    I'm from the South. We say the opposite of what we mean half the time, anyway, so I don't pay it no mind.

    Sorry I talk in circles. It's just that they all play on each other. If you have room for a longer chain, then the lower pulley should wear less.

    I wonder what your chain length looks like. I also wonder what sort of spring tension you've got going on in there. On some old models, it may be adjustable. New models, i don't know, though a man...
