    Id bring a rag. Id also bring a new chain and two quick links, and id bring the extra links i cut off when i sized it.

    The chain goes on the bike. The links go in with the patch kit.

    The rag is...

    don't shorten your chain

    Because there's no reason to. If you ever go back to the wide cassette, you'd just have to lengthen it again.

    As long as the chain length is within the rd's wrap capacity, run it as lengthy as you...
  3. Welsh, it won't let me quote you...

    Hope i didn't come across wrong. Long day, and text is a cold medium, anyhow.

    I like your 336 number. Ill have to use it more.

    easier than .00297

  5. not quite right regarding development

    But close.

    Gear inches refers to the wheel diameter you would have if you were riding a penny farthing.

    Development...distance traveled, is gear inches times pi.

    assume a 700x25tire...

    What is interesting? If you wish to damn somebody, both barrels is the way to go.

    I have no vested interest, yet i wait. I hope i read you wrong. Really.

    much love.

    I also super-dee-duper soft pedal on front downshifts.

    Seems to help.

    I do like the pins, though, for up-shifting.

    In your photo, it looks like a pin grabbed it, and then let it go just in time for the chainstay to grab it.
  9. pins

    My bike. 52/42/26 campy 9 speed crank.

    13-28 7 speed freewheel.

    Shifting from the middle ring to the small ring, if the chain is in the middle of the freewheel, it often hangs up on the chain...

    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.

    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...
  23. 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...
  24. 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...
