    useless post of the day...

    this morning on my way home from work, i noticed one of those portable police speedometers halfway up one of the hills i normally walk up. my legs were still fresh so i said why not... i managed to hit 24mph with a 42-16 ratio and 170mm cranks before i ran out of gear. the hill is about a 20 degree grade. i have no idea if this is good or bad, but i know i will be stepping up to a 46t when i get the money...

    get a rear cog, not a chainring. cogs are cheaper and have more effect on gear inch than chain rings.

    1 tooth on a cog is about 3-4t on the chainring effect! They are also cheaper and have less effect on the chain. Add a new chainring and you probably need a new chain, unless you have spare links.

    Also, post in the new spinning thread for listing your high speed tales.

    24 MPH on a 20 degree road grade on a bike? Um, no. Hell no actually. Downhill that would be an impossible speed to maintain over any distance. The bike would get away from you and demand more. Keeping it at only 24 mph (say as opposed to keeping it a 5 mph) would be a herculean task. You ain't Hercules. Uphill? Yea, then you wake up. I think your sense of grade is off. Way, way off.

    i thought the grade might be wrong... it was a rough guestimation...

    Oh, I mean unassisted. For example, on the downhill a brake could be the equalizer. On the uphill - remain in the dream as long as you can.

    dbgray21,

    Yea, I know. Just giving you a hard way to go. Try bettering your speed on that hill each week. Hit that hill for all you are worth whenever you need to use it in your daily life but only "test" yourself on Friday's or whatever. You'll be surprised at the results.

    so 42-16 uphill? You'd have to hit ~120 rpm with your legs to do that... and if you are even close to your estimate of a 20 degree hill (what does that equate to a ~%30 grade?) and the distance was of any consequence, I find it hard to believe you hit 24.

    And why would there be a mobile speed trap on the uphill?

    If my math is correct, a 20 degree hill equates to a 36% grade... that is a hella steep hill.

    He said he was halfway up the hill when he decided to ride back down and get a speed reading. If the hill is short enough, and with a 20deg%. grade it better be, 20mph is not unreasonable.

    It would have to be a very short ride at that grade, though. I've gone over 30mph on my bike on a hill that's only a block long and I don't think it's over 10%. (42-15 gearing. I spin out at >140, according the the cadence meter on my roadie)

    I think 1 tooth on your cog equals out to two teeth on the chainring.

    Ingredients

    2 1/2 cups wide egg noodles
    1 teaspoon vegetable oil
    12 cups chicken broth
    1 1/2 tablespoons salt
    1 teaspoon poultry seasoning
    1 cup chopped celery
    1 cup chopped onion
    1/3 cup cornstarch
    1/4 cup water
    3 cups diced, cooked chicken meat
    Directions

    Bring a large pot of lightly salted water to a boil. Add egg noodles and oil, and boil for 8 minutes, or until tender. Drain, and rinse under cool running water.
    In a large saucepan or Dutch oven, combine broth, salt, and poultry seasoning. Bring to a boil. Stir in celery and onion. Reduce heat, cover, and simmer 15 minutes.
    In a small bowl, mix cornstarch and water together until cornstarch is completely dissolved. Gradually add to soup, stirring constantly. Stir in noodles and chicken, and heat through.
