    Caution;  Merge;  Workers Ahead! Gear ratio

    Folks,

    I'm currently running a 32:20 gear ratio and was looking to make it a tad more difficult. Which would be the harder gearing.

    33:20 or 32:19?


    Thanks in advance.

    Scott forty G; Without getting into the calculators, a good "rule of thumb" is that if the front ring has more teeth than the rear cog, that making a change to the rear cog by one tooth will affect the gearing more than making a change to the front by one tooth. Therefore, the 32:19 will be a little bit taller gear.

    Not only is this guy totally right but it is also cheaper to buy cogs than chainrings.
    no chain no gain.

    And you're right too - I wasn't even thinking of the price factor.... Though if your front ring is worn, and your rear cog is in good shape, a 32:19 and a 34:20 are nearly identical.
