>>1366000>Can you imagine what gear ratio numbers look like to them?I'm having some difficulty here,
like how competent people underestimate their own ability,
and with them self as a point of reference overestimate the ability of others,
they just dont understand how it's possible to be that stupid.
but condensing complex or arcane knowledge into an easily form communicable is an art in of itself,
mostly its to summerise a set of data into general principles using the simplest and most non specific language possible
short gears for low speeds and strong acceleration
tall gears for high speeds and sustained speed
>grug make big gear go fastbut the final gear ratio its self is affected by five parts of the system
>tire circumferencefor a 23-622 ETRTO tire
23*2=46 mm
+622=668 mm
*3.14=2097 mm circumference
>crank length170 mm x2 is 340 mm diameter
*3.14 is 1067 mm circumference
>chain ring sizeis chain pitch x the number of teeth
.eg 12.7x52=660.4 mm circumference
divided by 3.14 is 210.31 mm diameter
>ratio between crank length and chain ringin the above case the diameter of the cranks rotation (taking into account pedal position) is 140 mm more than that of the chain ring*
>ratio between front chain ring and rear coggears low to tall
26 28 is 1 to 0.92
36 20 is 1 to 1.80
48 14 is 1 to 3.42
52 12 is 1 to 4.33
