Understand bike gearing - intelligent overview for beginners

Posts: 312
Well, being a newbie I dont fully properly understand bike gearing and was a bit coy about confessing that on this forum in order to ask for advice. I read the input on other threads and think "Wha...?" So instead I've been trawling the web and found this on YouTube, seems an intelligent overview (but then it might be cr*p because I'm a newbie and am not much of a judge).
So for the benefit of other newbies similarly confused & shy, here's what I found:

I hope its not cr*p because it made sense to me.

You could also draw up a gear-inch spreadsheet based on the following formula:
Gear inches = (chain ring teeth/cassette cog teeth) x wheel diameter
So if I'm in the big ring and smallest cog of my cassette:
Gear inches = (50/11) x 27 = 123, which is a 'hard' number of inches to pedal.
Or the opposite combination:
Gear inches = (34/25) x 27 = 37, which is an 'easy' number of inches to pedal.
I'm running a compact by the way...

Try this instead, much easier.

Aye that's a nice little application, but it's always good to see where the numbers come from.
