Hello, newbie introducing myself with a really inane question.
It's been a while since I rode a bike regularly. I used to have a road racer in my teens which had 5 gears. That was fairly simple to understand in terms of which way to switch gears to go faster or uphill. Now I find myself some ahem! years later having to commute to work by bike. It's got 21 gears which I'm finding difficult to understand.
for example: If I'm in pedal gear (large cog) 2 and I've gone up through the small cogs from 4 to 7, where am I supposed to go next? 3:1? 3:7
What exactly is the order of the gears supposed to be for smooth transitions. I tend to stay in 2 and move from 4 to 7 on my commute depending on the slight inclines. On the way home I can speed along in 3:7 when I get a bit of flat to slight downhill.
Apologies if my terminology is all wrong. I understand the basic concept that large cog to smallest cog will be the fastest but without counting all the teeth and working out the exact values when multiplied I find it hard to see why you would need 21 gears.
