Gear Ratios

[Over50Newbie]

Hi,

Can someone help me figure out how to find out the gear ratios on my bike?

I have a 2005 Terry Classic - it is the one with the smaller wheel on the front.

I have 3 chainrings on the front and 9 cogs on the back.

Do I really have to count the teeth on each one to figure it out?

And do I have to measure the size of my back wheel?

Aren't there charts that are already done from the manufacturer that will tell me this?

I looked in my manual and it wasn't there, and I searched online at the Terry site, but I also couldn't find it there.

I am confused.

Basically, I just want to know which gear is lower compared to another gear. For example, when I'm in my 2 in front, 1 in back gear, it feels easier to climb a hill than when I'm in my 1 in front, 3 in back gear. But that could also just be my imagination.

Am I making any sense at all?

Any help at all would be greatly appreciated.

Thanks,

Lynette
