What's your favourite gear ratio?

Like I said, it's very individual, and needless to say I would never recommend a gear you can't push. I withstand that a gear ratio around 2.75 - 3.0 will suit most people for most type of rides.

If I were being pedantic, I'd say 2.5 - 2.75.

An ~80" gear shouldn't be given such a generalist stamp of approval really.
