How do you know if you "run out of gear"? Is that like you used ot be able to go 100 mph in "x" feet and now you can only go 100 in the a lot less distance but you get there quicker? Do you need a "taller" gear then (closer to 1:1)? What is the feeling of too much gear and how do you explain it? Please correct my terms if they are wrong. Thanks.
