Hi Melissa & Over50Newbie!

Not a problem at all !! I find it very interesting reading how gears differ on different bikes with different size tires, etc.... (I'm like a sponge for learning new things -- though, retaining that information is anothing thing )

I am enjoying my bike A LOT (with the exception of my saddle..... much too "nosy" for me (in other words, very CROTCHY!!)......I will have to do my research on the most popular saddles for women & try a few of them out at my lbs) ).

Have a wonderful evening!

Denise
