i'm like eggplant.

i have uphills and downhills also tons of starting and stopping. full urban/city commando part with rushour gridlock downtown traffic in boston. and a full speedo flat paved bikepath part of my commute. that part i typically stay in one gear for miles and miles. i also ride around 5 miles of dirt trails on my commute. and i'm flipping through the gears the whole time.
