whatevs. i've only been passed once. dude on a carbon bike with some huge cluster of shiny sprockets on his rear wheel. i usually dominate all terrain at all times. i forget how fast i am.
naawww....my flats avg is anywhere from 20 - 30 on an old Cdale. i've got an 11t-28t freewheel that crushes descents at like 50mph, which is scary fun. seriously. 50mph. and i'm fat, too.
you're fast. just have fun.
