Already 14.5mph average? That's awesome? I'm at about 12.5 and I've been riding for years. I like to say it's because it's a mt. bike and I'd go way faster if I had a road bike :-)

I agree w/the post above...Just keep riding until your comfortable. I like to ride for fun and "mental release" w/long rides. (50-100 miles)...The book that Carmicheal wrote (Lance's coach) is good if you want some goals and ideas on how to improve your riding.

You'll get better w/the clicking in and out as you ride more. And yes, please remember to spin, not try to crank out hard gears. I did that for years and killed my knees!

Good luck
