Yay from here as well! Elk- you have turned your life around!

Yeah, just ride for a few weeks to let your muscles start adapting. If you are not in pain don't worry about tweaking your bike for a while. The longer you ride the more obvious it will become as to what changes you might need to make. People tend to tweak their new bikes back and forth so frequently at first that they totally forget how the bike was set up to begin with, or which tweaks resulted in what differences for them.

Isn't it wonderful to have found a healthy exercise that seems like FUN rather than work? That's how I feel about it!
I lost 15 pounds too over the past 2 years of walking and biking....after a lifetime of non-exercise/non-sports.

You selected some really great wool pieces to get set up with. You'll get a LOT of mileage from those items you chose.

Wearing my snuggly wool tights and skyline zip top right now......
