Congrats on the new bike! I got my 2100 in May- just love it! I made a few tweaks to it - I agree with the most comfortable ride possible! This forum is a wealth of information and i read and re-read all the advice and product reviews. I put some chromoly Speedplay Zero pedals on my bike - love the double-sides and the float option, a Terry Butterfly seat (the cut-out is ab/fab) and like you, my thumb pads were aching and I put on some Fizik (spelling?) gel bar wrap and that has really helped (in conjunction with good gloves). I agree with the feeling you described - I too feel so free and empowered out there, just riding and loving life. Enjoy your bike!
