I am new to this forum was wondering if anyone has tried to XR1? just got mine about 3 weeks ago; got the Di2 Shifting (which I love) I got better wheels to go with it: Shimano RS 81's....I am just not certain how I feel about it. Other people that got new Bianchis and bikes say they LOVE their bike. I LOVED my previous bike (Cervelo R3) but was a little big for me. I feel this one may 'fit' me better, but I guess I thought I would love it off the bat, feel like its lighter than anything and fly up the hills. I just don't feel it and it was a lot of $$.
