I forgot to mention, in addition to the buzzkill handlebars, the 2.1 has carbon forks, seat stays and seat post. I was hoping it would smooth out the ride and it does. I test road the 1.2 to see if the 50 cm frame fit me and it did. I then decided to try and reduce vibration as much as possible by going to the 2.1.

I didn't want to not ride my bicycle because I was uncomfortable (OK - just call me a wimp). The great news is that I am really enjoying riding this bicycle.

Have fun shopping.
