Besides that 15 tooth limit on double front derailleurs gets broken all the time whenever a compact crank is installed...no problems either.

Thanks for the Help. Heres the Pics. After my first ride--It's fast and wants to climb-Didn't use granny
Might be that this bike is peppy enough that I could have gone a double. I have a century next week, we will see. The best thing so far is the soft ride of the carbon vs my old Aluminum.
