    The 12 speed will shift a 34 while the 11 speed is only set for a 32. I've been wondering if the 12 speed pull ratio is the same as the 11 speed levers so that you can get the 34 tooth on an 11 speed.

    I do have an alternative - I have the mediummk arm 11 speed and an a rear s=derailleur connector extender. This would allow an 11-34 cleance with all record 11 speed parts that I have.

    I was thinking that IF I could sell off the extra frames I have and the Specialized Allez, I would have room to get either a Look or Time frame. Preferably the Time made in France frmes with spectrum matrix that won't break.

    Campagnolo rear derailleur design is different between 11
    and 12 models. (aside from cable travel per click)

    There are some aftermarket derailleur attachments which
    lower the derailleur mount and that may work for this. Often
    sacrifices response in the high gears, but acceptably so for
    riders looking mostly for lower gearing.

    Thanks for that information. I thought I remembered the pull ratio being different - the 11 and 12 gear reals are different.
