Took it back for the 200 mile checkup and the LBS tells me it"s the nature of the beast. Adjusted out to the max and shouldn't drop the chain anymore but the rub is "normal" for that setup. I have a 20 year old Shimano that is whisper quiet and never dropped the chain or rubs against the FD. Granted it has adjustments that can move it if it did.

I just don't think Cannondale would sell a setup that rubbed "normally"
Anyone else experience this?
