SO, I changed my order from teh Colnago Extreme Power (too long of a wait) to the BMC Promachine....available now in my size for $500 less. I ordered a Braze on F. Derailleur for the Extreme Power, but need to get a clamp on for the BMC....so i need to change my order...and quickly. Can anyone tell me what size clamp i need to get? Thank you so much guys!
