I phoned Calfee, and they said they'd call me back, . . . but since that hasn't happened yet, does anyone here know the correct front derailluer clamp diameter for a Calfee Tetra Pro?
I've just purchased a used Tetra Pro frameset, and there is what looks like a spacer (black plastic) around the seat tube where the front derailluer would be attached. Is this to protect the carbon frame from damage due to the clamping action of the front derailluer, or can it (safely) be left off?
All help will be appreciated!
