|Dura Ace front derailleur help||ridemytrek|

|I am building up an old Trek 2100 (the one with the carbon main triangle and aluminum stays) with Dura Ace. My problem is the front derailleur, which calls for a clamp on. The derailleur I have is a 31.8. Is this the largest Shimano makes? I measured the diameter of the tube at 1.36". Can I make this derailleur work?
