You'll need a 34.9mm bottom swing (high clamp band), top pull front derailleur - model FD-M771.

The FD-M77x series comes mainly as dual pull units (I've not seen any single pulls) and supplied with shims to fit smaller diameter seat tubes, so there is less of a chance you can mess up with your choice.

Btw, is the stated frame weight accurate?

I got the fram yesterday, weighs in at 1370 grams, a bit more than the description, but it looks really nice. can't wait to build it up.
