New bike...can't shift into big chainring!

[OakLeaf]

Maybe you know someone who has R700s on their bike already, or maybe one of your LBSs has a bike you can test ride, just to see how the shifters work for you.

But if you can reach the brakes as is, a couple of people on here have said that the spring tension on a Dura-Ace front derailleur is much lighter than 105 or Ultegra. That would be a much less expensive change than swapping the shifters (plus you wouldn't have to re-tape the handlebars, which is ALWAYS a plus in my book. )
