I went low budget. Shimano Ultegra. The bike was fitted and purchased from Signature Cycles, whose NYC fitting studio is 4 blocks from my apt. Before I committed I spoke with a serious rider friend in FL, who said she has heard of them and one of the girls she rides with flew up to NY to get a bike from them. After staring at Sevens online catalog this afternoon I was tempted to upgrade to the Axiom frame, but my overblown budget couldn't take the extra $800. I've also decided to skip the paint so I can start riding it sooner.
