If there is a little more in the budget, and you would prefer American made, give Lynskey a call and talk about what they have to offer. Sometimes there are deals to be found that aren't published!
Now granted, I paid more for my Lynskey with 105/FSA mix than the "full" Ultegra MB, it wasn't "that" much more, and I absolutely love the way it rides. Customer service was amazing, too. Not in any way dis'ing the MB. Just throwing out another option to consider.
