I test rode the System Six a few months ago (as part of the agonizing process of purchasing a new racing bike!). I LOVED it. It climbs like a dream!

I had only a few minor issues with it, one problem was it's weight. I'm looking for a real change from my 22 pound beast, and the System weighed in at 19 pounds (not bad, but a horse when compared to the 16 pound Cervelo I rode!). And, I'm trying to get away from an aluminum bottom bracket, which it has (the system six has an aluminum back triangle and bottom bracket with carbon in the front)...looking for something a little "snappier." Criticism noted, I again say that I really liked this bike! I think that if you're getting a good deal and you like it...GO FOR IT! You can't go wrong with it, honestly! It's a GREAT racing bike.
