Man, looking at the spec sheet and pic, it really doesn't seem a huge step up from the JTS...well, not now I've swapped out the stem, seatpost, seat, bars, ties, brakes and pedals on my JTS anyway. Nicer wheelset and fork I guess. Maybe if you could live with the JTS spec, then (like me) you could change out what didn't work for you and still save some bucks.
Not much help but it's all I gots
