So you've probably read about my Girlfriends F400...?
If not - it's nice - good gearing, well equipped etc. I personally don't like the ride position. It's aimed at the hybrid commuter set and as such has a very upright position for a shorter male (5'5"). I guess if you are taller the handlebar height is ok but for me at it's lowest point it's too high. One other thing I don't like - something to do with this height of the bars, the offset of the stem the rake of the forks and the relatively light front means the steering is very light (compared to my Raleigh Twenty) It's stable - the steering almost seems self-righting in fact - but on a climb I feel a little scared as the front wheel is close to doing a wheelie if you put some work into grabbing the bars for extra grunt...
