69 isn't that bad, but it's not as spinny as I was expecting and as he mentions it'll be used by the missus it's best to manage expectations a little.

i also found that seatpost height was very important as the standard was a touch too short at it's full extension for me and my thighs were screaming after 10 miles down cs7 when I wouldn't break a sweat along there typically.
