i love my fx 7.7 but it's not an all purpose bike - it's my weekend bike - i "fair weather" bike commute on a trek 800 - and place it in the company bike rack - which i am thankful for - but the carbon frame would not survive that rack or the abuse of other bikes placed on the rack.
i would go even lower than the 7.6 - i think will replace my trek 800 - prob next year with a Giant Escape 3 as my all purpose commuter/errand bicycle.
