Take a grand from the wedding fund and tell her that a wedding lasts a day but a good bike just keeps on keepin on. and be ready to come back with something like- your not in it for the party your in it(the marriage) for her(which should be true).
The Novara Element is similar to the Randonee in its goal and the same price but made of aluminium. If your a member($15 lifetime) you get 10% off.

Or you could buy a hot used 2-4year old racin' bike and resell it after your done racing (Cannondale seems to hold their value quite well), then buy an all around bike.
