Hmmm - Let's see:

Hers:
Bike Friday Pocket Crusoe
Cannondale R600 ("Blueberry")
Surly Crosscheck
Trek 520
Lynskey Procross w/Custom Blacksheep Fork
Old Rockhopper (should sell)

His:
Trek 730 Multitrack (commuter, completely changed from stock)
Trek 2000 (trainer bike - headset trashed from sweat)
Bike Friday Pocket Crusoe
Lynskey Procross w/Custom Blacksheep Fork

I am sort of thinking of trading both the 520 and the cross check for a Straggler - yet to be determined. I also really want a Brompton to help out with my commute. Sigh. Always N+1
