Fenders/racks will go right on. The bridge on the suspension fork should have a threaded hole in it for mounting a fender;you'll prolly need to get a smaller screw at a hardware store than what the fenders will come with,but that's no big deal. Rear fender/rack will go straight on.

Used a Giant Sedona as a commuter for a year. Sold it because it was heavy and slow. If your commute is short,the Crossroads sould be fine. Might want to swap the suspension fork for a rigid,and put on some narrower/higher psi tires though.
