Have a Dew Deluxe,owned a Sirrus Sport Disc. Didn't like the Sirrus. The ride wasn't nearly as smooth as the Dew,and the bigger gears didn't match well with my hilly commute.

Stockholm:which Dew model? If it's the Deluxe or Dr.,I'd vote Kona all the way. In an urban environment,you need to stay close to your brakes,so the Trek's advantage of more handlebar positions is mooted. The lower gearing on the Dews handle hills better. The wider tires will soak up bumps better and do better off the pavement. The disc brakes last longer,won't wear on your rims,and will work better in rain/snow. Axiom makes a disc-compatable rack that will work,and I've seen a Deluxe with a set of full Freddy Fenders mounted(he did have to bend the left struts for clearance).
