I have an 06 Hardrock Sport and like it alot. Since I was going to be riding mostly around town I had the tires switched at no extra cost to Specialized Crossroads tires, fairly smooth on the tops but treads on the sides for some trail riding too. Also had thorn resistant tubes plus thorn resistant strips put on for an extra 25. If you're going to be riding just on roads or bikepaths Specialized Fatboy tires would be even faster, or Specialized Nimbus would be in between them and the crossroads I got since they have some tread. For what it's worth I got a black one but I saw some orange ones which look really cool. For the price you could almost get both and have one outfitted for street use with the fatboy tires and the other for offroad. ...I said almost; I wasn't even thinking of that!
