OK, I got a new Specialized Rockhopper because of the great frame, excellent reputation, cool looks, relatively good components, & low price (leftover '05 for $400). Now here's my problem: I am an "easy rider"; i.e., I ride mostly paved or hardpacked dirt roads. The tires on the bike are (for me) overly agressive: Spec. Adreneline- they constantly throw sand & pebbles all over everything (including me!) when I'm riding on hardpacked county roads. I'm thinking about getting the LBS where I bought the bike to replace the tires while they're still almost new with the much less agressive Spec. Hemisphere Armadillo. This would give me a much better tire for my normal riding surfaces while still preserving some light off-road capability. Any thoughts, suggestions?
