I am looking forward to riding again; I just love it! A little background on what have, and how I ride: A trek 820, with street tires. I love this bike, because it's strong, and since I put street tires on it in October, it's pretty fast for me. I ride almost exclusively on paved city streets, and don't ride aggressively. I read once here, at this forum, that putting street tires on a hard tail mountain bike makes one of the best street/city bikes you could want. I was thinking of getting a Trek Marlin or a Giant Talon or Revel or a similar Specialized bike, and possibly go to 700c tires. So, my questions are: Would trading up to a slightly more expensive bike be worth it? My Trek has a steel frame, and is on the heavy side, although this really doesn't bother me; would getting an aluminum frame bike be an advantage, a disadvantage or not really matter? Would the difference in geometry of a hybrid bike be better for street riding? If you recommend a bike, please keep it under $800. I'd love to hear some ideas.
