I am new to cycling. Have been to a couple of stores to try out some bikes. I have narrowed the bike selections to Jamis Nova, Bianchi, Surly and Fuji. Both Jamis and Fuji has better parts (shimano 105) than the Bianchi and Surly. But, everyone that Iíve talked to rave about the Bianchi and Surly bike. Is the Jamis Nova and Fuji Cross comp much lesser bikes? They are all about the same price regeon. Can anyone make a suggestion? I would mainly use the bike to ride around the city and trails in Mount Tam on the weekends.
