Hi all, I'm new to this complete scene, forums and bikes. I sold my walmart bike that I hated to ride and about to buy a Jamis Allegro 3 and start riding.Being 56 this looks like the place for me to hang out. can't wait to get started. I need some opinions on the gearing of the Jamis. Is 18 speeds enough for Florida or should I go for a bike with more speeds.
