Hey there. I have a couple old schwinns that I ride, but I want to put together a more "modern" lighter road bike for longer trips around town, including some pretty good hills. I think I want to put a hub gear system on it in lieu of a derailler, etc. I kind of like the hub gear (3-spd) on my traveler, and I've heard of newer ones that have 7 or 12 speeds or something like that. I was just wondering if anyone has used these much... just trying to get feedback on your experiences with these

thanks
