I've been a bike commuter for years riding an EZRacer recumbent on a mostly flat route 20+ miles/day. I'm interested in getting a road bike to take up the nearby hills on weekends. I'm not interested in racing, just a fun, lightweight, good climbing bike. Test road Specialized's Ruby Elite and Expert bikes this weekend, liked the first, loved the more expensive second one. I've always had Shimano and found the SRAM hard to get used to. I am 5'6" with long legs, short torso, long arms and fit a 54cm. Looking for recommendations!
