I just recently went from a 48cm 2006 Redline conquest Pro w/ Ultegra (keep in mind I am 5'11" a 48cm was just a tad small
) to two bikes:
Road: 2010 Aerocat w/ SRAM Force 56cm
CX: 2011 Redline Conquest Pro 56cm built with full Rival
There is nothing I love more then riding my new Redline. Mind you the Aerocat hasn't seen the road but as far as I am concerned my Redline is truly my "best bike". For me it is functionality, feel, speed, handling, everything just feels perfect. And while many people tell me that toe overlap is not something to worry about, I am a city commuter, I like being able to do bike stands, toe overlap = PITA bike stands. Best of all worlds as far as I care.
