I've pretty much decided, maybe irrationally, to get a new carbon bike. I've given my Specialized Sequoia to my wife, and though I love my steel Bianchi, I guess I'm just a bike ****. I'm not a racer, but I'm doing a fair number of long rides, working up to a century in a couple of weeks, and I'm looking for a combination of light weight, comfort, speed, and stability.
My lbs is in the process of finding a Roubaix Comp or Elite in my size so I can test it against a Cannondale Synapse they already have in stock. Before I do the test, I'd appreciate any opinions you guys may have about this choice, given my riding style, age, and size (67; 6'2", 190)
