I have a “Roubaix” style road bike. I’ve ridden it on three RAGBRAI’s. Is this the style bike I should be riding or is there something better for long, multiday rides? I also own a commuter bike that I love riding but not sure I want to push 40#’s of commuter bike that far and long when I can push 17#’s. What are some of the differences between a “Roubaix” and a standard frame road bike?
