It's interesting what Baden says about a longer wheel base making a huge difference. When you think about it this makes a lot of sense as the wheels are further apart so creating natural flex and absorption through the frame. The longer wheel base also allows for a larger volume tyre to be used, and most of the serious contenders have settled on 27/28mm to be the optimum. For many a Roubaix bike is the perfect bike for all of the riding. Comfort and more stable handling are traits which new and seasoned riders can all enjoy, so no wonder this category continues to grow.
