there's a guy in ur club who normally rides 6 to 10 hours per day. He doesn't work and does serious long distance cycling. He rides a full carbon roubaix. he is looking at getting a new bike as well. He said he loves his roubaix for everything but crits (and tt's i guess). He said the roubaix is great for road races and fast club rides, but he wanted more aggressive geometry for crits. personally, i don't think it would make a big enough diference unless you are a very high level rider. as long as you are comfortable on your bike and in good shape you should be able to race well. Think about this. if you are more comfortable on this bike for long distances, you will be able to train more and do so more comfortably. i would think that at ametuer level racing that would be more useful than a race bike.
