Carbon Wheels bikes are supposed to be more comfortable because they absorb the bumps of the road better. With aluminum, you’ll feel more of the bumps. I’ve only ridden on an aluminum bike (tri bike). I can definitely feel the bumps and ruts, even though I try to avoid them as often as I can. It’s not that bad though. If you are training for sprint and Olympic-distance tris, then aluminum shouldn’t be a problem. For longer distances, many would prefer the smoother feel of a carbon bike. Carbon Road Forks are generally more expensive, sometimes quite a bit more. A Carbon Rims Bike is a good idea if you are going to do a lot of group rides. They are easier to handle in close groups. You can still do some riding in groups with a tri bike, especially if your bike handling skills are well developed, but other people might not want to ride with you. Many stores have sales Carbon Bike right now .That’s what a real triathlete should be doing anyway.
