Well, I think it's very common for an avid cyclist to have different machines (bikes) for different jobs.
For my group rides, I have a road bike. For my tri training and races, I have a tri bike.
Each one serves it's purpose when needed.
I also try to split my time equally between the two... so I can get tri training in and keep up with my road cycling and group rides.
