Hmm. That is a bit of a dilemma, but your thought processes seem logical. Here are some additional thoughts to add to the pile:
- When newer triathletes buy a road bike from us as their first "real" bike, they do usually return within 2 years to purchase a triathlon bike.
- When newer triathletes buy a triathlon bike from us as their first bike they almost never purchase a road bike from us. Those who do, seldom seem to use it and we tend to not see them on the group rides they mentioned they planned on doing if they did buy a road bike.
You may be a different bird, because you have road riding background. I'm constantly struck by the number of times we'll say to a fellow or girl we know fairly well, "Hey, join us this Sunday morning for an easy ride out to the island to show you the routes and try some group riding..." They are always polite and accept the invitation but seldom ever actually show up. I'll ask them why they don't show up if they are regular customers and they tell us thing like, "Oh, my schedule doesn't allow it- I couldn't get out that day." or they say they are concerned we would ride too fast (we wouldn't) or they voice concerns surrounding not having group riding skills. Some of these concerns are valid (schedule, skills) some are less so (we'd never invite riders on a ride and then go out and ride too hard for the group).
The bottom line is: The use of a road bike is largely contingent on the availability of group rides.
If you can't/aren't willing/don't have the skills to/can't find people to/are afraid to get involved in group riding then the road bike seems like it has become just a step on the way to getting a tri bike.
When I ride in a small group of riders I am compfortable with I almost always ride my tri bike. When I ride a group ride with more riders with whom I want to be a little more familiar before I am comfortable then I stick to the road bike.
I like having both and I get use out of both but I enjoy my tri bike more. It is simply faster and more comfortable.
