I'm looking to buy a bike to do triathlons and to do bike rides. I do not plan on winning just competing. This will be my first road bike that is younger then me. I have $600 to spend.
I know nothing about bikes. I talked to sales people and theirs are best, I look online and get confused.
These are some that are in my area:

Kona Esatto
