I'm trying to choose between a Quintana Roo Trueno (entry level tri bike) or a Klein Aura V road bike that I would add aero bars to. Either bike will be a big improvement over the bike I'm replacing (20+ yr old Fuji with a steel frame).
Most (if not all) of my riding will be alone. I have never riden with aero bars so I don't now how comfortable I'll be in that position for my rides (anywhere from 1-3 hours, 2-3 times/week). I enter a few tri's each year, mostly sprint distance.
I can get the Trueno for about $950, while the Klein will cost be about $1225 after adding aero bars.
The consensus here (for someone who participates in a couple of tri's/year) has usually been to suggest getting a road bike and add aero bars, if necessary. Plus, if you are doing sprint tri's, it can be argued that the aero bars aren't really necessary at all (they would make a small difference). If you aren't planning on finishing first, I would save the money on the aero bars. If you really get into lots of competetive tri's, then think about addind the bars, or even going to a tri-specific bike.
