The Quintana Roo Kilo or the Trek Equinox 7. Im not sure which one to buy since Im new to this tri world, but he Kilo seems more appeling since i found it brand new for under 1000 bucks and ive heard it has very good components.
Ride em both. The geometry on each of the rides is different.
I will say that when you ride the E7, make sure they turn the seatpost around, so ya get the steeper angle. It rides MUCH better that way.
