What I noticed most when I was testing Jamis Aurora (pretty similar to the Coda, "dressed" as a road bike) was how beautifully it absorbed road buzz compared to my aluminum Kona.
Which one (Jamis or Trek) did you feel more comfortable on? Did one of them feel instantly like it was meant for you?
What matters most is how you feel on the bike. "Fit, function, and true love are all that matter."
Which bike did you love?
