I have narrowed down my choice to these two: the 2011 Orbea Aqua T105 and the 2010 Avanti Cadent 1.0.
I can get both for $1800 with the major difference being that the cadent has a carbon frame but slightly lowers specs (brakes and wheels) whereas the Orbea has full 105 and MAVIC AKSIUM wheels.
I should also add that I am unlikely to bother upgrading components down the track.
I read that the Cadent is a relaxed geometry bike and this turned me off for some reason. This bike will be replacing my old banger which I use for a 20km commute to and from work each day and the occasional triathlon.
Any advice would be greatly appreciated.
