Spec diverge A1 vs Trek ds 8.4

So these 2 bikes have shown up used on craiglist in my area. Both are 2016 models barely ridden. 700 bux for the diverge 650 fpr the trek. Im looking for a good commuter and something i can get into some of the area races with after i train up.

As. New both of these are way out of my price...
