So I am currently riding a Giant escape 2 and is looking for a decent entry level road bike for longer rides. My budget is around $600~$700 and I am currently looking at either a new 2015 Giant Defy 5 @ $620, or a used 2013 Giant Defy 1 (2013 Giant Defy 1 size M/L) for $700. I am going to LBS to try some others too (Trek 1.1) but I prefer Giant because it's more comfortable? Is used defy 1 a good deal? I usually prefer new bike because of initial support from LBS and warranty, but Defy 1 seems to be a much better bike than Defy 5.
